* '''MC:''' I looked at it and think this is just due to the min/max/rms being offset into new groups that slightly change the of the waveform. (because the waveform does not display actual min/max/rms samples (there are too many) in blockfiles, but instead computes a new min/max/rms for the actual min/max/rms samples in groups that fit the width of the window.)

Revision as of 21:38, 26 August 2009

This is the de facto bug list for all Stable and Beta releases of Audacity. The current suggestion is that Beta releases are blocked until all P1 bugs are fixed, and Stable blocked until all P1 and P2 bugs are fixed. There is no pre-determined plan for dealing with lower priority bugs.

  • Items added as Priority P1, P2 or P3 should be added to Known Issues, unless they are absent from the published release that page refers to. When cleared, move the items down to the "Cleared in CVS" section of that page.

Please also refer regularly to these pages:

Documentation Checklist, for documentation changes needed for 1.4 Manual and any developer recruitment drive.

Wording, where we track suggested changes to the exact words that appear on a dialogue

Pending website changes where we post suggested wording or layout changes to our audacity.sourceforge.net and audacityteam.org sites (except the Wiki).

Unless indicated by discussion against particular items, these should be regarded as needing attention. When processed, please move them to the "Done" section of those pages.

  • There are companion pages to discuss and monitor development of our audacityteam.org sites: Wiki Development Checklist (for both this Wiki and the Manual Wiki) and Forum Development Checklist. Relevant items include security issues, bug fixes and enhanced functionality through installing additional extensions.

Essential changes

These are other changes to source code that are deemed essential. We will do all of these for final release candidate for 2.0.

  • Help/Manual issues
    • Installer versions of Audacity now install Html help. Suggestion has been made that Windows installer should have an option to install help for all users, not just current user.
    • Address documentation issues, including web site updates.
    • Completing the Manual.
  • Nyquist plug-ins (for 2.0): Gale to keep an eye on the Nyquist plug-ins provided in the Audacity Plug-Ins folder, possibly commit others requested by users if they work satisfactorily, such as binaural tones and Sequencer. On Windows/Mac, add the src/plug-ins folder to the installer but also add latest versions of GVerb.dll, Hard Limiter.dll and sc4.dll which are not in CVS. No special action is needed on Linux, as any *.ny plug-ins from the plug-ins dir are installed, except those deleted when the tarball is created using scripts/maketarball.sh.

Rating Keys for Issues

All issues are given a Priority Rating of 1 to 5 as follows:
P1 Blocks any Release - See the discussion page for a guide to what may be deemed an issue that blocks release.
P2 Blocks a Stable Release, but not a Beta. Maybe only affects a limited number of users.
P3 Not a blocker, but deemed worthy of release-noting if unfixed, so should not be ignored and left to mount up.
P4 Clear benefits from fixing, but not sufficiently important to release note. May include easy fixes giving considerable benefit relative to the time involved.
P5 Only just important enough to be fixed. It could be done in "spare time", or by someone learning the code.
Believed fixed but awaiting confirmation (cross-platform issues should be tested on at least two platforms)
R Regression on 1.2.6. Mainly used as an indication that a lower priority item could be promoted. Many issues not marked as regressions may well be so.

Blocking Issues

P2 (Stable Release Blockers)

P2 VST effects permanently in menu once cached, even if unavailable.
  • GA: Remove the effect, but it is still in the menu after rescan. Clogs up menu, and very confusing if user forgets effect has been removed then clicks on menu with no result.
P2 R View Menu: most menu items/shortcuts incorrectly disabled when playing or recording.
  • GA: The entire menu except History should be enabled if an audio track is open (except "Zoom to Selection" if there is no selection region present, and "Karaoke" if there is no label track).
  • AP: This should be fixed. Waiting confirmation. I've implemented this as you said (audio track present) but why shouldn't we be able to zoom in on a project with only labels?
  • GA: Thanks, André. Your fix is fine so far. I did not realise the View menu was disabled in the same way when having only a label, time or note track open. I thought it was only broken when playing/recording audio. Yes we want View menu to have all items enabled when there is any type of track open, but as before 1) "Zoom to Selection" is greyed when there is no selection and "select all if none" is off 2) Karaoke is greyed if no label track.
  • AP: Done.
  • GA: Thanks. Still a minor problem if there are no tracks of any sort - only "Show Clipping", "History" (if there is any) and "Toolbars" should be enabled. You could say the same about the first 6 items in the Transport menu and some of the Tracks menu.
  • JC: I rate the remaining problem a P4. With no tracks we see 'Play' as an option, for example, but I do not see that confusing people. Can we close this P2?
  • GA: Will demote after double check I've not missed anything. Then we can have a good P4 description. As in other cases, remaining problem was left in situ for a while in case student was still around, saw discussion and chose to fix it.
P2 Edit Labels: "start/end times display as zero" fix breaks screen reading ability.
P2 Revert "Metadata before export" and prevent this reversion overwriting aliased files if Metadata Editor is cancelled.
  • GA: Users cannot work out they have to click OK in Metadata Editor after clicking File > Export. Some click "Save" so become confused by getting an XML instead of audio file. Was extensively discussed on devel so I thought a summary here would save you time wading through that thread! We need metadata last (this lets it not be pointlessly shown when doing command line export), and then rename aliased files on export in such a way that cancelling the metadata editor does not overwrite them.
P2 R  (Windows) Projects crash when applying repeated effects on zoomed in regions towards the end of audio tracks
  • GA: Experienced on Windows XP in one project that crashed regularly on separate days but now won't do so, also several similar anecdotal reports. There is also an implication that Noise Removal is more likely than other effects to trigger the problem. JC suggested and was agreed we should aim to do stress-testing with small block sizes to try and force the problems to occur and (later added) that we should use the scripting feature to do this (improving our chances that we can repeat the problem) .
  • JC: A label issue? (I have not seen this crash yet).
  • GA: Without labels in my case, with in others, so believed that labels not relevant.
P2 Cursor jumps to start of scroll after playback cursor goes past scroll
  • GA: Import a file, place cursor in centre and zoom in four or five times. Then play a few seconds of audio so that the cursor goes past the scroll. Press Space and the timeline remains where stopped (maybe OK). Press Space again and playback restarts from original point but that is now at far left of scroll, not in the middle. The context preceding that playback position is now lost, requiring a fiddly drag back on the horizontal scrollbar, or a zoom out and back in. Or, you must draw a selection region when you may not want to do so. Very irritating for repeated zoomed-in editing at one spot.
  • JC: This is a P4, or better still a feature request for improved scrolling/zooming behaviour. Let's get some detailed usability enhancements written up for a GSoC 2010 idea? Then drop this as a P2. In this area I'd see 'zoom to selection' should be 90% not 100% zoom, so that we get context, plus also option for smooth scroll on sufficiently fast machines. Can we replace this P2 with a detailed/motivated feature request?
  • GA: Need time to consider exactly what may or may not be a feature request, however I and several others regard the subject issue as excessively disruptive to "repeat editing" workflow, and completely unacceptable. I've sometimes actually exported WAV and used other editors in order to be free of it.
P2 Nyquist effects, SoundTouch, SBSMS and Generators join separate clips together.
  • GA: The white space between clips is replaced with silence and a split line inserted at the left-hand boundary of the former clip (generators replace the whole region with the generated audio). To reproduce:
  1. Generate 30 seconds tone
  2. Click at 15 seconds, Edit > Split
  3. F5 and drag right-hand clip to start at 20 seconds
  4. Edit > Select all, then Effect > Change Pitch (Semitones value must be non-zero) ; bug should have occurred
  5. Edit > Undo, and Generate > Noise; bug should have occurred
  6. Edit > Undo, and Effect > Equalization ; no bug occurs
  • Claimed by Dan
  • DH: Should be fixed. (But other whitespace problems remain)
  • JC: Remaining whitespace issues are a P3 I think.
  • GA: Needs more testing and re-reading the discussion. I saw a few things that may be questionable, or may be heissenbugs . Other white space issues are spread through the whole program but probably P3 at a guess. Clearly the fix does not work at all for multiple tracks with clips (removes all the clip boundaries), and then does not seem to work again in that project, so I'm thinking it isn't fixed.
  • JC: I am getting OK behaviour with two tracks, 5 clips on each track. I used change pitch and then change tempo. I get extra clips (that are silent) inserted to bridge the gaps. Seems OK. The clip boundaries are still present for me. Can you add steps to repeat for the clearly-does-not-work part (if it is not a Heisenbug)?
P2 Ensure all Edit menu items consistently enabled and work consistently when select-all-on-none enabled. See here .
  • JC: Is it really what we want? E.g click split-new twice, and we get four tracks. Is it not less confusing to leave it greyed out?
  • GA: If you turn off select-all-on-none, and with one track on screen, Select All, Split New, Select All and Split New, you also get four tracks, so I think it is what we want. Now, if you have a track selected with no time area selected, nothing on the clipboard and click the Edit menu, all the edit menu is enabled except Paste. But if we click outside the track(s) so that none are selected, we lose ability to click on Split Cut, Trim, Delete, Split Delete, Silence, Join, Disjoin, Duplicate and Find Zero Crossings - yet we could still Cut, Copy and Split (FWIW) and Split New. I think that will be very confusing as it's a halfway house between Select-all-on-none and not. So all Edit menu items, and File > Export Selection to be available even if no tracks are selected and when clicking outside the tracks.
  • David B. suggests longer term having two independent preference options for selecting all tracks and selecting all audio to give more control.
  • MJS: I suggest (after reviewing the menus):
    • Leave grey:
      • "Export Selection..." - there isn't a selection.
      • "Split Cut" / "Trim" / "Split Delete" / "Split" / "Split New" - they make little sense without a selection.
    • Allow with "select all":
      • "Cut" and "Copy" - to cut/copy the whole lot and paste into another project, maybe?
      • "Delete"
      • "Silence Audio"
      • "Join" - to join up everything
      • "Detach at Silences" - as above
      • "Duplicate" - as above
      • "Mix and Render" - makes sense
      • "Resample" - makes sense
      • "Remove Tracks" - makes sense
      • All (most?) of the effects.
  • JC: I agree with MJS. I think this is what we want.
  • GA: My view is that only Export Selection, Trim and Split should be greyed. May be a case that Split is enabled and selects all tracks if no tracks selected but cursor in track. Important that all other agreed menus are enabled when no tracks selected.
  • Claimed by Dan
  • DH: Think I need to add another flag to fix this, as there are items in both the 'allow' and 'disallow' lists with identical flags.
  • DH: Scratch that, I did it a different way. The behaviour suggested by MJS should be implemented now, although it would be a good idea to keep an eye out for any other changes that I may have inadvertently made. But 'should be fixed'.
  • JC: I think what we have now is good. We can argue about what to do in some cases, e.g. if select-all-on-none isn't able to select any audio because of an empty track. However it doesn't seem confusing and works well. I vote we close this.
  • GA: Still inconsistent between clicking in or outside the track. I'm not sure yet if this is in fact a sort of compromise between my idea and Martyn's. Will likely remove but not going to rush it.
P2 After split-new further splits (at a point) may shorten audio.
  • JC: Generate a track e.g. DTMF. Move so that does not start at zero. Do split new. With select-all-on-none not ticked, place cursor on some generated audio so that there is not a region selected. Click split. It should just add a split at that point. Instead the audio gets shortened. I'm not sure how reproducible this is yet. If we get it 100% reproducible I'd think it becomes a P1.
  • MC: Was able to produce 100%. Fixed pending verification.
  • GA: Fixed according to description, but what about the waveform distortion occurring after you split at any point? Generate a 5 seconds DTMF, click at 1 second, Edit > Split and compare Undo and Redo waveforms. It does not look like just a sideways shift to accommodate the split point. Easily evident with music too, not just a tone. Separate issue obviously, but would like some input.
  • MC: I looked at it and think this is just due to the min/max/rms being offset into new groups that slightly change the of the waveform. (because the waveform does not display actual min/max/rms samples (there are too many) in blockfiles, but instead computes a new min/max/rms for the actual min/max/rms samples in groups that fit the width of the window.)
P2 (was P3) Labels should move with all the timeline changing effects. They do not move with Effect > Repeat, Reverse, and Truncate Silence.
  • AP: This should be fixed now. Waiting confirmation.
  • GA: Truncate is incorrect if applied to multiple tracks. Remove two audio tracks above and Generate DTMF (duty 55, tone 2185, silence 1788). Duplicate it and move label track to bottom. Select 5 to 8.5 seconds and Truncate Silence (max 200). If linking is on, audio after the silence is deleted and the label disappears; if it's off, it doesn't. But if the audio being truncated wasn't identical between tracks, the truncation would likely be flawed anyway, because of the way Truncate behaves with multiple tracks. Close this bug and flag up Truncate issues applied to multiple tracks as a lower-rated bug? See this thread.
  • AP: I think Truncate Silence with multiple tracks when link is on has no logical behavior associated. Check the thread above.
  • GA: Subject to Truncate Silence working in some fashion with multiple tracks, there may be a reasonable case for it to work with groups. Still being discussed in above thread.
  • André has a commit in place to fix, needs testing
  • JC: LGTM. Can we close this?
  • GA: No, not fully tested yet, and as usual heissenbug behaviour was evident when I first looked.
  • GA: This problem at least with Truncate Silence and multiple tracks remains reproducible (tried on three separate days, so not Heissenbug):
  1. Generate 30 seconds Chirp
  2. Tracks > Add New > Audio Track
  3. Generate DTMF of 30 seconds
  4. Apply Truncate Silence (max silence = 10) to DTMF
  5. No truncation occurs
  6. Remove Chirp track and try Truncate Silence again
  7. Truncation works
  8. Does not depend on vertical position of tracks or linking. Many complaints about this on [email protected] Strong P1 candidate I think.
  9. Then duplicate DTMF and try and generate Noise into it. Nothing happens (this is just noticed tonight so may be Heissenbug).
P2 (Windows 7) Runtime Error Program: (location) R6034 on launching Audacity.
  • GA: Fixable by user changing compatibility mode to Vista SP2 or XP SP3. Reports where this error occurs say Audacity installs without compatibility, but that isn't in itself a condition to reproduce it.
P2 (Windows Vista, 7) Input sources cannot be selected in Mixer Toolbar.
  • GA: A significant problem for support workers. On some systems, running Audacity in compatibility mode for XP seems to make the inputs appear in Mixer Toolbar and work/be selectable. Best solution could be to integrate Device Toolbar into Mixer Toolbar, making sources appear as separate devices for all Windows versions, with the sliders above the respective dropdown. Cheaper short-term solution may be to turn Device Toolbar back on as it is. See proposal.
P3 (Windows Vista, 7) Audacity input/output level sliders act independently of/incorrectly with system level sliders.


  • Achieved recorded level only matches level indicated on the Recording VU meter if the Audacity input slider is at 100%. (DB finds similar behaviour on XP with Logitech USB microphone, but GA can't reproduce with USB external sound cards).
  • (DB finds this only on Vista) Launch Audacity > Record > Stop > adjust the system input level > Record again; or Launch > adjust system input level > Record resets system level to that before the adjustment, unless monitoring is on. Please test with both motherboard and external USB devices. Adjusting system slider is necessary if it happens to be set above clipping level because lowering the Audacity slider only scales down the clipped signal instead of lowering the system slider. Especially confusing for VI users.
P2 (Linux only) Crash undoing a label edit, or repeatedly undoing/redoing addition of a label or a label track.
  • LLL: This is (probably) fixed now...just needs verification.
  • GA: It seems identical characters in the label names is something to do with it, and Undo/Redo of label edits is still very unstable. I found this scenario gives me a replicable crash on Ubuntu CVS ANSI build:
  1. Open Audacity and create a 30 second sine tone
  2. Click at 3 seconds, CTRL + B, type "ase1" (without quotes) and ENTER
  3. Click at 8 seconds, CTRL + B, type "ase2" (without quotes) and ENTER
  4. Edit > Undo three times, it should crash on "Undo Label", if not before.
    Note: do not make any typos entering the labels or the bug may not reproduce.
  • SteveTF adds:
  1. Launch Audacity and add a label track
  2. Delete the label track by clicking on the [X]
  3. If it does not crash, try pressing CTRL+Z to undo, then click on the label track [X]. Repeat as necessary.
  • GA: Removed separate P4 "Intermittent crashes removing a label track" as it would appear this is the same bug and should be dealt with at the same time. That P4 was commented:
    • Adding a Label Track causes Edit > Paste to flicker (the code does enable it), then closing the Label Track causes a replicable crash (reported by Darren)
    • Removing an audio track then a label track may crash multi-track projects, reported by Zach.


P3 Release Noted (Prioritised non-blockers)

P3 R  Unreliable project re-opening with orphaned and missing blockfile errors.
  • GA: There are reports every week of users losing data correctly reopening a 1.3 .aup file in the exact same 1.3 version they created it in. "Orphaned" or "missing" blockfile errors are received and when users accept the "recommended" course to delete, the project is silenced. This frequency of data loss is not acceptable in 1.4.0. We should be on the alert for these issues, and as soon as steps to reproduce are found, escalate the specific problem to P2. One definite scenario where this has been reported is having multiple projects open, and blockfiles are saved to the wrong _data folder. GA has not yet managed to replicate it, though still has some more reported steps to try and do so...
P3 R   (reported on Mac) Unreliable project re-opening due to duplicate attributes
  • GA: When a saved project is re-opened it fails with "duplicate attribute" error. Almost always involves imported MP3s; the .aup file shows one or more tags with two "name" attributes, for example <tag name="ARTIST" name="ARTIST"/>. Changing second "name" to "value" allows project to re-open. GA (Windows) and a Mac tester have tried to reproduce this with an MP3 that created this issue for one user, but the projects re-opened perfectly. Bug also reported to occur if a diacritic is included in a label.
  • GA: One report from CVS on Mac 06 July 09 finds a project with diacritics in labels that saved in 1.3.7 with duplicate attributes saves correctly in CVS.
P3 Unreliable Automatic Crash Recovery.
  • LL: I've seen some really strange (attempted) recoveries. I haven't yet looked into them, but I shall soon since my wife is complaining about it as well.
  • GA: These known problems have been reported. They should be verified and escalated to P2 if valid:
    • If a crash occurs with two tracks open, multiple projects are recovered
    • Recovery fails if a track is imported then another added after the autosave interval
    • Complete recovery failures (empty projects) seen on single tracks which are only generated tones.
    • (Mac) freeze on Intel Macs when starting recovery
    • (Mac) (Intel and PPC) "Junk after document" warnings then recovered project is empty. See here and download here an example auto save file and _data folder.
P3 R  AIFF files created by Audacity from recorded or generated data import intermittently (but at times very frequently) as noise - files play fine in other software.
  • GA: Much of the time, 1.3.7 or later on Windows cannot be relied on to import files exported with the explicit "AIFF (Apple) signed 16 bit PCM" filter. Appears to affect exports from recorded data (at any Defauit Sample Rate), or from tones generated at 24-bit. Same problem occurs with the AIFF 24-bit option accessed with "Options" button, but not apparently the comparable 16-bit option. Export Multiple seems affected the same way as regular export. Tested at 44100 Hz, reading directly. On Mac, a user 22 March 09 reports 1.3.7 "suddenly" producing noise when importing AIFF files where it did not before in many similar imports - user changed default sample format to 24-bit at about the same time. More details here.
  • LL: Gale, have you been able to find a pattern to recreate this? I've tried numerous variations on OSX and Windows and it always seems to import ok.
  • GA: Are you using a release build? In ANSI Release from HEAD, I created a chirp tone in 24-bit quality, recorded it using stereo mix then exported only the recorded track using the explicit (no options available) AIFF (Apple) signed 16-bit PCM choice. I changed Quality to 32-bit, closed the tracks and repeated the generation, record and export. I am not getting noise on importing the files back into Audacity but what I can replicate is that about half the time the files will crash both HEAD and 1.3.7 Unicode Release; if they don't crash they import properly. So behaviour compared to when I last tested is not the same. I have tried importing with the "All supported files" and "FFmpeg-compatible files" filter and the problem is identical. In 1.2.6 I can import these files dozens of times without problem.
P3 Automatic Crash Recovery: disregards track zoom level and position.
  • GA: Always opens tracks at normal zoom level viewed from time zero.
  1. Import a 3 minute or longer file into fresh project, which fits to project
  2. Force quit and recover, and first 10 seconds of track reopens from h=0
  3. Also replicable by generating 30 seconds tone, zooming into a selection in the middle, wait the autosave interval and force quit; again recovered track shows first 10 seconds from h=0
P3 Time Track disables audio/label linking.
  • GA: Steps to reproduce:
  1. Add a tone of 30 seconds in a clean project with linking enabled
  2. Select 5 - 10 seconds, CTRL+B and name label
  3. Tracks > Add New > Time Track
  4. Select 2 - 4 seconds in the tone and Edit > Cut; audio is cut but label does not move
  5. Edit > Undo
  6. Remove Time Track and repeat step 4; label moves back to respect cut audio
P3 Label tracks: typing "j" or"k" in a label may activate the "move cursor" shortcut instead.
  • GA: Not reproducible to order, but very likely to occur with large numbers of labels in a track. Once it occurs, typing "j" or "k" in any label in that track will move the cursor to start/end of the track.
P3 Changes in available devices not detected without restart.
  • GA: A significant reason for users' USB devices not appearing in Audio I/O Preferences.
P3 (reported on Windows) Timer Record unreliable with recordings straddling midnight
  • GA: If recording starts on one day and end on another, recordings may carry on after scheduled end time and cannot be cancelled, requiring a force quit of the application. Elapsed and remaining time will appear frozen at some values consistent with the schedule. No repeatable scenario is known, but for those regularly scheduling midnight spans, the freeze occurs quite regularly. A system clock change is a possible explanation (see next item).
P3 (reported on Windows) Timer Record cannot maintain scheduled duration if system clock changes
  • GA: Schedule a five minute recording for immediate start (start time immaterial), OK, then change system clock to one minute before end of recording. Elapsed time and remaining time will jump to reflect changed system time, and recording will end having produced just over one minute of recording.
    Schedule that recording exactly the same and change system time to one minute after the end of the recording. With 1.3.8 Alpha from 04 June 09, recording will cease immediately, having produced a few seconds of recording. In a previous test of 1.3.8 Alpha from 29 April 09, an hour long recording straddling midnight had its elapsed and remaining times frozen when system clock changed to after end of recording, and carried on after originally intended duration, but could be cancelled. Repeating that same hour long test straddling midnight in 04 June 09 build simply aborts recording when time changes, yet Timer Record code did not change between those dates.
    Are these fixable by relying on a Widgets timer for duration? Many people synchronize system time to online atomic clocks (Windows XP does it by default).
P3 Modal block circumventable using File > New (Mac only) or shortcuts, leading to risk of crash. See this thread.
P3 Muting specific time-shifted mono tracks when exporting produces audio at wrong point on timeline in exported file if muted tracks are to left of unmuted.
P3 WAVEX (Microsoft) headers: GSM 6.10 files cannot be exported, and U-Law/A-Law files may not be playable.
P3 LADSPA Multiband EQ may not be visible in Effect menu (occurs on Windows XP), and crashes soon after opening.
  • VJ: The logic needs to be fixed to set rstart to a valid value in all cases, because after initializing rstart to 0, it crashes in LadspaEffect::ProcessStereo().
  • LL: I think we've gotten past that, but now there's a crash during cleanup. It's due to a memory overwrite past end of the "comp" array in the mbeq source. It's been fixed in the LV2 version of the plugin, but AFAIK has not been fixed in the v1 plugin. Correctly the logic allows the plugin to process without crash.
P3 Residual FFmpeg issues:
  • "Select file(s) for batch processing..." dialogue lacks "All Supported files" and "FFmpeg-compatible files" filters
  •   Importing FFmpeg formats when FFmpeg library missing should raise the "FFmpeg not found" error, not the generic "not supported" error. Provisional fix in place, but throws multiple FFmpeg errors per file, then the relevant error for the particular format
  • In non-FFmpeg builds, attempting to import FFmpeg-supported formats should give an error that suggests downloading FFmpeg. Impossible to fix completely without breaking Importer abstraction: in non-FFmpeg builds ImportFFmpeg plugin does not exists and cannot suggest anything to user, while Importer should not know which formats are supported by ImportFFmpeg, thus being unable to suggest anything either.
P3 On-Demand: when importing a mixture of uncompressed and compressed files, on-demand loading does not start until normal import of the compressed files completes, if the names of the compressed files come earlier in the alphabet.
  • GA: On Windows, video files with a preceding name which similarly held up on-demand loading are as of 07 Oct 08 now importing second when dragged in, so the OD file is not delayed, but the tracks are now out of alphabetical order in the track list. Also, correct alphabetical order when using File > Open or Import now depends (on Windows) on the order the files are selected in. GA suggests therefore we could prioritise OD files to import first, then re-order the non-OD files in the track list if needed.
  • MC: Fixed 14 Dec 08.
  • GA: 24 Jan 08 - not fixed on Windows, except that files now import in alphabetical order irrespective of the order they were selected in. The basic problem remains: using "All supported files" filter, any compressed file (audio or video) that has a preceding name prevents OD loading of an uncompressed file with a following name. until the compressed file has loaded. So, much of the benefit of OD loading is lost.
  • MC: Discussed in Feb. 09 as resolved for the time being, but the discussion is still open. The implemented solution is different from planned to minimize UI blockage: Order of sort depends on loading method (if open is used, OD imports first).
  • GA: Order of sort depends on loading method on Mac, but on Windows the non-OD file always comes first with both drag/import and open. Therefore, sort order is always wrong if the non-OD file comes later in the alphabet, and we're not getting any benefit on Windows of OD files loading first. Do you see a way of getting OD to come first on Windows when using Open or context-menu opening? And is a resort after load practical? Out of order loading remains I think a P3 issue in itself.
  • MC: I forgot about the windows open behavior - it should be different. I just verified it on the mac, so I will need help or access to a windows machine to debug this. But in general the non OD files come first so that the UI isn't blocked while the OD files are being loaded, and thus the user can have the most time interacting with with the project while the files are being loaded. The new method still has sorted order, but its new sort hierarchy is filetype first, then name second, which seems like a reasonable behavior to me. A post-resort of the tracks seems actually disorienting, since the user is watching them being placed in this order as the files import. Thoughts?
  • GA: Yes thinking about it, I agree a post-load resort probably would be disorienting. I'm just conscious though of complaints about not importing in file name order, which I think is what the user will be aware of. If we drag in B.mp3 and A.wav, can we place A.wav above B.mp3 to begin with, when it starts to load?
P3 Preferences window: OK button does not respond to ENTER when a tab is selected in the left-hand panel.
P3 When changing language in Preferences, some elements don't change until restart. Affects Audio Track at the top of the Track Drop-down menu, and the toolbars tooltips (except Selection Bar).
  • LL: It looks like this has been partially fixed...the track menus now change, but tooltips are still an issue.
  • LL: This should now be fixed...just needs verification.
  • GA: Still an issue with generic track name ("Audio Track" in English) and Meter Toolbar channel names not changing, and with Selection Toolbar elements running into each other: after changing from English to French; then restarting and changing from French to English.
P3 R Pressing Play (but not Space) or clicking on the timeline in a second project when another is already playing stops playback of the first project.
  • zachelko: On Windows with Audacity 1.2.6 I'm not experiencing this. However, what seems to happen is that if a track in one project is playing and you attempt to play a track in another project, the play button does nothing and the track isn't started. Was this possibly the "fix" ?
  • GA: Because 1.2.6 does not have this problem, the bug is marked R , denoting it is a regression against 1.2.6. To replicate all issues on this list and Release checklist not aiming for 1.4, please test against latest CVS HEAD.
  • zachelko: This issue is deeper than just the "Play" function. Pressing Play, Pause, or Stop in another window while a track is playing in a different window behaves as if you hit those buttons in the window that has the playing tracks. I'm looking into a fix for this now. Was ControlToolbar.cpp over-hauled since the 1.2.6 release? By looking at it for the past 30 minutes or so, it would seem that a lot of these protections would have taken place in here...
  • zachelko: Submitted patch to mailing list 3/19/2009 to address Play/Pause/Stop spanning across all open windows. Timeline issue still exists.
P3 Calculation of "disk space remains for recording (time)" incorrect when recording in 24 bit quality. Macro now created by RA to return size on disk of 16/24/32 bit sample formats as 2, 3, 4 respectively as first part of a fix, but Audacity does not currently record in 24 bit.
P3 Tag import/export occasionally non-orthogonal. Some known specifics:
  • WAV fields only seen patchily by other apps. as their support is patchy, but Genre tag consistently not seen.
    • GA/LL: Although it's a valid WAV info tag (IGNR), we don't support it because current and next libsndfile doesn't. We could patch libsndfile locally, but may be better to switch to taglib when they next release, as that will have AIFF and WAV support. Also because AIFF is written to an ID3 RIFF chunk, that will support AIFF tags in iTunes as standard instead of the current ad hoc adding on to libidtag.
  • GA: OGG metadata seems perfect on Windows except VLC sees no tags at all. How is Linux/Mac? Taglib should improve compatibility with VLC, K3b and Amarok.
    • GA: As of 12 Aug 09, Audacity cannot see any of its own FLAC tags in 1.3.9-alpha on Linux. Confirmed by STF.
P3 Nyquist implementation: Values appearing in effects text boxes are not always the hard-coded/previously entered values.
  • GA: Values seem to be re-computed from the pixel values of the slider as visible on-screen, so the nearest value obtainable by using the slider is presented when re-launching the plug-in, rather than the coded default or last entered value (example: highpass.ny). Compute the value from the text field then set the slider? See this thread
  • LL: The first part of the issue "100 becomes 101" will have to be resolved and is happening at the lines mentioned in the report. However, this only occurs on redisplay of the dialog. So, if you enter 100 and click OK (or press ENTER), 100 is what will be used when applying the effect. The second part "1.0 = 0.997" is normal floating point behavior.
P3 (Windows only) After a period launching correctly, Audacity opens minimised.
  • GA: Audacity does not come up on top after launch, requiring right-click > "Maximize" or "Restore" over Taskbar icon, ALT - tab or resetting .cfg (the latter always works). Some users believe Audacity has "stopped working". One user claimed these were the .cfg settings before resetting them:

    [Window] X=-4 Y=-4 Width=1288 Height=778 Maximized=1

P3 (Windows only) LADSPA plug-ins not categorisable despite compiling with USE_LIBLRDF defined and installing RDF data files in Audacity data directory. See this thread
P3 (Windows only) The slv2 library needed for LV2 support does not build.
  • GA: Is slv2 building on Linux?
  • DanH: For me it fails (on Linux) but can be fixed by running libtoolize.
P3 (Linux only) JACK issues:
  • in 1.3.5 from Ubuntu repository, Audacity crashes as soon as play or record started if JACK device selected in preferences (not tested built from CVS)
  • JACK has to be shut down before starting Audacity
  • Connections in qjackctl not persistent in Audacity session: they only become visible when playback or recording starts, and close when playback or recording stops. Several Linux applications have this problem, but for example alsaplayer seems to have solved it by changing their code? See this Linux musicians thread and this Forum post
  • Recording dropouts - these are grouped together with similar Mac problems as a P4 issue, but they might not be related
  • Crashes when recording full duplex?
  • Audacity must have same sample rate as JACK (seen in 1.3.4 Ubuntu repository builds)
P3 (Linux) Audacity output slider may affect playback meters.
  • GA: If Portmixer uses emulated playback volume rather than native, the Audacity output slider will affect the VU playback meters and these may not then reflect the actual volume level of the waveform.
P3 (Linux only) Effects and other dialogues do not have focus on opening.
  • GA: This is a bug in wxGTK for which there is no current workaround. Click in the dialogue to navigate it and change parameters.
P3 (Linux only) After opening a sufficiently long audio file, opening a second file of any size leads to locked GUI/console messages until first file completes play. Reported by Michael Schwendt on Fedora 8 test rpms of Audacity CVS from 11 Jan 08 and Jim Cline on Debian 31 Jan 08.

  • DanH: Confirmed on Arch
  • JC: Therefore promoted from P4

P4 / P5 Other Issues (not Release Noted)

P4 Analysis effects that create labels should give focus to label track.
  • GA: To reproduce:
  1. Generate DTMF tone sequence
  2. Edit > Duplicate twice to create four tracks in all
  3. Select the top track and Analyze > Silence Finder (default settings)
  4. Analysis track (the object of the last action) invisible without scrolling
P4 "Specify Command Line Encoder" needs a dropdown to store entries.
  • GA: This is agreed with LL now that FFmpeg supported as well as LAME.
P4 Phaser and Wahwah: some sliders do not respond to arrow keys.
  • GA: Sliders affected: Phaser: LFO Start Phase, Feedback; Wahwah: LFO Frequency, LFO Start Phase, Resonance
P4 Vertical ruler scale only has zeros on a recorded track displaying Waveform (dB) view.
  • GA: Steps to reproduce:
  1. Launch Audacity
  2. Record a few seconds of stereo audio
  3. Stop
  4. Change to Waveform (dB) view if Default View Mode in Preferences not already set to it
  5. Only figures on the vertical scale are "0" and "0"
  6. Drag track down to see the real figures
    Does not happen with imports, or at waveform/meter dB ranges of -36, -120 or -145.
P4 Analyze > Plot Spectrum needs progress dialogue.
  • GA: On slower/stressed machines, selecting audio near to/exceeding the 237.8 seconds analysis length can result in excessive wait before plot or warning appears. I've seen up to 20 seconds' wait selecting an hour long track on a 2.4 GHz 1GB RAM machine with Firefox running. Warning should occur before progress dialogue.
P4 Play-at-Speed slider should have 6 steps using page up/down, and 60 using arrow keys. For input/output sliders, 5 up/down and 100 using arrow keys.
P4 Export Multiple success dialogue: untitled files after the first should still include "untitled" or "empty" in the name
  • GA: Since there is no other specific information to help users who have left just one label blank, I wondered if we should replace "untitled" with "empty_label" which makes it clear? I think people would prefer that the second and subsequent files included "empty_label" or "untitled" though. So, "empty_label.wav", "empty_label-2.wav" and so on. Is that easily done? I do think "empty_label-1.wav" for the first file "would" have been better, given we adopt this -1, -2, -3 ... scheme for "numbering consecutively".
  • LL: Not sure if "empty_label" would work if there are other cases when a blank filename were possible. I can't think of any off hand though, so if you can't either, we'll change it to "empty_label". The problem with having "-1" is that it really isn't a counter of the label being exported, it's a counter of what files already exist with the name. But, let me fiddle with it a bit. I think I have a solution.
P4 Export Multiple success dialogue cannot be dismissed with ENTER.
P4 Chains: all effects should remember settings applied via chain and Effect menu independently.
  • GA: Leveller, Normalize and Truncate Silence already do this, including applying the effect menu settings when you use "Repeat last effect", even if the effect was last applied in a chain. Equalization still needs fixing in this regard. If you apply one EQ in Effect menu, another in a chain then Repeat last effect, the EQ from the chain will be applied even though the one visible if you open EQ from the Effect menu is the one last applied from the menu.
P4 EQ: Can't save a flat curve.
  • GA: Steps:
  1. Load EQ window with RIAA preset visible
  2. Click "Flat" button as save preset as "Flat" or other name.
  3. Click OK or Cancel
  4. Reload EQ window. The RIAA curve will display (as "Custom", as I think intended), and selecting "Flat" preset shows that it is actually the RIAA curve.
P4 Toolbar and track gain/pan sliders should display current slider position on hover
  • GA: Too fiddly and undiscoverable for sighted users to have to click on slider to read the current setting.
P4 Users insufficiently aware of "export" because the word is not found or understood.
  • JC: Possible solutions include moving export next to save-as in menu and navigation from save-as to export.
  • GA: Navigation solution probably too confusing; naming/ordering of menu items, and (possibly) tooltips over menus or status bar indications probably more productive. See this Forum topic. Issue is more than cosmetic because of support overhead answering "how can I join the .au files I saved so I can play them in iTunes"; and because greater prominence of "export" would reduce the risks from over-reliance on projects. These are fragile in novice users' hands, and occasionally unreliable due to not-understood bugs in the code.
P4 Recordings of audio played in Audacity are truncated by approximately 100 ms.
  • GA: To reproduce:
  1. Generate 2 seconds tone
  2. Record from stereo mix (or line-out patched to line-in) with "overdub" on
  3. observe the last 100 ms of the track above is missing from the recording
P4 "Automatically fit" preference: resized track snaps back to fit after any edit or gain/pan change.
  • GA: Many users find this irritating because you cannot adjust gain and pan in one step, or leave track dragged down while adjusting gain/pan.
  • GA: Agreed solution is to change behaviour so that fitting only occurs automatically when adding or deleting a track.
P4 "Automatically fit" preference: tracks not re-fitted if tracks added or deleted then undone/redone.
P4 "Automatically fit" preference: Time, Label, and Note tracks not re-fitted.
P4 "Advanced Mixing Options": Names of all input tracks scaled unreadably small if any input tracks have a long name.
P4 "Advanced Mixing Options": right channel of unsplit stereo pair called "Audio Track - Right".
  • GA: Confusing if you have other tracks not renamed from default because you cannot tell which is which unless you know ordering is done by track position. Note: If you "Split Stereo Track" the fault is corrected (even if you "Make Stereo Track" again).
P4 Selection bugs when zoomed in
  • GA: may also be (partly) responsible for unpredictable behaviour dragging clips - see here
P4 When Control Toolbar is undocked, its associated shortcuts only work if the main application has focus.
P4 Minimum and maximum frequency display in Spectrograms preferences don't work for spectrum log (f) view.
P4 Memory leaks:
P4 Nyquist implementation: Excessive memory usage
  • LL: This will have to be resolved by adding memory pool tracking to lib-src/libnyquist/nyquist/nyqsrc/falloc.c so it can be freed when needed.
P4 (Mac only) Command-modified shortcuts that are also system shortcuts always perform the system action. For example, Command-M does not add label at playback position, but minimises the app. List of system shortcuts.
P4 (Mac only) CoreAudio crash when input device's sample rate is 44100 and the output device's sample rate is 48000.
P4 (Mac only) Envelope points do not restore properly when reopening a saved project -see here .
  • BP: Reproduced on 1.3.3 - 10.5.1, PPC iBook G4 on 28 Mar 08, but *not* on Intel Mac
  • GA: Should be tested with CVS HEAD and PPC, and escalated to P2 if confirmed?
P4 [LL] (Mac *and* Linux only) Random bits of silence occur during recording (Jack and non-Jack versions of this problem).
  • JC: Progress: Udo tried smaller blocksize in linux/jack version of this problem and can now fault after 4 mins. Perhaps small blocksize will help us track down the problem on non-Jack set ups too. However, perhaps Udo's progress is only relevant to using Jack and no help to Mac? And this problem does not occur consistently on a given system?
P4 (Linux only) Defining EXPERIMENTAL_SCOREALIGN prevents building on Linux.
P5 Find Clipping: needs decision on optimal behaviour with regard to when/where created, linking, and label retention if re-run in same track.
  • AP: Create a Label track and call it Clipping, now add chirp track and Find Clipping. All the labels will be added at the above label track even when linking is on. Shouldn't we create a new track named Clipping at the bottom in this case?
  • GA: +1. Rather than add multiple behaviour options maybe we should decide "best behaviour". IMO this is that Find Clipping opens a new "Find Clipping" track if there isn't one already that has been created by that action; extra clipping (or normal) labels can be added to it, but it's disregarded as a linked track.
  • JC: I prefer that 'clipping detected' labels do participate in linking. However if any analysis effects clear out labels before adding new ones then they should always do so without affecting audio....
  • GA: But that exposes the contradiction that removing labels in a normal label track *would* delete the audio. Plus if the clip track is created underneath a linked group, it won't behave as a linked label track anyway. So I came to the conclusion the least confusing solution is that clip track behaves independently of groups.
P5 Meter Toolbar: Right-edge hover corrupts cursor.
  • GA: Hover over the right edge without dragging, then the cursor will always have drag icon wherever the mouse hovers over the meters, until that window is closed.
P5 "Latency problem" warning when audio is pushed behind zero occurs for both tracks of a stereo pair.
P5 R (Windows only) Executable will not launch in Safe Mode but runs an unkillable process.
P5 Pressing OK in Preferences removes action-specific text in last Undo menu item.
P5 Standardise per-platform behaviour after changing Default Sample Rate in Preferences: On Windows, changing the rate in Preferences changes the visible project rate at once, so affects all new tracks in current project. On other platforms, visible project rate does not change until opening a new project. This creates problems in the Manual. Windows users seem to like current behaviour and report a bug if the visible rate does not change. We need to decide. Similarly, on Windows, a new track in the current project takes the changed default sample format at once.
P5 Debug Log window and Help > Index... browser do not escape.
P5 Links from built-in text to Wiki to be locally over-ridable in the same way that links from built-in text to external html files can be. This way we can have a local copy of the relevant Wiki pages, if we want to.
P5 Dependencies Dialogue: If click on "Copy Selected Audio Into Project" in error, the copying cannot be cancelled from the progress dialogue.
P5 Nyquist implementation: (dribble [fname]) function
  • STF: Creates a file as expected, but the file is empty (zero bytes). Not a problem in standalone Nyquist.
  • GA: LL has noted previously that all XLisp and Nyquist functions are now available, so file writing in itself should not be a problem.
P5 Nyquist Prompt should be categorised as "Utility".
  • GA: It would not then be left unsorted if EFFECTS_CATEGORIES was on.
P5 Nyquist: s-add-to sound max-samples "file-name"and s-overwrite issues
  • Dave Storer: see these details.
  • GA: I've noted this so it might provide a reminder for Roger D. to take a look, but as you note, these issues are in Nyquist, so not a specific problem with our implementation of it.
P5 (Windows) If Windows Taskbar positioned at top, title bar of "Welcome Message" is obscured.
  • GA: Does not affect the other three edge positions.
P5 (Windows only) Timer Record progress dialogue reappears underneath programs restored to the desktop after hiding the dialogue with "Show Desktop". Also the progress dialogue ought to disappear with the WIN + M equivalent shortcut, but doesn't.
P5 (Mac only) When Preferences set to "Update display", trying to change timeline position during playback (for example by dragging horizontal scrollbar) causes playback cursor to desynchronise until playback stopped.
P5 (Linux only) Intermittent crashes using Undo command (irrespective of command being undone).
  • Reported by Darren on Ubuntu Gutsy 7.10 with 2.5 GB projects.
P5 (Linux only) Recovery action if project rate not supported by card. OK on Windows.
  • GA: What does this mean exactly? Is it that the project rate is not remembered when recovering as reported on -devel list in May 2007? As at May 08 it is set on Windows.
P5 (Linux only) Miscellaneous OSS crashes.
  • Crash reported by SIEGERSTEIN: 'failed in 'src/hostapi/oss/pa_unix_oss.c', line: 1206'
  • Mihail's issue: PA19 uses oss; without load/compile oss support in alsa (snd-pcm-oss), Audacity crashes on init PA19.
  • GA: Are these still replicable or are they fixed with the PA updates?

Not aiming to do for 1.4.0

This has moved to release checklist not aiming for 1.4 and now includes former "Aim tos" from this page. Many of these "Aim tos" are relatively small items but could nonetheless make a worthwhile difference for the time involved. Please do not forget them.

If you claim ownership to items in "Not Aiming", please cut them from that page and park them here:

Truncate Silence needs a "remove DC bias" before running the effect.

  • RS: Started to fix this bug 04 Apr 2009
