Issues related to Microsoft Windows are reported here.
- Check the FAQ first: http://audacity.sourceforge.net/help/faq
- See if the question has been answered by email before in the mailing list archive.
- If you want support with a specific bug then contact the audacity support mailing list at [email protected]
- Feature requests go on the FeatureRequests page
Known bugs: The following bugs are known in audacity 1.2.3:
- MP3 export at sample rates other than 44100Hz may not work or result in an MP3 that is unplayable. Set the Project Rate to 44100Hz before exporting if you have difficulties.
- The equaliser / FFT filter effects may introduce pre-echo or distortion.
- The "Apply gain after compressing" option to the compressor may cause clipping with some signals. Turn it off and use Amplify or Normalise afterwards to restore the level.
Unconfirmed bug reports:
Version 1.2.3 - - I have been having a repeated crash problem for the last week or so--every time I use a fade, compress, or amplify effect the program "encounters a problem and needs to close." I'm thinking that this may be related to a windows update that was installed a few weeks ago...not sure. It only seems to happen with my high-gain recordings, not low-gain ones.
Version 1.2.3 - - I record from line in, i cut the sound document in two parts (cut and paste in a new audacity instance). Then I start save as mp3 with the first and as it is saving I do save as mp3 with the second file to prepare de id3 tags. When i do this i block the saving of the first file and as i cancel the save as mp3 operation with the second file the two instances of audacity close and i loose all. Now i have to try to recover the temp files
Version 1.2.3 - - Sometimes when a clip is copied from one stereo track into another stereo track, Audacity freezes and crashes.
Version 1.2.3 - - After opening about 20 wav files (10 at a time) and converting them to mp3's it tells me it must shut down. Upon re-opening it asks to delete temp files. Even after clicking "yes" it only opens 2 or 3 before I get the same error box. This happens a couple of times until it won't open ANY files. Re-booting the computer starts the process all over again.
Version 1.2.3 - - MAJOR BUG! Audacity thinks that ALL wav files in the TEMP directory are Audacity temporary files and will offer to delete them upon startup. If you do this, the files will not be recoverable from the Recycle Bin. Be especially cautious if you use a working temp directory for multiple purposes. The audacity temp directory, like most program temp directories, in not meant to be shared as the program will delete and create many files there. Wiping everything (often without prompting) is considered normal for program temp directories.
Version 1.2.3 - - When changing spectrum display maximum frequency, top frequency on scale changes, but spectrogram is not redrawn to reflect the change. -Also true for FFT size setting.
Version 1.2.3 - - OK/Cancel buttons in Audacity's dialogs are switched from the Windows convention: OK should be on the left, and Cancel on the right. Parts of Audacity that use the Windows message box /do/ have OK on the left, which leads to confusion.
Version 1.2.3 - - If a WAV file is exported to a drive that doesn't have enough space, a valid WAV file is produced without error, but the WAV file is truncated - it only contains as much audio as could fit on disk.
Version 1.2.3 -- Edit half of a large audio file (normalize/envelope), save the project and close the program. When the project and associated files are moved to a different machine the unedited parts of the file display as wave forms just fine, but play as silence. Any attempt to alter the audio in these junks also results in silence.
Version 1.2.3 -- Additional details on previous posting: I'm facing the same issues with a long file, over 74 minutes, though I don't believe the files have been moved from their original location. I'm helping an 81 year old Chinese friend make some recordings and she is doing the editing herself with a great deal of help over the phone and through NetMeeting . I'm not able to explain to her how to trouble shoot this, but here are some questions I hope you all can help us with.
1. Should the *.au files and *.auf files in the project's filename_data directory be equal in number, or be some ratio? I wonder whether some data files have been misplaced. No - there will be a .au file for each section of audio actually stored in audacity (record by audacity or processed there), and a .auf file for each 10 second chunk of uncompressed files linked to the project. See the quick reference for details of how uncompressed files like WAV are imported.
2. I too can see the waveforms of the missing audio, and it appears to be correct according to what I know should be there to match her speech. I've had her burn a DVD of the project files (*.aup, *.wav and *.aup.bak, but not the data directory) and mail it to me. I still see the waveforms on the DVD, but hear nothing in some parts. I've tried copying the files to a new location on her machine, and could not see the waveforms for the missing audio in the new copy, and now I no longer see the waveforms on the original copy. Any ideas here? You have the .aup file, which contains the wavefrom preview information, but not the actual data (in the .au and wav files) needed to play the audio or re-draw the waveform. When you do the copy the waveform is re-drawn, and so the (correct) flat line is drawn.
3. I could zoom in on the waveforms that were missing the corresponding audio and they seemed correct still even zoomed in a good ways. I've tried copying the waveform of a silent portion (that should have sound) to paste it into a new project; I get an error stating that a .au file could not be found. I checked in the filename_data directory and sure enough, that file is missing. I'll try to recover it from my friend's computer, I doubt she's deleted it, and if she has, I'm sure she hasn't cleared the recycle bin. More to come, please comment here if you have any ideas on this issue. If you are running a version prior to 1.2.3, then there is a bug which can cause loss of data from the project. Make sure you upgrade to the current version. For more reliable responses to individual queries check the mailing list archive or contact the [[email protected] mailing list]
WIN 2000 Section
Version 1.20 - 1.22
version 1.2.2 - autoscroll wrapping problem still present - after recording in mono 44.100Hz (normal zoom) for at least > 1 hour 50+ minutes, The autoscroll wrapped to the 16 minutes position (not sure exactly when it wrapped around). The recording continues and appears to be still recording correctly, but the autoscroll display is incorrect. When that happens you can't use the horizontal scrollbar to move to the end of recording whilst recording and autoscrolling. Once you click stop, you can use the horizontal scrollbar to move to the end. Maybe a number is overflowing and wrapping - maybe should turn on warnings for overflows till such problems are resolved? So far this doesn't appear to happen with the old version (1.0.0), or at least it's not common.
Mouse wheel doesn't appear to zoom in or out. (It works if you hold down the Ctrl key.) Intentional to match other apps. This is what is listed on the Mouse tab of the preferences.
Better plugin selection organization (perhaps submenus). Feature request. This is done in 1.2.4
Make Default filetype 'Audio Files(.wav,.mp3,.aif,.aup,.ogg,.vox)' instead of '*.*', (but don't remove '*.*')
Allow for dragging beat marker
Naming beat marker key creates garbage characters(on laptop, arrow keys, inset, home, end, delete, F1, etc.). Just don't register these keys. Left & right key, home, delete should work. Up key can = home and down = end. These are FeatureRequests and belong there Export type depends on file extension instead of the three export types crowding the file pulldown menu. When playing instead of having the cursor jump from page to page, use smoother transition such as center cursor. Allow for slowdown of playback for editing purposes Zoom percentage dropdown selection
VCD sound(MP3?) not good, worked fine on GoldWave VCD sound is Mpeg I Layer II, and multiplexed with the video in a single stream. You need to demux the streams before opening the audio-only stream with audacity. Try tmpeg for demuxing.
Allow editing even if not zoomed in thus modifing larger portions of sound
- this should work, except the draw pencil which only works when you can see the samples you are moving.
Too much lag during drawing most likely due to disk access. Use memory instead of disk and then commit changes?
Allow markers on timeline or make use of timeline somehow.
Freezes on startup with SB Live! Audio [DF80] sound device enabled (EMU10K1 Audio Processor)
- this should be fixed in more recent releases, providing the drivers are correctly installed.
Allow bookmarks to be created while recording Done in 1.2.4 - CTRL + M
When saving as a (short) WAV file, sometimes creates a lot of silence at the end of the saved track
Export selection as WAV - files generated by http://www.naturalvoices.att.com/demos/, when saved using "export selection as WAV", are rounded up to the nearest 5 seconds
No ability to turn off warnings about "saving this file" - when you're editing 100 small files, it would be nice not to click a dialog-box each time (especially if you've just saved as a "real" file format)
The preferences dialog box has a windows-style tab bar, which often appears in its rightmost position, looking as if there are only two tabs available (unless you happen to know that there's the left/right arrow which scrolls the tab-bar headings ?!?)
