|Audacity 1.3.11 was available from 18th January 2010 until 31 March 2010 for Windows (2000, XP and Vista), Mac OS X and Linux. It was the recommended version for Windows 7, but full support remained provisional - see below for details. Audacity 1.3.7 was the latest available Beta version for Windows 98 and ME during this period.
These Release Notes describe:
|Notes for Windows:
Changes in 1.3.11
- Imports and Exports:
- Bug when exporting partial selections caused too much audio to be exported is fixed
- Fix corrupt files exported through FFmpeg when metadata included, (metadata is now exported correctly in M4A files)
- Prevent saving a new Audacity Project over an existing one as this could corrupt both projects
- Improved help for files that cannot be imported because the relevant optional library is missing
- Allow effects which change the length of the audio they work on to also be applied to selected label tracks, thus keeping them synchronized
- Fixed inability in Nyquist plug-ins to add labels to an existing label track
- (Mac) Equalization window was corrupted after Preview
- (Linux 64-bit) Fixed crash Generating Click Track
- Audio Devices:
- Fixed bug causing recording to stop short when the recording sample rate is not supported by the sound device and libsamplerate is used for resampling
- Fix crash when opening Preferences on a machine where there are no available audio devices
- Fixes for bugs using Timer Record and Sound Activated Recording
- User Interface:
- Sizes of some dialogues adjusted to ensure they fit on the screen
- Fix for supposedly "hidden" items appearing on screen with large monitors
- Various keyboard shortcut and translation fixes.
- Other bug fixes:
- Several timing-dependent crashes and minor incorrect behaviors have been fixed
- Windows installer now installs correctly over previous versions of Audacity
Changes and improvements
- (Windows) Better icon file with higher resolution and transparency
- New SoundFinder plug-in to label regions of audio between silences, so allowing silences between tracks to be excluded when exporting multiple
Known Issues at Release
- On-Demand WAV/AIFF import not available if using the optional FFmpeg importer (that is, if "FFmpeg-compatible files" set in the import dialog)
- (Windows) The Audacity executable cannot be added to the Explorer "Open With" menu if you have another version of Audacity also called "audacity.exe". You can set the file association to always use the Audacity Beta executable to open the required file type, but it will not appear in the list accessed by the "Open With" context menu item whilst there is another "audacity.exe" on the computer
- If a WAV/AIFF file is imported into a project using on-demand import, then the file is deleted whilst the project is still open, trying to play the project will cause Audacity to hang
- Album art and lyrics in imported metadata lost when exporting
- WAVEX (Microsoft) headers: GSM 6.10 files cannot be exported, and U-Law/A-Law files may not be playable.
- M4A: exports at 38000 Hz may not play properly (FFmpeg bug); M4A renamed to MOV will not play on Windows in iTunes or QuickTime
- WMA: no metadata is exported; this has been disabled because Windows cannot play the files if metadata is included (due to a current limitation in FFmpeg)
- Muting specific time-shifted mono tracks produces audio at wrong point on timeline in exported file if muted tracks are to left of unmuted
- Custom FFmpeg Export: Not all combinations of format, codec and options will produce a successful export. This is mainly or entirely due to limitations in FFmpeg, but currently Audacity lacks a warning that errors were encountered on export
- (Windows) Exported "Comments" ID3 tag not recognised by Windows Media Player or Explorer
- Genre WAV info tag (IGNR) not supported due to limitation in libsndfile.
- It is currently possible to attempt simultaneous imports or exports by using shortcuts (or File > New on Mac): Audacity is not yet capable of running these simultaneous operations safely, and attempting this may crash your project.
- Effects and Analysis:
- Truncate Silence may not give intuitive results on multiple tracks.
- Nyquist effects join separate clips together
- LADSPA Multiband EQ (optional download) may not be visible in the Effect menu, or may crash in use
- Label tracks:
- Typing "j" or "k" in a label may activate the "move cursor" shortcut instead
- After adding a label at the playback position and confirming with ENTER, using an unmodified shortcut to stop or pause will not do so, but will write a label at the cursor position. Workaround: use up arrow instead of ENTER to confirm the label.
- Mixer Board:
- The meter range does not reflect a change in the dB range meter preferences until restart
- The following may not read correctly in screen readers: Labels, cells in Label Editor, time values in Generate effects, accelerators in Preferences, Metadata Editor(JAWS 11)
- If playback scrolls, cursor jumps to start of scroll on stop, hiding previously visible audio preceding the playback position
- Not all menu items correctly enabled when the preference: "Select all audio in project, if none selected" is checked
- A few interface elements do not change correctly after a language change until restart
- If you add an external audio device while Audacity is open, you must restart Audacity to enable it to recognise that device
- Calculation of "disk space remains for recording (time)" incorrect when recording in 24-bit quality. You may record for 50% longer than the indicated time
- Automatic Crash Recovery disregards track zoom level and position
- Projects created by Audacity 1.1.x or earlier are no longer supported. Workaround: Export each project track as WAV using the appropriate legacy version of Audacity, then import the WAV files into current Audacity
- It is no longer possible to use Save Project or Save Project As to overwrite another pre-existing project, even if that project is not in use. Functionality to overwrite a project not in use will be restored in a future version of Audacity when we are sure it will always be safe.
- Audacity can import, display and cut/copy/paste MIDI files, then export them, but they cannot be played; undoing an edit with a MIDI track open causes the MIDI data to be lost in Windows builds
|Please write to feedback_AT_audacityteam_DOT_org if you experience any of the following known but not fully understood issues, giving us steps to reproduce them so they can be fixed. |
For items marked ¶, some work has already been done which may have eliminated the issue - your help with testing these issues is especially welcome.
- (Windows XP) The input slider and selector for inbuilt devices are unavailable if a USB device is also connected
- (Windows 7) On launching Audacity, "Runtime Error Program:(location) R6034" occurs. Workaround: Right-click over audacity.exe, click Properties and change compatibility mode to Vista SP2 or XP SP3.
- (Windows) Visible scanning dialogue appears on every launch of Audacity when no VST plug-ins are present
- (Windows) On Vista and 7, input sources such as microphone and line-in must be selected in the Audacity Audio I/O Preferences, not the Mixer Toolbar input selector.
- (Windows) Timer Record cannot maintain scheduled duration if system clock changes.
- (Windows) Audacity is incompatible with some professional sound cards and may crash if one of these cards is the default when you open Audacity. Workaround: Make a different sound card your default when using Audacity, but please let us know if this affects you so we can track down and solve the problem.
- (Mac OS X) Very occasionally, users may find that recording causes "error opening sound device", or that after running Audacity, other media players don't produce any sound, or crash: to resolve this, set up your sound device in Apple Audio MIDI Setup to work in stereo, 16-bit, with a sample rate of 44100 Hz or 48000 Hz, and set the sample format and rate identically in Audacity. More help here
- (Mac OS X) If using Audacity when the "Hear" audio plug-in is running (or has been since boot), there will be excessive memory usage which could cause a crash: appears to be due to buggy memory allocation in "Hear".
- (Linux) If Audacity is left open but without focus, its CPU use will rise slowly until all available the system CPU is consumed. This is a bug in wxGTK 2.8.10 (not previous versions) which will be fixed in wxGTK 2.8.11. For Package Maintaners / Distributors: The upstream change in wxGTK is simple and can easily be patched into wxGTK 2.8.10 if desired: Grab the changeset, run it through dos2unix (as it seems to come with dos line-endings), and apply it to the wxGTK 2.8.10 sources (with -p3 to get the paths right if you patch from the top level of the tarball distribution).
- (Linux) Effects and other dialogues do not have focus on opening. This is a bug in wxGTK for which there is no current workaround. Click in the dialogue to navigate it and change parameters.
- (Linux) Audacity now supports interfacing with JACK, but this has not been tested, and has a number of known reliability and usability issues: patches to improve both will be welcomed.
- (Linux) Custom FFmpeg Export dialogue does not respond to ENTER after clicking in the Formats or Codec selector.
