Jump to: navigation, search

Audacity 1.3.12 was available from 1st April 2010 until 10th April 2011 for Windows, Mac OS X and Linux. It was the recommended version for Windows 7, but full support remained provisional until 1.3.13 - see below for details.

These Release Notes describe:

  • Changes to 1.3.12 Beta as compared with 1.3.11
  • Issues with 1.3.12 Beta which were known at time of release

Warning icon Notes for Windows:
  • MP3 export from Audacity 1.3.7 and later requires the latest version of the LAME encoder
  • The Windows installer will not replace 1.2.x installations, but will install alongside them

Items struck out have been fixed in the latest development code, meaning that if you compile Audacity yourself from that code these issues should not occur.

Changes in 1.3.12

Bug fixes

  • Imports and Exports:
    • AAC files could not be exported at 48000 Hz
    • When importing multiple native file formats using FFmpeg, all files after the first reverted to using the native importer
    • FFmpeg custom export window too large on 800 x 600 resolution monitors
    • Projects froze if files imported via On-Demand were no longer available
    • (Linux) WAV/AIFF exports were corrupted if overwriting an aliased file which had been imported using the command line

    • Cutting or deleting a region in the waveform and label track did not move the labels in advance of the cut
    • Incorrect behavior snapping to labels and boundaries with Snap To enabled
    • Labels can now be reversed if included with the audio selection
  • Other:
    • When using non-English languages, Generate effects truncated the selected region
    • Mice with high-precision scroll-wheels could cause a crash
    • Changing recording preferences using the Transport menu did not update the menu in other open projects
    • (Windows 7) Clicking in a file open or save dialog caused files or folders to disappear from the list, and file filtering was broken

Known Issues at Release

Categorised bugs

  • Imports:
    • Even if the file filter in the File Open or Import window is set to "FFmpeg-compatible files", native formats like WAV or MP3 still import using the native importer when using File > Recent Files, dragging in or opening from a file manager program
    • On-Demand WAV/AIFF import is not available if using the optional FFmpeg importer (that is, if "FFmpeg-compatible files" set in the import dialog)
    • 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, the track plays silently with no warning about not being able to read the file
    • (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
    • (Mac) Files imported from iTunes may create invalid characters in the .aup project file, which will cause an error at a stated line when re-opening the .aup file. Workaround:: open the .aup file in a text editor and in the affected lines, remove everything except a to z characters and whole numbers between the quotes in value=""
  • Exports:
    • 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)
    • Custom FFmpeg Export: many combinations of formats and codecs are incompatible, as are some combinations of general options and codecs. Some files may be exported as zero kb files.
    • Muting specific time-shifted mono tracks produces audio at wrong point on timeline in exported file if muted tracks are to left of unmuted
    • (Windows) Exported "Comments" ID3 tag not recognized by Windows Media Player or Explorer
  • The optional FFmpeg library is not automatically detected after installation. Before importing or exporting using FFmpeg, you will need to go the Libraries tab of Preferences and click "Locate" in order to detect the installed library.
  • 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
  • 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
  • Effects and Analysis:
    • Built-in Generate effects may create additional unwanted split lines if generated inside an existing clip
    • Truncate Silence does not adjust clip boundaries inside the selection being truncated
    • 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
    • (Windows) On a few Windows XP or 2000 machines, the background of the Frequency Analysis graph is reported to be completely transparent, and new spectrum plots are drawn underneath previous plots
    • (Windows) VST plug-ins are not detected in the registry VSTPluginsPath or in C:\Program Files\Steinberg\VSTPlugins
    • (Windows) Visible scanning dialog may appear on every launch of Audacity when no VST plug-ins are present
  • Playback and Recording:
    • If you add an external audio device while Audacity is open, you must restart Audacity to enable it to recognize that device
    • Play-at-Speed slider: Change of playback speed is no longer automatic after you move the play-at-speed slider. To change speed, move the slider, then click the green button to left of the slider to play at the new speed.
    • If playback scrolls, cursor jumps to start of scroll on stop, hiding previously visible audio preceding the playback position
    • 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.
    • (Windows Vista and 7) input sources such as microphone and line-in must be selected in the Audacity Devices Preferences, not the Mixer Toolbar input selector
    • (Windows Vista) If you change the input volume in Audacity and then record, the volume is reset to its original level
    • (Windows XP) The input slider and selector for inbuilt devices are unavailable if a USB device is also connected
    • (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.
    • (Linux) Audacity now supports interfacing with JACK, but this has not been fully tested, and has a number of known reliability and usability issues: patches to improve both will be welcomed
  • Mixer Board:
    • The meter range does not reflect a change in the dB range meter preferences until restart
  • Interface:
    • Entering a backslash "\" in a file name when using File > Save Project gives a "not writable or disk full" error, after which the menu item cannot access the save dialog. Workaround: Use File > Save Project As to enter another legal character.
    • Dependencies dialog shows no warning if listed files no longer exist, and may give a false "self-contained" indication if a longer waveform has been edited down to a short selection
    • Not all menu items are 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
    • Automatic Crash Recovery disregards track zoom level and position
    • (Windows, Linux) File > Close performed on the last window does not by default clear to an empty workspace. This ability can be enabled in the Interface preferences, but then ALT + F4, window [X], Taskbar close and system shutdown will not quit the application on closing the last window. Only File > Exit will do so.
    • (Linux) If Audacity is left open but without focus, its CPU use will rise slowly until all available 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. See
      • For Package Maintainers / 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) The OK button has focus on opening effects and other dialogs, instead of fields for changing values. This is a bug in wxGTK. To navigate the dialog, tab into it or click in it.
    • (Linux) Custom FFmpeg Export dialog does not respond to ENTER after clicking in the Formats or Codecs selector
  • Label tracks:
    • 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.
    • (Linux) In projects containing several hundred labels or more, Audacity may appear to freeze on 100% CPU when performing effects or other actions. Workaround: Since this problem may affect only the first label track in a project, you can add an empty first label track and then work on a second one.
    • (Linux) Typing in a label while playing draws temporary spurious lines at the playback position
  • Accessibility:
    • 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)
    • Toolbar buttons cannot be clicked on by using ENTER on the keyboard: ENTER navigates to the next button instead
  • Projects:
    • 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.
    • 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.

Bugs requiring more investigation

Please write to our feedback address 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.

  • Projects do not reopen properly with "orphaned" or "missing" blockfiles or "duplicate attribute" errors
  • Projects do not re-open properly from the Automatic Crash Recovery dialog
  • Projects crash when applying repeated effects towards the end of audio tracks^
  • Typing "j" or "k" in a label may activate the "move cursor" shortcut instead
  • WAV or AIFF files freeze or crash Audacity on import
  • (Windows XP, reported on) Clicks during recording
  • (Windows) Timer Record unreliable with recordings starting before and ending after midnight
  • (Windows) On Vista and 7, and on XP with some USB devices, the Audacity input/output level sliders act independently of/incorrectly with system level sliders. The achieved recorded level may only match the level indicated on the Recording VU meter if the Audacity input slider is at 100%.^
  • (Windows) Effects processing/waveform rendering after completion may be much slower than Audacity Beta 1.3.8
  • (Mac OS X 10.5.8 PPC) Hang when scanning for VST effects on first install of Audacity Beta. Workaround: rename the system VST folders /Library/Audio/Plug-ins/VST or ~/Library/Audio/Plug-ins/VST
  • (Linux) 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

Miscellaneous platform-specific issues

  • (Windows 7) On launching Audacity, "Runtime Error Program:(location) R6034" occurs. Workaround: Right-click over audacity.exe > Properties and change compatibility mode to Vista SP2 or XP SP3.
  • (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 at:
  • (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"
