Features This is a list of features in Audacity, the free audio editor. For more information on how to use these features, go to the help pages. Recording Audacity can record live audio through a microphone or mixer, or digitize recordings from cassette tapes, vinyl records, or minidiscs. With some sound cards, it can also capture streaming audio. * Record from microphone, line input, or other sources. * Dub over existing tracks to create multi-track recordings. * Record up to 16 channels at once (requires multi-channel hardware). * Level meters can monitor volume levels before, during, and after recording.

Export your recordings in several common file formats. * Import and export WAV, AIFF, AU, and Ogg Vorbis files. * Import MPEG audio (including MP2 and MP3 files) with libmad. * Export MP3s with the optional LAME encoder library. * Create WAV or AIFF files suitable for burning to CD. * Import and export all file formats supported by libsndfile. * Open raw (headerless) audio files using the “Import Raw” command. * Note: Audacity does not currently support WMA, AAC, or most other proprietary or restricted file formats.

Changes Since Previous Version Bug fixes Keyboard Preferences: Shortcuts for Generators, Effects and Analyzers were not exported. All imported shortcut changes were discarded. Equalization curves were corrupted in Graphic EQ mode after switching to/from Draw Curves or after running the effect then reopening it. Change Pitch displayed corrupted values when reducing pitch or editing "from" Frequency. Detection was very inaccurate at high sample rates. Bass Boost no longer clips if the track contains 32-bit audio. Auto Duck was excessively slow on older machines. (Windows) Exported MP3 comments tags were not seen by Windows programs. (Windows and OS X) Audacity crashed if you used system quit before file import was complete. (Linux) Equalization crashed Audacity if the XML file was corrupted. (Linux) When configuring effect parameters in "Edit Chains", "Preview" (not intended to be functional) caused a crash. (Linux) LICENSE.txt and README.txt were wrongly installed in /usr/local/share/doc instead of /usr/local/share/doc/audacity/ . Accessibility: ENTER did not toggle selectedness of a label track unless a label was selected. Numerous other interface fixes. Changes since version 2.0.4: Bug fixes for: * Shaped dither was corrupted and too loud on all stereo exports except FLAC. * Keyboard Preferences: some Edit and Align commands for different sub-menus showed the same name. * Recordings stopped with "Stop and Set Cursor" shortcut could not be undone. * In locales that use comma for decimal separator: * Text boxes with slider in Nyquist effects only produced whole numbers when using comma to enter a fractional number. Text boxes without slider still have this problem. * Built-in generators produced silence after running a Nyquist effect. * (Windows) When first changing to Windows WASAPI host, the input volume slider in Mixer Toolbar was enabled when it should have been permanently disabled. * (Windows) On some machines, launching Audacity then recording from the current Device Toolbar input would not record until the input was reselected. * (OS X) Frequent crashes occurred on importing audio files on some machines. * (OS X) Files did not open using Finder "Open with", double-clicking the file or dragging the file to the Audacity icon. * (Linux 64-bit) Fixed a crash when using Equalization. * (Linux) It was not possible to open an effect or other dialog then navigate through the dialog using TAB. * (Linux) The Play shortcut did not play a read-directly WAV, AIFF or FLAC import if the warning for importing uncompressed files appeared. Changes and Improvements: * Tracks Menu: * The separate commands that aligned track start or end with the cursor or with selection start are combined into "Cursor/Selection Start" commands. * "Align and Move Cursor" renamed to "Move Selection when Aligning". * Label Tracks: * Labels Editor now allows empty labels to be saved on closing the editor. * TAB and SHIFT+TAB when the label track has focus now always move forwards or backwards respectively to the nearest label. * (Windows) On a very few machines, the Windows WDM-KS low latency audio host introduced in Audacity 2.0.4 caused Audacity to hang or the computer to crash. WDM-KS has been removed from 2.0.5 until it can be safely enabled. * (Windows and OS X) Screen reader improvements for Install VST Effects dialog. * (OS X) Audio Unit plug-ins detected by Audacity on launch are now not loaded until chosen from the Effect menu. This should speed up launch and avoid crashes at launch due to misbehaving Audio Units. * (Linux) Update to PortAudio r1910 fixes memory and other bugs under ALSA. * (Linux) Applied fix for wxGTK 2.8.12 bug which resulted in loss of Audacity's menu bar (or visual corruption under Unity) on Debian-based systems.
