New Features in Audacity 2.0

Audacity 2.0 is our current version. It has dozens of new features, developed in the 1.3 series. It replaces all previous versions, especially 1.2.6 and 1.3.14. See New Features in 1.3 for changes during the 1.3 series. See also Release Notes for more details.
Some of the major changes in 2.0.0 over 1.2.6 are:

    Many effects significantly improved, especially Equalization, Noise Removal and Normalize. Vocal Remover now included plus GVerb on Windows and Mac. VAMP analysis plug-ins now supported.
    Improved label tracks with Sync-Lock Tracks feature in the Tracks Menu. Multiple clips per track. Tracks and selections can be fully manipulated using the keyboard. Many more keyboard shortcuts.
    New Device Toolbar to manage inputs and outputs. Timer Record feature. New Mixer Board view with per-track VU meters.
    Automatic Crash Recovery in the event of abnormal program termination.
    Fast "On-Demand" import of WAV/AIFF files if read directly from source. FLAC now fully supported. Added support for optional FFmpeg library for import/export of AC3/M4A/WMA and import of audio from video files.
Update auf 2.03

Changes in v2.0.3:

    Uses libsoxr resampling library by default, instead of libresample, for higher quality and speed.
    Bugfix for Time Tracks and improvements
    New effects: "Studio Fade Out", "Adjustable Fade" and "Bass and Treble"

Changes in v2.0.2:

    Bugfix for JAWS screen-reader
    Bugfix for Normalize crash
    Bugfix for clicks on split lines
    Improved toolbars
    Enhanced some Nyquist effects

Changes in v2.0.1:

    New option to reset Preferences on next launch.
    Selection Toolbar: a value for the previous whole second displayed if the value was close to a whole second.
    Finding zero crossings could cause the selection to expand into white space at either side of the clip.
    Clips did not drag to another track if mouse was over a selection.
    Mixer Board: Rendering four tracks resulted in a redundant Track Strip followed by a crash.
    Imports, Exports and Files
    Exporting to WAV or AIFF led to a "Libsndfile says" error or corrupted output due to order of metadata in imported files.
    Bugfix for issues where normalization could be to wrong value if applied with DC offset correction, or if applied to "read-directly" WAV and AIFF files
    Sliding Time Scale: fixed an audible discontinuity at the beginning of the processed selection; fixed a serious quality problem on Linux 64-bit.
    Bugfix to prevent zooming with mouse wheel or ball scrolling the content off-screen.
    Shortcuts can now be added in Keyboard Preferences to items in the Generate, Effect or Analyze menus, including user-added plug-ins.
    Nyquist Effect plug-ins can now be added to Chains.
    New "Paulstretch" effect for extreme slowdown without pitch change.
    New "Sample Data Export" Analyze effect for exporting a file containing amplitude values for each sample in the selection.
    New Preference (off by default) to import files On-Demand (without seek ability) when using the optional FFmpeg library.
    New Preference (off by default) to retain labels when deleting a selection that snaps to the label without extending past it.
    CleanSpeech Mode (no longer supported)
    Added Serbian (Latin and Cyrillic) translations.
21 Oktober 2013: Audacity 2.0.5 Released

Audacity 2.0.5 replaces all previous versions. It fixes crashes or hangs that were reported in Audacity 2.0.4 on some machines, and contains many other bug fixes and stability improvements.

    (OS X) Crashes when importing audio files are fixed.
    (OS X) Files can now be opened using Finder "Open with", and by double-click or dragging to the Audacity icon.
    (OS X) Audio Unit plug-ins are not loaded until used. This makes Audacity start faster and avoids startup crashes due to incompatible plug-ins.
    (Windows) On a very few machines, the Windows WDM-KS low latency host caused Audacity 2.0.4 to hang or the computer to crash. WDM-KS has been removed from Audacity 2.0.5 while we work on safely enabling this host. WDM-KS will still be available for testing in the Windows alpha development builds.
    (Windows) Fixed a bug where Audacity would not record until the current input was reselected.
    (Linux) You can now navigate through an effect or other dialog using keyboard TAB.


is this version compatible with windows 7 64 bit?
update to 2.1.3

New features:

- Audacity 2.1.3 now properly supports Windows 10 (thanks to an upgrade of the PortAudio library) and on MacOS has some previously missing support for Magic Mouse/Trackpad (thanks to Paul Licameli).
- New Distortion effect, Rhythm Track (was called Click Track) and Sample Data Import (thanks to Steve Daulton). Also effects are no longer grayed-out when in pause.
- New scrub ruler and ‘pinned’ option so the waveform moves and the recording/playing head stays still. (Paul)
- New features in Timer Record (Mark Young & Steve)
- On Mac, is now added to /Applications/ directly rather than adding a folder there.

Changed in Audacity 2.2.0:

- 198 bugs/annoyances in 2.1.3 fixed, most importantly:
