Audacity Development Team - (Open Source)
Audacity is a multi-track recorder able to handle full projects, and an audio editor.
Audacity is a free audio processing software that supports the following file formats: WAV, AIFF, OGG and MP3, applying many filters to sound: silence suppression, echo or add special effects, noise suppression, mixing, distortion, reverb, pitch bend / shift and more.
It can cut audio files, delete or add rests, apply fading in / out audio files and treat separately the left / right channels. The program offers unlimited undo number and also the possibility to convert the records and old tapes to digital media.
Thanks to the integrated editor, you also have the ability to copy, paste and mix sounds together to create multitrack projects.
# Bug fixes:
- "Retain labels" Interface Preference did not retain labels for a region that snapped exactly to both label edges.
- Projects did not save the track selected state.
- (OS X, Linux) Timer Record: Interlinking of the Start, End and Duration controls was broken.
- (Windows) JAWS screen-reader did not read the "Draw curves" and "Graphic EQ" radio buttons in Equalization correctly. .
* Envelopes and Clips:
- Exporting (or any render operation) on a track containing split lines could create clicks at the split lines.
* Effects and Analysis:
- Normalize could crash if the track name contained "%".
# Changes and Improvements:
* Duration controls when generating at a point now default to hh:mm:ss + milliseconds format. Selection Toolbar also defaults to that format on first installation or resetting preferences.
* Toolbars visual improvements:
- "Snap To" in Selection Toolbar now has an explanatory tooltip.
- Device Toolbar tooltips now display the selected device.
- Increased default width of Device Toolbar and Meter Toolbar.
* Improvements and some bug fixes to Nyquist effects, including:
- Delay (new option to prevent duration change)
- Sample Data Export (new "L-R on Same Line" layout option)
- Risset Drum (new "Amplitude" slider).
* Importing a labels file writes the file name to the name of the Label Track, and exporting a labels file offers the name of the last Label Track in the project.
* Removed the "Audio cache" option from Directories Preferences due to frequent crash reports. All data operations will now be written to disk and not to RAM.
* Removed the FFmpeg "On-Demand" option from Libraries Preferences (this fixes Audacity not building if configured --without-ffmpeg).
* Compilation: Progress on making the Modules feature mainstream. Modules can now be individually enabled and disabled in Preferences.
