Versie 2.0 van de opensource-audio-editor Audacity is uitgekomen. Het programma, dat beschikbaar is voor Windows, Linux en Mac OS X, kan geluid opnemen, en wav-, aiff-, ogg- en mp3-bestanden importeren en exporteren. Het heeft een ongelimiteerde undo-functie en heeft daarnaast een grote verzameling effecten aan boord, zoals fade-in en fade-out, echo, tempowijziging en ruisonderdrukking. Meer effecten kunnen eenvoudig worden toegevoegd, want het programma ondersteunt zowel vst- als ladspa-plug-ins. Het changelog van deze release laat de volgende veranderingen zien:
New features
- 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.
Changes and Improvements
- New Interface preference to show the track name in the display (this is off by default).
- Longer default Playback preference for effects preview and preview before cut.
- Restored use of Page Up and Page Down to scroll horizontally.
Bug fixes
InterfaceImports and Exports
- Fixed playback speed and synchronization problems when dragging clips or tracks between tracks having different sample rates.
- (Windows) Removed a crash risk where shortcuts could be used to record or import in one project while importing or exporting in another.
Effects and Analysis
- Fixed crashes when changing the sample format of read-directly WAV or AIFF files using the Track Drop-Down Menu.
- Fixed a crash importing MP3 files that had duplicate metadata tags (this is a bug in current libsndfile which has been patched in Audacity; MP3 files mislabeled as WAV which have duplicate tags will still crash Audacity on Linux if Audacity has been compiled against an affected version of system libsndfile).
- Fixed an issue where excessively high or corrupted sample values in the audio could corrupt exports from the start of the problem for the rest of the file, and could corrupt the rest of the project.
- (Linux) Fixed Audacity could not be compiled against FFmpeg 0.7.x and 0.8.x.
- Fixed crash on launch when using "Ambisonic Decoders (PC)" VST plug-ins and other plug-ins that enable additional floating point exceptions.
- Fixed Plot Spectrum background could be transparent on some machines.
- Bug fixes for Click Track, High Pass, Low Pass and Vocal Remover.
- Chirp, Tone and Silence generators now remember their settings.
