Hello Linux Geeksters. As you may know Audacity is an open-source, multi-platform audio editor and recorder, running on Linux, Windows and Mac OS X.
Main features:
- recording (from a microphone or mixer)
- import/export of WAV, AIFF, AU, FLAC, MP3 (via LAME encoder) Ogg Vorbis files
- advanced editing (cut, copy, paste, delete commands with unlimited “Undo” and “Redo”, multitrack mixing)
- digital effects (change the pitch, remove background noises, alter frequencies, remove vocals, create voice-overs for podcasts etc.) and plug-ins (support for LADSPA, Nyquist, VST Audio Unit, including VAMP analysis plug-ins).
The latest version available is Audacity 2.1.0, which has been recently released, coming with changes and bug-fixes.
Effects:
- LADSPA, VST and Audio Unit (OS X) effects now support real-time preview, save/load of user presets and saving effect settings across sessions. Note: Real-time preview does not yet support latency compensation.
- VST effects now support import/export of FXB preset banks.
- Shell VST effects that host multiple plugins are now supported.
- All Effect Menu items (built-in or plugin) can now be used in a Chain.
- Items in the Effect, Generate or Analyze Menus can be sorted or grouped by name, publisher or class of effect.
- Noise Removal is improved and renamed to “Noise Reduction”.
- Change Speed has new time controls for current and new length. You can now enter the speed change as a multiplier e.g. “2” is twice as fast.
- New “Crossfade Tracks” effect can be used for crossfading two tracks. This replaces Cross Fade In and Cross Fade Out.
- Nyquist Prompt and most shipped Nyquist effects now have Preview button.
Interface:
- Redesigned Meter Toolbars: The default shows separate Record and Playback Meters, half-height so they can be wider while docked, in gradient style.
- A frequency selection can now be made (and spectral edit effects applied to those frequencies) when in a spectrogram view. You can also create or adjust frequency selections in a new “Spectral Selection Toolbar” (available at View > Toolbars).
- Transcription Toolbar (Play-at-speed) can now loop play and cut-preview.
- Timer Record now saves recordings automatically into an existing project.
- New Armenian translation.
