Audacity 2.1.2 Has Been Released

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 2.1.2, which has been recently released, coming with changes and bug-fixes.

  • Effects
    • Noise Reduction defaults changed.
  • Interface
We’ve made several improvements to the spectrogram view of tracks which are particularly valuable for vocal work.

  • New option ‘Spectral Reassignment’. This algorithm deduces a ‘finer’ spectrogram for vocal work.
  • Four new Spectrogram scales.
  • Improvement to the Pitch (EAC) algorithm – cleaner (sharper) display.
  • Spectrogram Settings are now available per-track.
  • Other Changes
    • Upgraded from wxWidgets 2.8.12 to wxWidgets 3.0.2.
    • Restructuring of the Preferences Menu
    • Restructuring of the Track Dropdown Menu (for the Spectrograms)
    • The Noise Reduction “Frequency smoothing” default has been increased to 3 to help avoid metallic artifacts. Resetting Preferences or deleting audacity.cfg will set the new default.
