Install AudaCity Sound Editor on Ubuntu 11.10/any Ubuntu version/Linux Mint

Audacity is free, open source software for recording and editing sounds. It is available for Mac OS X, Microsoft Windows, GNU/Linux, and other operating systems.

Changes and Improvements:

• Normalize now preserves left-right balance in stereo tracks by default with an option to normalize stereo channels independently.
• Spectrograms now allow window sizes up to 32768 and frequencies up to half the sample rate (the maximum possible).
• Mix and Render now preserves clip length by not rendering white space before the start of audio, and preserves audio before time zero.
• CleanSpeech Mode has been removed from Preferences but can be run or disabled in 1.3.14 by changing Preferences in a previous Audacity version.
• (OS X) Added support for AudioUnit MusicEffects (but no MIDI support).

To install on Ubuntu/Linux Mint open Terminal (Press Ctrl+Alt+T) and copy the following commands in the Terminal:

• sudo add-apt-repository ppa:ferramroberto/oneiric
