Just keeps getting better - the Audacity team has released another update to their popular cross-platform, open source digital audio editing application. The Audacity 1.3.x beta line features a ton of options that aren’t available in the 1.2.x stable versions. For example, it’s much easier to move sound files from one track to another or to split and manipulate audio tracks.

Audacity 1.3.4 beta features a ton of small, but important updates, including:
A new welcome screen
Enhanced Windows Shell integration, meaning you should be able to access Audacity from Windows dialogs like “open with.”
New keyboard commands and shortcuts
The solo track button actually does what you’d expect and mutes all other tracks
Metadata editor added for OGG, FLAC, and WAV/AIFF exports

As usual, Audacity 1.3.4 beta is available for Linux and Windows platforms, though for OS X is still 1.3.3 beta. More info here can be found here.
