The Audacity Team have announced the release of beta version 1.3.3 of Audacity, which contains numerous new features and capabilities beyond the 1.3.2 (beta) release. Because it is a work in progress and does not yet come with complete documentation or translations into foreign languages, it is recommended for more advanced users. For all users, Audacity 1.2.6 is a stable release, complete and fully documented. You can have both Audacity 1.2.6 and 1.3.3 installed simultaneously.
