Audacity 3.0 Digital Audio Editor Released With New File Format
Audacity 3.0 is a big update over the Audacity 2.4 series in that it overhauls its project file format. Rather than the pile-of-files approach for managing assets being dealt with inside an Audacity project, the new "AUP3" file format will store all project elements within that single file.
This fundamental change should lead to less confusion by users over what file(s) are needed for a given project as the prior AUP file format led to confusion by some and the loss of their audio assets. AUP3 is leveraging an SQLite database for storing everything. With the single project file approach, there may be some minor performance benefits too.
Besides the shift to the AUP3 format, Audacity 3.0 also has a number of tweaks, more than 160 bug fixes, and other improvements. Some of the bigger work items were shifted off though of Audacity 3.0 in order to focus on the fundamental change around the file format.
