The following libraries listed are used in Saucedacity with the following applied patches. This information is taken from lib-src/audacity-patches.txt.

Note: it is likely that "submodulizing" these libraries will result in any previously applied Audacity patches being dropped. We cannot find these patches, meaning that we will have to use vanilla versions of these libraries (or "re-create" them where need be).

This page is a work in progress. There might be some errors
