See: https://manual.audacityteam.org/man/installing_and_updating_audacity_on_windows.html#winlame

and: https://manual.audacityteam.org/man/installing_and_updating_audacity_on_windows.html

And from the Manual:

The optional FFmpeg library allows Audacity to import and export a much larger range of audio formats including M4A (AAC), AC3, AMR (narrow band) and WMA and also to import audio from most video files. Because of software patents, Audacity cannot include the FFmpeg software or distribute it from its own websites.
