Thanks for the tip! Hmm... that was a tricky one. I'd suggest that this information be included in the download page, because one has the impression that just installing the FFmpeg libs would automatically enable them.

Well, there are two different issues here (and all Beta documentation is "unfinished" by definition)... at the moment FFmpeg is not detected automatically as LAME is - the first time you use FFmpeg to import or export, you have to use the "Locate..." button in the Import / Export Preferences. Probably this should be in this particular FAQ, but we are hoping to enable automatic detection of FFmpeg in future if FFmpeg is installed to its default location.

Once located, FFmpeg will automatically be used for files like WMA that only FFmpeg supports. Forcing import via FFmpeg of formats which are supported natively by Audacity is a fringe case, but it is covered in the draft Manual:

None of the other MP3 files reported to us which import incorrectly via LIBMAD have CD TOC frames, so there is some other problem in those cases.

We've now fixed this in source code - the problem occurred where any of the ID3v2 tags (Music CD Identifier or whatever they were) were placed right at the front of the file. The fix will be in the next 1.3.8 release, but if you want to try it now, grab this:
