Re: "Perfect" MP3 fails to import

Good detective work James.

Any ideas about the MP3 file (first post of this thread)? Given your
explanation of the OGG problem, I assume that it is a different issue.

I'm thinking that it is probably an Audacity bug because the file appears
to be a valid MP3 file. On the other hand, if the MP3 is malformed (in some
way that I've not been able to detect), then it's rather more open to
opinion whether or not it is an Audacity bug, or a bug in the application
that created it.
