Not if you use MP3 Direct Cut, which edits and changes the same file without
reencoding it, which is why I specifically specified MP3 direct cut. That
is one of the reasons some people use that program, so they can alter MP3
files without loss of quality.

I haven't looked for documentation, but I'm sure I can document that MP3
Direct cut allows for alterations with no quality loss..

I don't know what audio work you are looking for. I am an excellent

No offense intended Gene, and I don't want to spawn an audio discussion, but
had to address that. If you do anything other than cut an MP3 file--if you
equalize it, if you do some compression, if you do volume normalization or
balancing, or anything else that actually alters audio--and then save it as

another MP3 file, there will be a loss of quality. Especially if you do any

intermediate saves. MP3 is a lossy format, and any time you convert to 32
floating point PCM in order to work on it, which as far as I know all audio

editors do internally, and then save it back out, there is further loss
the down-conversion to MP3.

The only way to work on audio with no loss of quality (by work, I mean do
anything beyond cutting out sections which does not have to re-encode), is
work on the original wave files if available, but in any case to always save

intermediate steps in a native uncompressed format.
Every time you edit and re-save an MP3,, you are making a slightly more
copy of an already blurry copy. That is why exporting to MP3 is the very
absolute last step of any mastering operation.

Okay, that's drifting significantly, but I felt like it needed to be pointed
