If the original M4A is high enough quality and you convert to a
high- resolution you might not notice the difference. If you're
going to be editing the files you should consider converting the
M4A to WAV format, doing all your editing in that domain, then
converting them to MP3 as the very last stage.

I am not sure how that changes anything. It is still the
equivalent to an analog "copy of a copy".

It makes a difference if you do multiple edits and save your work in
the interim. If you were working on the original compressed file you'd
be recompressing it each save. Doing all those edits on the WAV file
avoids that.

I think most serious editors do that because it takes a whole lot
longer to "load" than simply to copy the MP3. (Based on Sound Forge)
If you save as WAV it is almost instant. Any other format chugs along.
