So you're saying that MP3s are encoded using deltas *between*
channels, as well as within each channel? Never thought of it that
way, but it makes sense.

No no no, M-S encoding is one of the options, strict X-Y encoding of high
range (discarding ramdom phase between channels) another, that one kills
real ambience.

Still, would it really be any more lossy than doing any kind of
editing and re-saving on a MP3 file?

I wouldn't worry too much on the second encode if say max quality variable
bandwidth ms-encode was the initial choice. It is also possible to select
encode as fully independent channels, but that is an unlikely initial
choice.

Kind regards
