not with [readsf~] (if you care about micky-mouse voices).
but then, you cannot read mp3's with [readsf~] either.

and you could change Pd's sampelrate to 22050.

and you could convert your 22.5kHz mono wav-file to mp3 (or 192kHz
8-channel wav) after recording and before playback (the original
question was about recording long soundfiles; now you are talking
about playback; it's a bit hard to tell what you want to achieve)

as for the quality: if you don't want to do the maths, listen to it.
if it sounds good, then it's probably good.
it all depends very much on the sounds you are actually using. e.g.
8bit might sound horrible in general, but if you are doing C64-style
music anyhow, there might not be so much difference.
