320 is quite a considerable reduction in quality, even more if it is also
done in Joint Stereo, which also reduces stereo separation as well. It can
barely be called CD quality.
128 is so diabolically compressed that much of the detail of the track is
lost, rather like listening to a cassette tape. Nothing resembling CD
quality.
BUT, it all depends on how you listen to it, if you use a sound card and
computer speakers, you will not even be in a position to judge the
difference.
To extract the sound from the computer you need a digital to analogue
converter or better still a device that gives you an optical output that you
can plug directly into a decent quality audio system.
To convert 320 files to 128, you need to convert back to a WAV file and then
reconvert to 128, both processes lose quality and detail, imagine buying a
CD, recording it to a cassette, then doing an analogue copy of that cassette
before listening to it, that is basically what you will be doing.
It is of course entirely up to you, but if you do this, please make sure
that the resulting adulterated files are NOT shared, and do not end up
polluting the Internet.
