Quoted from "Flatline"
afaik wirkt sich der codec nicht auf die Kompabilität (bin mir mehr als unsicher mit der Schreibweise grad ;D ) sondern nur auf die Qualität aus. Auf der Audiograbber (der übrigens auch gut ist) - homepage wird der lame-encoder propagiert.

;D

But the main purpose of joint stereo is not to save bits, but to account for some stereo unmasking problems that could arise.
Quoted
Yes, they are - unmasking effects appear when the sounds in some frequency areas of L and R channel have very similar masking threshold level (in dB)
L/R coding mode is used exactly when the oposite condition is met - when left and right channel differ too much - so, no unmasking problems in that case.
So, consider something like this to be a reasonable psychoacoustic thinking:
- Do L and R channels differ less than some threshold (say, 2 dB) ?
- If YES, then employ M/S coding for that band, and also employ "masking level depression" (MLD), by correcting of the thresholds
- If NO, then employ L/R coding for that band
The problem with MP3 is, that it do not allow switching per frequency band, only per frame - so you need to come out with some kind of averaging mechanism.
