Hi all,
Can anybody tell me the Theory and derivation behind the
unpredictability equation in psychoacoustic model 2 used in mp3 audio encoder ?
Thanks in advance.

Hi, you might want to check out this thread in music-dsp. The equation itself gives the normalized prediction error per frequency bin.
