unpredictability equation in psychoacoustic model 2

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.

Best regards,
Alexander
