Hi all

i'm trying to make an auto bpm finder for musepack.
To reach this goal I need to know if the encoder use a Windows switching pattern as mp3.

otherwise I've to find another method to recognize the beat.

mpc does not use window switching. it uses the same filterbank as mp1/mp2. you may detect transients via rapidly changing scalefactors -- e.g. watch the scalefactor of the lowest subband over time.
