Hi Gabriel,

I think main problem of nspsytune's tonality estimation method is that frequency resolution of 1024 point FFT is not enough. But, simply using longer FFT degrades time resolution, and it may cause another problem. So, I'm implementing new tonality estimation algorithm which uses long FIR filter instead of FFT. Since I have not so much spare time currently, it's implementation is proceeding only little by little. Fatboy is not a tonality estimation problem. I believe it's fixed by more sophisticated psymodel of temporal masking. -- Naoki Shibata e-mail : [EMAIL PROTECTED] _______________________________________________ mp3encoder mailing list [EMAIL PROTECTED] http://minnie.tuhs.org/mailman/listinfo/mp3encoder
