alright, my mistake was that i didn't use integers as multiples of the binsize for reading out the buffers. now it's working fine.
a final question: having 2 buffers (for real & imag) sized 10000 milliseconds, i can have a maximum delay of 2496 ms. is that because of 4 overlapping windows? mirko -------- Original-Nachricht -------- Datum: Mon, 4 Jun 2007 22:59:08 +0300 Von: "ugur guney" <[EMAIL PROTECTED]> An: "Mirko Maier" <[EMAIL PROTECTED]> Betreff: Re: [PD] binweise delay > http://crca.ucsd.edu/~msp/techniques/latest/book-html/node179.html > # You can take a look at this page for help in FFT. > # How did you impelement the buffered analysis? > # I think something like this could work: If the number of bins is 2*N, > prepare N tables with size N samples. 1st table has one in 1st sample and > zero everywhere.
