So it might look like this: > > frequency(-band) harmonic > 25...50...75 0 > 50...100..150 1 > 100..200..300 2 i might be wrong here, but probably dave will help me out here.
if you construct an fft with the buffer size of 1024 and and a sample rate of 44100 hz, then the spectrum will contain values for frequencies below 22010 hz. the 22010 hz will be assigned to 1024 frequency bands equally, similarly to your table above. but these frequency bands will be post processed to get the values that are called harmonics in fluxus. and the mapping here is non-linear. there are no overlapping frequencies. the first 256 bands are used, some are contributing to harmonic 0, some to harmonic 1, etc. best, gabor
