ah sorry, yes i want to read a wavetable, say 128 steps and calculate the gain structure to aproximate this wavetable with sine waves. the idea behind this is to get a different sound from wavetables, use low resolution wavetables to get nice sounds (waldorf microwave xt)
so for a saw wave i would want the following numbers. 1 0.5 0.3333 0.25 0.2 and so on… how to do this for an arbitrary input wavetable? i looked at the fft examples but it is not clear to me how i would do this with a single wavetable (of known size) or if there is a “simpler” (without fft) possibility that would be great. > On 04 Aug 2016, at 10:05, José Rafael Subía Valdez <[email protected]> > wrote: > > Can you elaborate a bit what you want to do?? > > I think you better process the table rather than go from one domain to > another. > > inverse the phase by multiplying by -1, > you can "reverse" the table by reading it from back to front. > > > > On Thu, Aug 4, 2016 at 8:53 AM, Simon Iten <[email protected] > <mailto:[email protected]>> wrote: > sorry to post again. > > i think sigmund~ can do this. > > but i would be thankful for a hint how to calculate it. if it’s fft, then > some insight how to use fft on a single wavetable would be very nice. > > > On 04 Aug 2016, at 09:34, Simon Iten <[email protected] > > <mailto:[email protected]>> wrote: > > > > dear list, > > > > i can create nice wavetables with sinesum. > > > > what would be the easiest process to do the inverse? > > > > reading a wavetable of known size and converting it to it’s sine harmonics > > gain structure. > > > > fft? i am a little bit lost on how to do this with a wavetable. > > > > or is there a simpler way if i know the number of points and the range of > > the waveform? > > > > cheers > > > _______________________________________________ > [email protected] <mailto:[email protected]> mailing list > UNSUBSCRIBE and account-management -> > https://lists.puredata.info/listinfo/pd-list > <https://lists.puredata.info/listinfo/pd-list> > > > > -- > José Rafael Subía Valdez > www.jrsv.net <http://www.jrsv.net/> > > > >
