experimental fft freqshift

i found freqshift~ in extended but it does some strange aliasing and did even produced extreme amplitudes... which i currently cant reproduce
so i did a first experiment myself
it is samplerate dependant and has other little bugs but i think its somehow better than freqshift~

any suggestions ideas or whatever?

Re: experimental fft freqshift

Have you looked at H09.ssb.modulation? It does it without FFT and isn't sample rate dependent.

Re: experimental fft freqshift

thanks seems great
only downfall i could find is that it reflects at 0hz
well and that i refuse to understand what's happening ;)
