Re: [Faudiostream-users] Fftw foreign function
A common linking issue with fftw is that you are using (and not linking) à specific precision for fftw (fftwf or fftwl).

Ok, Thanks so much, I'll try to ask there.

Re: [Faudiostream-users] Fftw foreign function
This seems more a link issue, not really related to Faust by itself right ? In any case we can possibly chat and try to help on Faust Discord: https://faust.grame.fr/community/help/#faust-on-discord Stéphane > Le 18 févr. 2024 à 09:58, Francesco Vitucci a écrit : > > Good morning, > I'm trying to use fftw to write a foreign function that can perform some > tasks based on the Fourier transform.
