Does anyone know of something similar for automatic analysis of audio using the FFT? There are visual ways to do it, but it would be nice to have an automated s

  Late reply but you can actually do this with the library as is. It's not designed for it so you'll have to use fftw yourself and call some borderline internal stuff, but it ought to work the same. float* samples = ... //load audio samples here int len = ... fftwf_plan p = fftwf_plan_r2r_1d(len,samples,samples,FFTW_REDFT10,FFTW_ESTIMATE); fftwf_execute(p); RDResolution* res; size_t count; RDMethod* m = resdet_methods(); m->func(samples,len,1,1,&res,&count,12,m->threshold);
