@juliavithoria Bah, si tenés repo git podrías compartirlo por ahí también... y agregar códigos para tener ejemplos... hace siglos que no veo #Fourier, algo de la transformada discreta había estudiado, pero nunca programé nada con #FFTW.
Current memory limitation is between 4 and 8 million points due to memory exhaustion on my 8GB card. The implementation is about 12x as fast as #fftw in _measure_ mode on the Ryzen 5900x

ok, we're closing our #mobilizon instance registration. spammers just won't give up trying selling us youtube clicks. we don't care about yt since we're enthusiastic users of #peertube of which we also host an instance. #fftw #fediverse #selfhosting

bye bye @youtubeviewsindia

@melissasage If you are a programmer then key libraries are #sndfile and #fftw, for sound file IO and discrete Fourier transforms which are useful for spectral processing.

To do realtime audio, I prefer using #Jack, but also #sdl #sdl2 has merits as it works with #pulseaudio so casual users are more likely to run it successfully, and it is supported by #emscripten which can compile to web apps that run in the browser. Ideally add both back-ends to your code, and maybe also #oss for #bsd.

@IceWolf I've been using a simple program called "Impulse" with #PulseAudio for my own music-reactive lighting. It's written in C and invokes the #FFTW library ( http://www.fftw.org/ ), then has a Python library that consumes it.

I threw out the Python part and wrote C bindings in the language I'm using for my project (plus fixed some memory leaks/deadlocks).
