DSP guy here. I've managed to match Surge's FFT and numpy's FFT. They are not equivalent as it stands. Here are the differences: 1. Surge's FFT actually calculates the power...

Element-wise multiplication

> would you say our current implementation is wrong and should be fixed, or is it simply a different way of using FFT and we might want to provide a...

Hi @brett-eugenelabs, it's element-wise multiplication: same function as `vDSP_vmul` in Accelerate framework or `Surge.elmul` in Surge. Hope that helps 👍

Hi @abokhalel2, my example is just for the FFT on a single window, not an STFT. To get the STFT you would sliding window the samples and send it to...

@entibo thanks, you just saved me a lot of time.

👍 this library needs (more) documentation

@vade I unfortunately don't have time / brain bandwidth to jump into this in more detail but see above, this point specifically, which may help you understand: > Surge's FFT...

@vade I see you're contributing to an OpenAI whisper CoreML project. I like that. Find my email online and I'll share my Accelerate vDSP Mel Spectrogram code written in swift...

@annoybot see above, it has been answered
