So - I have some audio that I’m analysing and I need to do some things to in the spectral domain and then I’d like to move to a Mel bands representation at (or near) the end of the process for individual frames. My processing is not really designed for resynthesis so ideally I’d pass the FFT frame direct to the Mel transform, but there’s no way to do this right now.
Is there any relatively easy way (even tacky) to test this kind of process with the current objects? I’d certainly prefer to pass the audio a frame at a time (rather than going back into the time domain an overlapping) but I appreciate that might not be possible. One eventual option for me is to roll an object that does this (likely in FrameLib land), but it’d be good to avoid this for now until I know if it is going o improve my results.
you can compute the bands with the code I’ve put in the drum-vocoder example, but that is the only way to do the process on spectral frame. our objects do not support that at the moment. You could also pass on the audio data in the buf version and just take the right frame. For instance, if you pass 1024 samples with 1024 - 1024 frame-and-hop sizes you should get back one frame only and that should be cookin’
I’ve tried looking for drum/vocoder, but I suspect what you are referring to is either on the forum or named differently as a file. A link or path would be much appreciated. Thanks.
I think it’s this subpatcher from the fluid.melbands~
