Convolution and FFT are the only things I can think of that work with parallel GPU processing and neither are really big CPU hogging things anyway.
There’s such a difference in realtime audio needs to video or scientific computing and that’s why GPU’s aren’t being used in audio, it just isn’t suitable.
for example IIR filers;
IIR filters are the basis of envelope filter which are the basis for virtually all dynamic effects that go beyond basic wave shaping. So what should we do about those effects
IIR filters can not be parallelized.
there’s one real world example of just one type of processing.
