Has anyone tried doing this? I was thing a 256-band FFT followed by 256 sinewave generators could provide the basis, but I am not sure how to detect and handle transients.

i dont think you can build an mpeg encoder in gen at all.

however, you can find transients by checking for the deltas between the amplitude values, and depending on the task you might want to /2 or squareroot these amplitude values before.

Does that work? Transients are defined as frequency transients (noise) and I dont know how that corresponds with amplitude. I would think it would be something to do with anplitude distribution after the fft but I dont know.

Its not an mpeg decoder, its just using the same psychoacoustic theory.

Hi , I found a spectral noise gate here which suggests how to add this part:
