(I'll write any necessary conversion > utilities, but I need the algorithms first) I believe the SNES sound chip uses a FFT (Fast Fourier Transform) method for its compression scheme. The audio data is run through a FFT, to compute the frequency spectrum data. This data is what is stored in the cartridge. Without knowing the specifics of the FFT used by the SNES sound chip, you could be in for a rough time. -- Michael Portuesi Silicon Graphics, Inc. port...@sgi.com
