Guess it would be unpractical with all that inline assy.
The ideal would be as an earlier poster asked for: make a stand-alone library for the FFT.

It will not because the second argument to fat_seek_file was 0 and not a pointer to an offset as it needs to be. 2) fat16_example.pde says read(buffer) will read...
