The FFT implementation is very rudimentary. Use more refined FFT or DHT to improve performance.

Also note that the precision of the current rudimentary FFT implementation does not seem to be as good as hoped (or maybe could be). Can the precision be improved --- even for the rudimentary FFT implementation?

A simple improvement resulting in reduced runtime would be to support FFTs having lengths of 2^k times 1 or 3, instead of just 2^k times 1.
