The most basic Walsh-Hadamard Transform does precisely as much mixing as
a DCT/DST/FFT of similar length.
Sure - and we'd expect WHT coeffs of iid noise to be Gaussian right? My
intent with the scare quotes on mixing there was a hand-wave to the
various relaxed conditions wherein the CLT still

The expected value you describe is equal to the zero signal (this follows
immediately from symmetry), not a
Hi,
Just a reminder that if you are new to the list you should read the
music-dsp FAQ. It contains answers to both technical _and_
adminstrative questions that often come up on the list. If your question
appears in the FAQ it is safe to assume that it has been discussed on the
list many times in
