Scott, this is the first time I've ever heard of
the concept of phase-rotating to increase loudness.
It seems to me that if you use a filter that merely
performs frequency-dependent phase-shifting but
without changing amplitude, you may make the
waveform have greater (or lesser) maxima, but the
actual volume should stay the same.

Can you elaborate?

Thanks,
