AW: [sdiy] some observations : audibility of phase distortion

[TIm Daugard]

My understanding from lots of physics books is that the speed of sound is the
same for all frequencies. It varies with material or air i.e. speed through
metal is faster than speed through air. It varies with air temp and pressure.

The explanation in a music and physics book points out that if the speed varied
with frequency, a symphony orchestra playing tightly in sync would sound lousy
100 feet away.
