Doug,
Easy to slow down the recordings (or speed up) with computer - or an
'antique' Uher 4-speed reel to reel. But halve the speed and the pitch
drops an octave. Can you slow the recording and retain the same pitch? Or
does changing the pitch also help you to a better understanding of the
sounds?
Fascinating anyway.
Cheers
Syd
