Speaking of which, how would you record something underwater? Special
underwater mics? Mics tightly enclosed in bags? How much are these
underwater mics? I would like to have one :)

How about putting speakers in water proof bags and playing them
underwater....ok, I'm getting out of hand here..

Someone had requested that I post a report on how my 'underwater
ambience' project worked out.

After a surprisingly convoluted combination of processes (each of
which added something unique to the journey), I did manage to turn
ordinary gentle surf into something somewhat reminiscent of an
underwater environment in the presence of a scuba diver.

The ingredients:
- fairly severe bandpass
- pitch shift (a bit under an octave down)
- time expansion (to slow down wave action)
- very slow 'flanging' + light, slow doppler
- stereo image widening

After all that, one definitely would _not_ want to listen to this
material critically (!) but for BG ambience it is acceptable in

Thanks again for the suggestions - you all definitely steered me in
the right direction.
