# Close!
Altitude is not really that much of a factor in audio. But I was looking for the standard that is 343mps at 20c.

Classically used to set your delays.

The height of a 100Hz sinwave?:P

# Yes it does
But not that many gigs have been done on Everest you know.

Possibly something I saw in a magazine or when I was lecturing live sound at university:P

# Not right now,
but one day we'll all be playing gigs at flying parties, and we'll have to fiddle the delays on the video screens to match.

3 feet high, and rising...

# Well a one hertz cycle on 343mps would be 343m high
So 100 would be 34.3 metres:P
So therefore 1kHz 3.43m
etc
