Yesterday I just tested the 'dam' opcode to compress the output of
all my instruments (the instruments add to a global audio variable which
is then read out by the 'mixer' instrument which then outputs with
'outs'). You are right, it sounds like I would be 'listening to it on my
favorite college station...'. So 'dam' produces extreme noise, it a total
catastrophe. I will implement a compressor directly in csound, using
'rms' opcode to measure the sound level etc.
I hope this will sound better...
