My cheap and easy solution is that I use a table lookup function on the
audio output. It looks like a compressor in that it is a 1to1 mapping up
to a certain point and then it curves, tending towards a gradient of zero.
This will scale down any samples that are not TOO huge but will,
obviously, distort them. The distortion is a LOT more pleasant than
digital clipping and I quite like it. I've started using it in all my
csound stuff as it means I never have to worry about clipping. I can
scale the volumes and remove it later if I want a perfectly clean signal.

Dunno about that :)

The other way is to generate your file in floats (on the platforms which
support it) and scale it all at the end.

I know several DJ's who have been using Csound for a while. So you're not
alone.

At the request of a couple of csound subscribers I've attempted to give an
example of how I implement the volume limiting I described in my earlier
mail. I originally intended to use a function for the curve, but in the
end I used a table into which I placed a few values from this curve and
I'm afraid I've completely lost the original function. It's not complex..
it was the result of about 5 minutes fiddling with gnuplot :) The curve in
my example isn't really very curved at all, but you can imagine that if
you added a few extra points you could achieve a much better
approximation. The important thing is that it works, quite well :)

ps. I use 16bit WAVs..my constants reflect that.

Has anyone got this to work? I'm using Gabriel Maldonado's version of
csound with a Turtle Beach MultiSound Pinnacle. I've tried -iadc,
-idevaudio, and -i"TBS Pro Series Wave In 1" (the name of my wave input
device).
Csound does not complain about -iadc and -idevaudio, but I
don't get any sound coming in. The real-time Wave output works just
fine.
My system is a P200MMX running the 'a' revision of Win95. I am using
the beta 4 pinnacle drivers, and have experienced no other recording
problems.
Thanks for any help,
Lorien Dunn
