Hey all,
First off, I'm looking at
http://www.vttoth.com/digimix.htm
and thinking of implementing the algorithm he describes for mixing
multiple buffers. The algorithm requires knowledge of the range of sample
values for normalization....
Since we are using Float32's....what is their range? I think this would
mean its a single-preceision. IEEE 754 says single precision have a range
of about 2^127.
Anyone know?
Second:
What is the recommended way to remove a parameter from the user's view in
an AudioUnit? Right now I'm returning _InvalidParameter when I want it to
disappear, and it works.
