I seem to have almost everything working with my CoreAudio
implementation except for some small audio tweaks. My main problem
right now is with the distribution of Volume between 0..1 when using
the StereoMixerAU. I have implemented similar controls on windows
using DirectX, and was able to develop my own dB logarthmic conversion
so that when someone slides the Volume between 0..1 it is smooth. But
now I find that the distribution of volume on the Mac is a little
steep. Going between 1 and .5 is a large change while .5 to 0 gets
quiet very quickly. I'd like to come up with a way to have a nice
smooth (percentage based) audio distribution.
Is there an easy way to do this? Are there other ways to change the
volume on my graph (a bunch of AUConverters going into the
StereoMixer)? Is it possible to change the volume by dB rather than
0..1?
Thanks
