Optimizing my 128 channel IOProc.

Thanks to those folks who made suggestions on how to speed things up in my heavy laden 128 audio channel IOProc.

I delved into shark, and within 20 minutes I had shaved huge amounts off the tight loops.

Now, I have done what I think is practical in my own code, and I am left with something unusual.

In Shark, alongside my main IOProc for the input and my render proc for the output, I see 'AUMultibandCompressorEntry' taking a whopping 10%.

I have a feeling this must be related to the AUGraph Matrix Mixer I have on the back end of my application, but I am not using any compressors to my knowledge.

Can anyone shed any light ?

Cheers

Mark Gilbert.
