Hi All,

I'm working with Aure who is working on a version of CsoundObj on OSX.
The problem is that the audio output is extremely loud and distorted.
The code is based mainly on the iOS CsoundObj.  It is available at:

https://github.com/aure/csound/tree/updates-for-osx-ios

You can use these two commands to get his dev branch:

git clone https://github.com/aure/csound.git
git checkout updates-for-osx-ios


I looked into this a little but and so far I've determined that
AudioUnitSampleType on iOS defaults to SInt32, while on OSX it is
defaulting to Float32.  I think this is causing problems when the
AudioUnit is setup.

If anyone has a chance to assist here, it'd be very much appreciated!

Thanks!
steven

That should be simple to fix. The Float32 sample will be normalised between +1 and -1, as in
the InOut/rtauhal.c code.

Thanks Victor,

Taking a look at rtauhal.c sorted it out.  I just had to take out the
coefficient code from both the ins and outs and that got it working.

Thanks!
