Apple

So to handle both cases, I would have to be able to render the samples as floats and sint16's?

I guess that is not that big a deal, but for the sake of argument, if I wanted to be able to use the same code for both, do you how I would make CA_PREFER_FIXED_POINT == 1 for the mac?

Thanks,

Bob

Oops! Forgot to reply-all back to the list there, sorry.

Personally, I wouldn't change CA_PREFER_FIXED_POINT. In our products we just handle both cases.

Thanks -- do you know anything about CA_PREFER_FIXED_POINT?

It seems that on OSX it wants the samples to be floats, where my iOS code uses SInt16's. Is there a way to tell OSX to use the Sint16's?

I can't just #define CA_PREFER_FIXED_POINT 1 can I?

You can #ifdef out the AudioSession stuff for your Mac OS X target, it's neither needed nor supported on OS X.

Your AUGraph code should port no problem, and as long as the mixer units you used were either kAudioUnitSubType_MultiChannelMixer or kAudioUnitSubType_MatrixMixer, you should be good to go. (kAudioUnitSubType_AU3DMixerEmbedded isn't supported on OS X)

Hello,

I am trying to develop a cross-platform app between iOS and Mac OS X. I am working on the audio portion.

On iOS I am using synthesized sound with an AVAudioSession, an AUGraph and some mixer units. It has been awhile since I looked at it so I am a little foggy on how it all goes together. But basically I am rendering samples into a buffer and playing them using these audio units.

What is the easiest simplest way to set up the same thing on Mac? Is the same code supported? I looked around in the sample code on the developer website, but I didn't see anything very close. I am going to take a look at that AVRecorder code, because I think that is what I used on iOS. But I wanted to ask here in case someone has a better idea.

Thanks
Bob
