Hello all, I've been looking for some sample code on sounds for carbon OS X without any luck, any advise would be appreciated.

Thank you all.

I found the old Sound Manager functions easiest to deal with - you should be able to find something using them somewhere in the Source Code section (where I learned from), or you could download the source to MAFFia (my uDG entry), which I know has it. It's 3.8 MB, mostly graphics I'm afraid, but sound.c should have most of what you need.

Thanks w_reade I have some sounds working!!
I'm working on 3D game using Open GL, I wanted to have more control ever the sound, but for now your suggestion will do just fine.

Once I got something ready to show I'll post it here.

I wish Apple had an easier way to deal with sounds on 3D.

My pleasure, glad to help.

Oh yeah - If you're using OpenGL, how about OpenAL for the sound? I've never used it myself but I hear it has a similar interface to OpenGL, and may offer the control you're afterÖ it might be just what you're looking for.

I'll take a look at OpenAL

Jabber is it possible to take a look at code or a demo?

Thanks again..

Code:

#define    kFullLeft -kFullVolume

#define kFullRight kFullVolume

OSStatus PanSpeakers(SndChannelPtr theChannel, short panPos)

{

    short        theVolumeLeft, theVolumeRight;

    OSStatus    err;

    SndCommand    theCmd;

    theVolumeRight = kFullVolume + panPos;

    theVolumeLeft = kFullVolume - panPos;

    theCmd.param1 = 0;

    theCmd.param2 = (long)((long)theVolumeRight << 16L | theVolumeLeft);

    theCmd.cmd = volumeCmd;

    err = SndDoImmediate(theChannel, &theCmd);

    return err;

}

Should work with Mac OS 9 and X. panPos should be anywhere between -128 to 128. -128 being full left speaker, 0 begin center and 128 being full right speaker.

I really wanted to use OpenAL, but My project is carbon CFM and OpenAL is a framework.
I looked at the sample code CallMachOFramework from Apple, but it only works with frameworks in the System/Library/frameworks not on Library/frameworks.

Should I change all my code to work with Mach-0

Any suggestions?
