What is Core Audio Format?

It's Mac's main audio format and audio technology (*.caf). It's a container for AAC, IMA4, ect.

What is the advantage of this apple only format.
Is it not better to add a crossplattform format, like most other formats?

Well, since it's built into Apple's OS and technology, I would assume better or the use of less resources to play. I know it is on the iPhone and iTouch. If you load a Ogg file and play it, it will start off using around 160MB of memory. Then if you're making game, you could imagine how many audio files you have loaded and playing at the same time. Now maybe that's mostly the plugin take up most of that memory to play the files but I'm always looking for better use of resources and so forth.

The request is more for app and game development for Mac. Not so much for music on multiple platforms or devices. I mean if you knew something was going to optimize your app or game and wasn't cross platform, wouldn't you use it? I prefer things I develop to be as optimized as I can get it.

For Cocoa there's NSSound.
You won't have something like SoundFrequency or SoundPan but playing, stopping and changing volume are supported.

Haven't read about NSSound yet but will look into it.

Wilberts new lib pretty much covers this feature request.

PortAudio is cross platform and is well developed for PureBasic.

PortAudio is great for realtime rendering of audio samples but how does it help you with loading a .caf or .aac file ?

TBH, wouldn't you want something that's cross-platform, and non-memory-hogging, such as possibly MP3's (I've been told that they are very compressed, and they seem to use very little of my computer's resources)? I'm new to this language in specific, but not computers. In fact, just googled a survey tonight, and about 39% of people have Macs. Wouldn't you want a larger market (Market being figuratively. IDK if you plan to sell any of this or not) than 40% of the computing world?

39% of people have Macs

That sounds like a very unlikely figure.

I thought it was like 2% which had Mac

You can play ACC or M4a in Windows and Linux using FFPlay from FFMPEG.
Or even better, using Bass dll which is a real advanced sound system.
