Hi Dennis et al; Not sure if your comment was directed to me or not. I was simply responding to the stereo comment.
To clarify this, OpenAL does simulate 3D positional audio using two speakers. It certainly can also take advantage of more speakers if more are available to it but it does a great job with only two as well. For those who may not know, OpenAL is the default 3D audio library for iOS devices and the Mac so many of the games on iOS which use positional audio take advantage of at least some part of OpenAL. However, to the comments that sampling rate has nothing to do with the quality of audio, perhaps I am misunderstanding y’all here, but it most certainly does. :) Now, I am not saying that higher sample rates are better, but I am saying that they do matter when it comes to audio converters and such so yes, they can definitely affect the quality of audio. As you say though, they do not have anything to do with 3D sound positioning.. Have a great night! Cheers!

Lack of surround sound is probably pretty big though.
