musocity is showing you the 16KHz brickwall ceiling of compressed digital audio.

wma or mp3 would be the same as far as that brickwall at 16 goes.

For some reason, that software shows it to be at 13KHz. That may be because the particular RealTrack chosen was done at a lower kbps rate to save space as some of them are. Even so, 16KHz is the absolute maximum achievable with digital compression as we have it right now (160kbps should be about where you'd see the "full" 16 with an mp3, I believe wma uses different nemerical figures.)

But still, very few ears are going to hear the loss.
