The bluetooth chip also allows us to stream uncompress un"dumbed"down stereo audio wirelessly at either 441.K 16bit or 51kbps mp3 depending upon the user's preference.

So you meant 44.1k/16bit wav or 512kbps mp3? okay THAT is clear then. The original wording you used was confusing

isnt 320kbps the max bitrate for mp3?

Also 44.1k/16bit and 320kbps (or 512 like you claim) are not mutually exclusive.. in fact they are completely different properties. 44.1k is the sample rate, 16bit is the bit depth and kbps is the bitrate

listing them separately is not a good indication of quality. You can have 44.1khz 16bit audio at 64kbps and it will sound horrible.. whereas 44.1khz/16bit encoded at 256kbps will sound much better.

If im given 2 recording options.. one that is 44.1k/16bit and the other being 512kbps.. i am going to be confused. Its safe to assume that 512kbps is good quality because it would be pointless to use that high of a bitrate with a low samplerate and bit depth. But the 44.1k/16bit option gives me no indication on its quality.. is it 32kbps.. 128.. 256?
