Aaahh...nice catch.....it was actually 16,667 bytes per second. Using 1024 to divide makes it 16.28 KBps.
What can I take from this info relating to quality of the files being streamed? I guess it would depend on which compression format they use....
The sound is definitely better listening online vs. using the satelite radio.
Well with XM satellite radio I can hear a ton of compression artifacts even in my dad's Bose car stereo, I shudder to think of what it'd sound like with a nice pair of headphones or a nice speaker monitor setup...Bose setups tend to gloss over detail like that, so being able to hear it so clearly would mean it's pretty bad.
I haven't listened to any XM online radio streams though...but 64kbps is right at the edge of what is even remotely acceptable, doubling that to 128kbps actually would make a huge difference.
But keep in mind they're using AAC-HE, not just normal AAC so it will sound better than any other format encoded at 128Kbps.
