Yes, but if you compress music to fit into a 64kbps stream you have to mangle it a lot. There is no way to have it be "CD quality" Which means you've dropped into the "how near is near enough" discussion. To my ears, not near enough, not enough bits. > Can't say I have a grasp of where in > the bps rating they consider something "CD" quality. Red Book CDs are roughly 150kBytes/second or roughly 1.5 Mbps With Flac (and probably MLP or other lossless compression) you can get about 2 to 1, so you can talk about a 750 kBytes/s stream having all the bits. Anything less gets into subjective areas. They use acoustic masking and other techniques to drop out sounds that are not important. Who decides, and what is important is not clear. I have tested several codecs that deliver pretty good sound at 500 Kbits/s or so. But I would not call it CD quality. Plenty good enough for a car or other place where you can't do critical listening. The marketing folks in the music industry have deliberately mixed "digital" and "quality" The Sirus and XM radio folks do the same. To me, Red Book CD without loss is the minimum for serious listening.
