But it's a huge simplification to say that 96 kbps "is equal to FM radio." FM radio has drawbacks and artifacts, and so does a 96 kbps mp3 or AAC stream. Maybe they're roughly the same level of degradation to most people's ears, but each has a very different sort of degradation. Some people object more to the odd added "details" and phasing/intermodulation anomalies of compressed digital than to the increased hiss and (pre-emphasis related) reduction in high-end levels of FM. And some feel the opposite. And Dave is right. A compressed-data signal that sounds quite acceptable in the car, or on speakers in a noisy home, can sound _much_ worse on headphones or in a pristine, silent listening environment, where its subtle details can be heard. At 260 or 320 kbps, I'm very happy with stereo mp3s, even on headphones. At 128 kbps, headphones and my best speakers reveal some occasionally annoying flaws. With every good wish, Kevin Alfred Strom. -- http://kevinalfredstrom.com/
