<< I love your description of Dolby Digital a five channels of MP3 >>Unfortunately, this is *not* a joke or an exaggeration. From the official DVD FAQ, by Jim Taylor, author of "DVD Demystified":
"Dolby Digital is multi-channel digital audio, using lossy AC-3 coding technology from PCM source with a sample rate of 48 kHz at up to 24 bits. The bitrate is 64 kbps to 448 kbps, with 384 or 448 being the normal rate for 5.1 channels and 192 being the typical rate for stereo"
If you do the math, you will see that the audio data rate is exactly in the same range as MP3 files -- between 128 and 192 kbps for stereo music.
It kind of makes you wonder why a market even exists for expensive surround-sound processors. Would you be willing to pay (say)$5000 for a multi-channel MP3 player?
