I've been experimenting with MP3 and converting my CDs to MP3-320 compressed files. Unfortunately, I've discovered that the MP3 encoding process destroys the Rear Channel Sound. In a few cases I can still hear music in the rear, but for most songs the rear speaker just produces garbage sound... rather disappointing compared to the rich sound produced from the original CD!

I suppose MP3 considers the rear channel information to be "inaudible" which it would be in a standard 2-speaker stereo arrangement, but the addition of the rear speaker makes these types of sounds *very* audible. It's basically an echo effect that is audible when listening to the CD and places the listener *inside* the music, but sadly lacking on the MP3 rip. The stripping of that rear channel echo dramatically diminishes the experience.

P.S. I'm using CDex for ripping and LAME for encoding with the following settings: q=0;Very High Quality, Stereo, 320kbps.

My DVD rips are all encoded with alt ABR 128 and the surround info is fine.


ew! ew! ew!

192ABR/CBR (stereo) is a BARE MINIMUM... holy crap! blink.gif even APS -M S (stereo) sounds a bit odd. 224 to 256 seems to be the sweet spot for the music i've been experimenting with recently (like 99% eurodance, electronica, etc) .. i need to try some hard rock, tho; i have the Guano Apes sitting right here begging to be re-ripped ever since i discovered how APS (in its defaulting to Joint Stereo) utterly destroys the soundfield.

for the rest of you tweakers, the most buttugly example i can find of stereo being jacked up is Crazytown's Darkside .. *shudders* ... sounds pretty cool when played as a WAV/APE or high, high quality MP3...
