It seems that that person on RB knows more about the EDIG player than EDIG has ever put in print.

"ITS SIMPLE MATH... i have a mp3 player with about a 100 songs on my pc now at 80 bps, the compression rato to my understanding with the micro/os system is 10 times that of an mp3 player.."

Is this right?

The Lucent release says "Music is compressed at a rate of 11 to 1... which provides CD-transparent sound at 128 kbps."
Mp3 compression is quoted as 12:1 - less than 10% difference in compression, not 10 times !?

Also note:
Lucent says:
"Lucent's PAC was recently rated the best performing audio coding technology in a class of five tested in independent trials by Moulton Laboratories. In this test, PAC at 96 kbps outperformed the MPEG-2 Advanced Audio Coder (AAC). At 96 kbps, PAC also outperformed AAC at 128 kbps based on a repeatable statistical score"

ATT says:

"MPEG-AAC is more current technology than MP-3 (MPEG-1 Layer 3), and an independent study published in The Journal of the Audio Engineering Society, March 1998 has confirmed that the AAC platform provides superior audio performance to MP-3."

So PAC outperforms AAC (even with AAC at higher sample rates) which outperforms MP3.

(Then there's MPEG4 with VQF (at 18:1) and AAC. How does this compare with EPAC?)

Will audio quality determine the standard? Or is it just going to be whoever carves out the largest market share first?
