[Q]MPEG Audio decoder's quality....

Started by Park, Sam-Yook September 27, 2000
Hi.
What's the main factor to make different MPEG Audio decoder's quality?
(Especially, for MPEG-1 audio)
I had read about the benchmark of mpeg audio decoder's quality, bot I can't find it again now..
If it is done exactly same platform (32-bit CPU, sam OS), what's the main consideration?

Main consideration is numerical accuracy, particularly of block operations 
like IMDCT and DCT

Here are some benchmarks.
