Followup to Rok Papez's tests
I first downloaded Vorbis about a month ago, around the time Rok Papez posted
comparisons of Ogg and Lame [*]. Here's my much rougher test on a single file.
CPU: AMD K6-233
MP3: LAME 3.70, mp3blaster 2.0b6
Ogg: Vorbize 0.6 (Xiphophorus libVorbis I 20000718), ogg123-0.1
Data set: Ministry, "The Fall" (51,955,724 byte WAV)

Video codec
Hi,
I guess this is a good time to start putting together a wish list for a
video codec.
I see that for audio the compression is around 10X for reasonable quality.
I am sure this will start its own thread of conversation.
For video you can do 40X fairly easily and the big task is to go to 80X or
100X with reasonable picture quality, say, a peak luma SNR of more than 30
dB. Uncompressed
