[vorbis] Vorbis on Legacy hardware

[Corey Miller]

I thought the CPU requirement for Ogg and MP3 were about the same, 
especially with tremor.  Can someone give me more information on these 
"low accuracy mods" on the tremor engine I keep hearing about?  Can the 
amount of accuracy vary?  I was hoping to write something that could 
play oggs on even REALLY horrible hardware.  My idea was to have the 
accuracy change dynamically through playback based on an equation like 
A=1-(R-(T)) where A is the accuracy (1 being full accuracy), R is the 
time required to decode T milliseconds of audio and T being an 
arbitrary number that could be tweaked until the best system was found. 
  Of course that equation isn't exactly what I would use but you get the 
idea.  That way even the univac could decode the music, lol, it would 
just sound horrible.
