[Mplayer-users] dirty ideas to speedup libMP3

[Christoph Lampert]

Hi,

I found that on slow CPUs (and I mean slooooooow like mine), MP3 Audio
eats a lot of CPU time (up to 50%, it can't skip & often no MMX and/or 3dnow) I 
am looking for a way to speed this up. 

Would it be possible to 
1) preprocess audio data (uncompressed) to get a lower bitrate? like half or so?
2) process audio bitstream only partially, e.g. drop the highest frequencies,
s.th. quality gets lower, but decoding faster?
