[Flac] flac vs. mp3 decoder

[Harry Sack]

hi

I was wondering if Josh could tell me what the difference between the
cpu load (in %) of a flac vs. mp3 encoder is on the same cpu or an
estimation of it . I want to have an idea of this because I'm
wondering if playing flac files would use more cpu (in %) then playing
mp3 files on my pocket pc.
So if I would know this, I would know which decoder will empty my
battery the most quickly.

thx in advance
