FFmpeg supports both fixed point and floating point 
mp3 decoding.

I tested a long time ago and FFmpeg was not slower 
on most hardware (but not always), libmpg123 has 
seen speed improvements since.

If the performance is of any relevance for you, 
please test yourself.
(I remember using a very long sample to get 
useful results.)
