mad and audioconvert are very cpu intensive elements.

You would need to develop/use a mp3 decoder that use the dsp in the
omap3, or develop/use a mp3 decoder that make use of the neon
instructions instead of the generic ones, and finally get  rid of the
audioconvert, delivering the raw audio as is consumed by alsa.

Either case you'd need to develop it, or buy it, because i'm not aware
of open source version of those elements.
