MP3 encoding certainly uses Fourier, the question is how important it is...

I've tried building lame 3.83 with libmoto, and it seems to make no real
difference :(

I've just replaced -lm in the Makefiles by -lmoto, and I've noticed that the
binary is still dynamically linked against libm - is there anything else I
have to do for libmoto to be used?
