You don't know libsamplerate, do you? libsamplerate provides multiple
resampling implementations. While all are fp, one does probably more
or less in fp what esd does in integer. (I haven't looked at the
resampling code of esound, I must admit, but it probably isn't much
worse than libsamplerate's SRC_ZERO_ORDER_HOLD.)

See http://www.mega-nerd.com/SRC/api_misc.html#Converters for more
info.
