[vlc-devel] Why do we use fi32?

Is there any reason why we use 32-bits fixed point (fi32) for audio
filtering with !HAVE_FPU? I could not find any *non-trivial* audio filter
in the VLC tree that would implement fi32. Why don't we use s16l instead?
It would save conversion from fi32 to s16l toward the audio output, and in
many case converting from s16l to fi32 from the decoder.
