HI all,

I'm looking at the Channel Conversion Header; in particular the "Target 
Channel (M) x Src Channel (N) Gain array". Why are these numbers some
sort of 15.16 fixed point value and not a 32 bit float?

Is that because we want to make it easy to implement this on CPUs without
floating point units?
