[mad-dev] Quantizing mad_fixed_t?

[Arve Knudsen]

I see that the algorithm for 32 bit output in madplay quantizes to 24 bit; I'm 
a little daft when it comes to fixed point representations, but why are some 
of the fractional bits discarded even when you're outputting in full 32 
bit? 

There's also one more thing I don't understand; the original sign bit of the 
fixed point number isn't kept (as far as I can see), instead the least 
significant whole part bit occupies the sign position. Does this whole part 
bit represent the sign (a little confused here)?
