I think this is the right choice for intermediate computations. Alexei gave some hints how to use 16.16 stuff. > The problem with 16.16 is that most of the bits in the integer part > will not be used because I am normalizing the values between [-1.0, > 1.0] before outputting the data.

The only remaining question is how to represent the final output data. 8bit? 16bit? Werner
