Apart from summing at input ports and optionally dithering
the output signals Jack doesn't do any audio calculations.
The summing is of course what we are discussing. It would
probably depend on how Jack's summing code works - if the
inner loop is over buffers then the intermediate sums are
probably full precision. If it is over samples then the
intermediate results are probably stored as floats.
