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. -- FA _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
