It sure does, but I can't reproduce it on my P4 based system which is normally very picky about denormals - CPU load is around 2.5% all the time. Also checked all parts of the code that could produce denormals: the HP processing filters, the k-meter and c-meter DSP code, and the volume controls. All have denormal protection. * Is the CPU load you mention the one measured by Jack, or some other ? * Try to find out which controls affect the CPU load. E.g. what happens when you have a signal but the volume is set to off etc. Ciao, -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities.
