It seems like the noise frequency is directly related to the value of HZ and HZ=1000 is especially annoying as the ear is very sensitive. I was wondering how hard it would be to allow values of HZ in the range of 10-20 kHz? I have attempted to do so, but it seems like part of the code is not ready for that. Even after setting the right SHIFT_HZ in timex.h, setting HZ=10000 causes things like division by zero and negative shifts. Is there a way to do it anyway? Jean-Marc
