Hi tomylee
I hear it!
I have built a different sigfile. Settings betweem 10100 and 10200, closer to the second value, cause aliasing noise. Adding freq modulation with an lfo makes things even clearer, since a periodic sweep across the above zone triggers the noise. I have kept Q at 1 thru tests. Audio is stereo and analog in, @ 48KHz sampling rate.
Raising the q eliminates alising "almost" completely. I can still hear some "-zzzz" though.
Will pass to DSP dept with accurate description.
Thanks for your report
Italo
