Hello,

I am using the "AS Pitch Detect Demo" and "AS Simple Pitch Detect Demo" as templates for a pitch detect script on which I'm working.

I have noticed in each of the running scripts, there is a "pitch detection flicker" that occurs, where the program seems to be measuring a pitch, even when there is no sound entering the input. I've put a gate on a digital sound input to make sure that no volume was entering the input, and the "pitch flicker" still occurs.

Is there some scripting I can use to remove the "pitch detection flicker" when no sound is entering the machine?

Any help would be appreciated.

Tim R.

Hi
normally the pitch detection algorithms in both apps do not detect a pitch unless there is sound coming in, i.e. the incoming volume is above a certain threshold.
There is probably a problem in your configuration which makes sound come in, or maybe a buzz internal to the sound card ? Try the Windows standard recording app (in accessories) to check what is heard by the computer. Or on a Mac, check the sound input preference to see the incoming level.
