Pitch Chop - analyzing and separating pitches in audio files


Recommended Posts

I am trying to use a pitch chop to split a given audio file into a series of channels where the value of the chop channel is the pitch, this would create a kind of square wave frequency pattern that could be used to drive a wave form in SOPs for example, so if the pitch is 440 the value of the chop channel would be 440 and could directly pipe into a SOP channel. 

It seems like pitch chop is the thing to use but its not quite working how I would want.  

The attached picture I photo shopped to show how ideally the chop channels would split out. 

The attached Hip shows my working example and audio test file.
