### Harmonic Creation

Posted:

**Mon Apr 18, 2016 8:49 am**Hi all,

I'm playing around with building a harmonic creator with 3 controls for the output:

1. Amount of fundamental (original tone)

2. Amount of ODD harmonics

3. Amount of EVEN harmonics

Though it is easy to create EVEN harmonics without the fundamental (and remove DC which is zero harmonic), I can't seem to figure out a way to create the odd harmonics without the fundamental. With any ODD harmonic creator I had found, the fundamental is part of the output, so I can't control it separately.

Is there a mathematical way to produce only ODD harmonics without the fundamental?

I've tried to subtract the input from output for that channel, but even that doesn't help. Something like:

If not by a mathematical function which can create ODD without fundamental, are there any smart ways to 'scoop' out the fundamental and give it its own 'intensity knob' one which differs from the 'ODD' harmonics intensity knob?

?

- Code: Select all
`output = ODD_Function(input) - input`
