I wonder if there are any VSTs which remove automatically the main harmonic content from an audio source.

For example, if I have a simple sine wave this hypothetical device would return absolutely nothing, silence.

If the sine wave has been previously distorted a bit, then this device would return at least some of the noise produced by the distortion, omitting the frequency of the original sine wave.

What I wish is a tool that does not only automatically remove one single frequency, but a set of frequencies that might be harmonically related. For example, passing a pure sawtooth trough the device would also return silence.

I think that a device like this has to exist already. Any pointers?

Thanks! :)

Maybe better for software recommendations SE? –  Dom Apr 30 at 17:00
    
hmm, it's a very specific question. I may risk not getting any answer there. They don't even have proper tags for this question –  francesco stablum Apr 30 at 17:02
    
I think the DSP site is the one for this question. –  Bob Broadley Apr 30 at 17:07

@BobBroadley : thanks, didn't know it existed :) –  francesco stablum Apr 30 at 17:08

@BobBroadley I think it is on topic here too. Timbre and amplitude dynamics are essential to both practice and performance. –  JCPedroza Apr 30 at 17:33

Izotope RX has a tool called de-construct, which is basically a mixer between the tonal and noisy parts of a sound, tonal being the partials that are related.

To achieve what you want you set the tonal gain fader to -inf (the lowest).

It is not a real time tool, though.

Thanks! This will surely be useful :) –  francesco stablum Apr 30 at 17:14
