HarmonicBoost by ChromaDSP

Interesting little thing worth to check in-depht

[*] Polyphonic pitch tracking to boost the signal with harmonically matching content.
[*] Real-time synthesis of octave and interval shifts.
[*] Separate interval controls for left and right channel to enhance the stereo field.
[*] Smoothing control regulates the compromise of tracking speed and accuracy.
[*] Dropdown menu to compensate tracking latency and report it to the host.
[*] Visualizations to illustrate the boost signal.
[*] Supported sample rates: 44.1, 48, 88.2, 96 and 192 kHz.

Notes from the developer:
[*] Since I’m doing this by myself, I can’t test the plugin in all hosts and configurations. If you find bugs don’t hesitate to contact me.
[*] In general I’m happy about any kind of feedback, questions or suggestions

If the dev chimes in:
a) Used it in Live 11 beta for a while. No bugs so far. CPU is a somewhat high-ish but that's the plugin maybe? Will test more in other DAWs later.
b) How is this technically realized? Is this some kind of delay/resonators/comb filtering stuff?

Thanks for this post and the interest in my plugin! Good to hear that it works in your configuration. However, I already got some feedback from other peoples after releasing it and meanwhile did an update, where I tried to fix the major issues.

Technically the algorithm mainly uses two things:
- Chroma Feature Extraction
- Additive Synthesis
Basically the visualizations indicate whats happening inside - Chroma Features on the left and additional, octave based, weights for the Additive Synthesis on the right.

Cool to have the dev onboard.

When I first read about it, I came to think of Zynaptiq's AdaptiVerb, which is very clear, as it changes according to harmonies.

Perhaps you could do about the same thing with HarmonicBoost? Perhaps a collab with (I'm dreaming here) Valhalla?

Then you could end up with something like this beauty, but with your own sets of tweaks and quirks (check the vid for inspiration)!

This thing is actually pretty decent
