So it's a gate?

Well, it would be more accurate to call it a spectral gate. A regular gate cuts out everything below a set threshold.

Technically, this takes the Fourier transform of the input signal which splits it up into 1,024 frequency bins. Those frequency bins that are smaller than the threshold are zeroed out and the result is then resynthesized using the inverse Fourier transform.

So, only the frequencies that are below the threshold are removed, instead of everything.

Also, with a regular gate, when the signal is above the threshold everything gets passed through, including the noise. With this, the noise is removed even when you are playing your synth.

Thanks for the device and your reply.

I understand, a spectral gate. Like a Denoiser which takes a (selected) area as noiseprint and then removes that from the signal.

Is it possible to reduce the tjirping left in the signal? Maybe with a higher amount of bins?

Hi Zeep, You can definitely change the number of frequency bins. Currently, there are 1024 of them, but you can change it to any power of 2. The next highest would be 2048.

got a funky bug - maybe its my setup, but when i switch to another window other than Ableton, the noise comes back.

I've never had that happen. But, I've noticed a lot of strange little quirks since live 10.1.0. For example, all of my dials used to be ultra smooth so that you could exactly dial into .001-.03 land and get even smoother by using the shift key. Doesn't work anymore, at least it doesn't on 10.1.6
