Noise gate

[vsariola]

It would be nice to have a thresholding / noise gate unit. https://en.wikipedia.org/wiki/Noise_gate

At simplest, a hard thresholding would be something like:

if (abs(signal) < threshold) {
  signal = 0
}

Features to be considered, if they cannot be implemented with the help of other units:

• Hysteresis
• Attack / Release i.e. transitions from gate on to gate off
• Hold: how long to keep the gate open after signal drops below threshold
• Ability to side-chain it: e.g. the input to noise gate is a signal before reverb; gate has hold, and then the gate is applied after the reverb. This prevents a very long tail from the reverb.

unless you did something there already, I would implement that in the near future (cause I also want one)

(what are you thoughts on "Hysteresis"?)
