Noise reduction parameters


I’m not sure what the “sensitivity” stands for in the noise reduction procedure. I know it sets a threshold to determine if a certain frequency component should be reduced, but what is the unit of sensitivity? Is it also in dB?

As far as I’m aware, it doesn’t have units. It’s just an arbitrary “lower <—> higher” scale.

It is similar to the “Threshold” setting of a Noise Gate. If set too low (below the noise floor), then the effect will do nothing. If set too high, then it will remove sounds that are a bit above the noise floor in addition to the noise.

Settings between 3 and 6 are usually best. For gentle noise reduction, try setting it to 3. Higher numbers will reduce the noise more, but will also remove more “not noise” sounds. Setting it to zero disables the effect.
