1.2.6 noise removal superior to 1.3.6 ??

1. Select a noise profile.
2. Set the amount of distortion you’re willing to accept in the final show.
3. Go.

The software tries all the possible combinations of all the tools and variables and selects the best parameters that achieve the desired work…while I’m making a cuppa.

Sounds like a new feature for the PAF

In reality, Noise Removal is a trade-off of several factors. For example:
How much noise to remove?
How much frequency damage?
How much impulse response damage?
Do you just want to remove noise from the quiet parts and allow louder audio to “mask” the noise?
How much “bubbly” artefacts?
How much “swooshing”?
…

The “best” trade-off depends on the type of music, the type of noise and on personal taste/preference. Unfortunately there is no magic formula. There are however parameters that will usually be in the right ball-park for “average” music and “average” noise, which of course should be the default settings.

The main reason that the old 1.2.6 Noise Removal effect worked better on some audio samples than the 1.3.6 version was that the effect attacked noise within the music far more aggressively. The advantage of the 1.3.6 effect is that it caused far less damage to the louder (above the noise threshold) audio. The point of a “sensitivity” control is that it allows the user to decide where they make this particular trade-off. In most cases I think this should be to aim for least damage (as per the 1.3.6 version), but in some less common cases (the examples where the 1.2.6 effect produced a subjectively better result), the sensitivity threshold can be pushed up.
