I’d like to see a control added to the Noise Removal effect. This effect does a fantastic job for most purposes and is a huge improvement over 1.2.6, but I’ve encountered a situation in which violating the instructions a bit yields a worthwhile improvement.
The situation was:
The only significant noise to be removed was tape hiss. Applying Noise Removal based on a sample of pure tape hiss dulled the heck out of a low-amplitude chime instrument our drummer uses. I don’t know what it’s called, but it looks like a rack of small wind chimes. Same problem with a gentle cymbal (brushed or tapped) sound with no other instrument playing. I experimented (a lot) and found that if I duplicated the noise sample and fiddled with the amplitude of the new noise-sample track before using it as the noise sample I could nearly eliminate the damage to these subtle sounds without compromising the noise reduction.
What would have simplified this process is a “noise floor margin” control that adjusts how far above the noise floor a sound has to be to qualify as signal. This is essentially what I was doing by adjusting the noise sample amplitude.
