Noise removal workflow

[Jason Gerard DeRose]

Big thanks to Wind Up Toy (https://twitter.com/#!/wind_up_toy) for feedback on noise removal workflow!

Assuming I understood things correctly, key element are:

1) You select a portion of audio clip to be used as reference silence
2) There is a slider (or similar) that allows you to adjust how aggressively noise is removed
3) You play clip in a loop and listen in real time to results as you adjust the slider
4) Must have toggle to play back what is being removed rather than what's left (especially to hear when voices are starting to be removed)

Two things I thought of after conversation with Wind Up Toy:

For (1), it might be handy to automatically select the reference silence, which sometimes will be what the user wanted. As long as they can still select another region just as quickly as when there is a automatic selection, seems like a win. Need feedback on this.

For (3), it might be handy to be able to select a subset of a clip to loop over... so you can, say, hear effects of noise removal on a key piece of dialog, over and over in quick iteration.

This will take more research, but wanted to get this noted as a starting point.
