Is it possible to make sound waves (loudness) affect another parameter such as Multiply, Saturation, Glow, etc. of other strips? It's something like a visualized sound wave, yet the result I want is glow (on a picture) to increase when the sound gets louder, and glow to decrease when it's quieter.

EDIT: I accidentally stumbled upon a way to solve it! It's called "bake sound to f-curves".

EDIT #2: Is it possible to adjust the levels of the baked curves? I can go as far as a value of 1 when the sound is maxed out in Audacity. I can decrease the threshold by lowering the volume in Audacity as well, but there's no way to go beyond that. Maybe there's a way to do that in Blender itself? You see, not all the Blender effect values go only from 0 to 1. Sometimes it needs a negative value, sometimes - a dozen.

EDIT #3: Yeah, figured it out. It's done by adding a Noise modifier to an F-Curve, and selecting Multiply for the Blend Type.

First you have to add a key frame to a property. You can then proceed to use bake sound to f-curves.
