Let's call it an expander (or compander). From the description below it looks like Tim is trying to build an expander (which is essentially an inverted limiter).

From that average volume, I can then derive a gain value such that when the gain is applied, the signal is at or near zero. Then, I allow any samples with a volume greater than zero to be further processed.
