The updated algorithm has two main improvements:
- The silence padding is not constant but a ratio of the original
silence (up to a defined max) to more naturally represent the
original gaps.
- The silence is not instantly going to zero, but uses a ramp down
and up for a smooth volume transition and also retains a small
percentage of the original noise for more natural "silences" that
still contain some background noise.
