>From what I remember, the limiter sets the audio waveform clipping at the
top of the spectrum when you use the lowest limiter setting. As you increase
the limiter value, the clipping level gets lower and lower, approaching the
quieter voice/music waveforms. The best use is to lower the clipping level,
by increasing the limiter value, to clip (lop off) the offending spikes
before you increase the value enough that speech or music audio becomes
clipped too. Spikes can be lightning, auto ignition noise, etc. I've used it
with success in the past.
