What about the idea of representing the threshold as an interactive horizontal
line? The attack, release and ratio could also be represented as a single bezier
curve with 3 control points. And the output waveform would be drawn over the
input waveform, for visual comparison. All of this over a short period as you

Also, I personally find waveforms useful when trying to achieve loudness, but
I'm not much of a sound engineer.

That's what I think. Also, visualization can be pedagogical, as here if the
musician is not very familiar with compression.
