Visualization can allow realtime feedback of the applied effect as well as
improved interaction.

About my previous compressor example: imagine a single area where you have both
the input and the output waveform. It allows you to see the applied compression
but not only. The threshold above which the compression is applied can be
represented as an horizontal line which could be moved up and down.

Another example is a visual EQ as the one found in Jamin, where you both see the
live spectrum and can adjust frequency bands level.
