Click Suppression

To show the effect of changing Mono-a-Mono’s “Click Remover” slider, here are a couple of examples. You can click on the graphs to download the corresponding audio files.

This is a short extract from a stereo recording of “Never Took a Lesson in My Life” by Nat Gonella (the upper panel is the left channel, the lower is the right). As you can see, it’s very scratchy.

Zero click detection
Most of the remaining problems are due to the relatively few, but often large, clicks which occur simultaneously on both left and right channels. These can be almost completely removed by setting the “Click Remover” slider to full scale (10):
