De-noise via spectral subtraction
An introduction to the technique is described in this blog article.
How to use the plugin
Load the plugin into your preferred Digital Audio Workstation (I use Ableton Live 9).
Adjust all the controls until the noise is removed but without causing audible artifacts. Note: the de-noising is applied independently to the left and right channels. See the screenshot below illustrating typical settings for the controls. Included is the display of the Ableton Live clip being cleaned.
