Simply buying the plugin won't fix your audio. You need a workflow. Here is the "X4 Chain" used by professional restorers:
Pro Tip: iKey Tools X4 allows you to process audio in reverse. If you have a degraded cassette tape (where the trailing edge of the sound is duller), reverse the audio clip, run DeNoise, then reverse it back. This evens out the tonal response.
The workhorse of the suite. Unlike simple broadband noise gates, DeNoise X4 uses a spectral dynamics algorithm.
