AUDIO REPAIR

AND ENHANCEMENT

USING SPECTRAL REPAIR IN RX 4

In this chapter, we’ll explore using the RX 4 Spectral Repair module to remove intermittent noises and

ﬁll in unwanted gaps. We’ll begin with these algorithms as they work in particularly unique ways. Please

note that other audio repair and restoration solutions may not include the following functionality, or might

achieve the intended results dierently.

The process of using Spectral Repair requires making precise selections using either the basic or advanced

tools. If you’re using Spectral Repair as a plug-in inside a DAW, note that it includes a built in spectral editor

window that works in a similar way to RX 4’s interface.

TIP • We strongly recommend that you try the Spectral Repair examples included in the Appendix, as

well as the audio demo ﬁles that accompany this guide.
