First thing’s first—with any audio issue, you have to identify what it is in order to treat it. Is it distortion? Hum? Noise from a fan? Once you’ve identified the issue, the question becomes: what tools can you use to treat the audio and get the desired sound?
Successful audio repair in post, mixing, and mastering often depends on the correct sequence of processing steps. For example, impulse noise repair algorithms like RX’s Mouth De-click module, should be run first, ahead of any hum or broadband noise reduction.
As a general guideline, we suggest this flowchart of processing steps for audio repair. For many audio restoration problems, there are multiple modules in RX that can be used alternatively or in sequence.
