• Can you hear an improvement? If not, change the selection. The
selection should be as small as possible. Localize the audio
disturbance by trial and error.
• Once you are satisfied with the result, click on "Calculate". Up until
now, you merely experimented, but now the settings will be applied.
Tips: For information on the individual buttons in the editor, please
read the entire documentation (available as PDF manual or program
Help file). By the way, you can also access a tutorial video that
explains the workflow directly from within the Spectral Cleaning
Editor.
The Spectral Cleaning Editor might seem a bit complicated, but it is a
very effective tool that previously was reserved for pros. Therefore,
it's worth investing some time to familiarize yourself with this tool.
For Spectral Cleaning to work, the audio disturbance has to differ
clearly from the background. If this isn't the case or only partially
applies, you can try the DeNoiser.
DeNoiser
What to do, if the single cough turns into a coughing fit that drowns
out the actor's voice partially or entirely? You can't eliminate it using
Spectral Cleaning without also deleting parts of the speaker's voice.
In these more complicated cases, it can be useful to use the
DeNoiser. It's actually designed to remove consistent noise such as
hissing, but can also be used to filter out certain distortions.
Whereas Spectral Cleaning entirely replaces the distortion with
surrounding sounds, the DeNoiser filters out a specific sound
signature, a so-called "Noise sample", from the frequencies and does
not affect the rest of the material. This way, it can filter out a specific
distortion without affecting the background.
The DeNoiser can be accessed via the expert button located in the
"Auto noise reduction" module.
