Repair dialogue

In the Essential Sound panel, select Repair.

Select the checkbox for the property you want to reduce, and then use the slider to adjust the level between 0 and 10:

• Reduce Noise: Unwanted background noise, such as studio floor sounds, microphone noise, and clicks, is often captured in recordings. The proper amount of noise reduction depends on the type of background noise and the acceptable loss in quality for the remaining signal.
• Reduce Rumble: Rumble noise has a very low frequency that ranges below 80-Hz. It can be produced by a turntable motor or an action camera.
• DeHum: Noises with a single frequency in the 50-Hz range (common in Europe, Asia, and Africa) or the 60-Hz range (common in North and South America), like electrical interference due to power cables laid too close to the audio cables, cause a hum.
• DeEss: Noises with harsh, high-frequency S sounds, like sibilance in vocal recordings created by breathing or air movement between the microphone and the singer’s mouth, case ess sounds.
• Reduce Reverb: Reverb occurs when sound waves reflect off surfaces in an environment and blend with the original sound. You can reduce the reverb to make the audio sound like it's all coming from the same source.

Review the audio after applying the settings, and make additional tweaks to achieve the desired clarity.
