Reduce Noise: Reduce the level of unwanted noises in the background, like the sound of an
air-conditioning unit, rustling clothes, or system noise.
Reduce Rumble: Reduce low-frequency sound, such as engine noise or some wind noise.
DeHum: Reduce electrical interference hum. In North and South America, this is in the
60Hz range, while in Europe, Asia, and Africa, it’s in the 50Hz range. If your microphone
cable was lying next to a power cable, you may have this intrusive but easy-to-remove
unwanted sound.
DeEss: Reduce harsh, high-frequency “ess”-like sounds common in the sibilance part of
voice recordings.
Reduce Reverb: When recording in an environment with a lot of reflective surfaces, some
of the sound may be reflected back to the microphone as reverb. This can be reduced to
make vocals clearer.Different clips are likely to benefit from one or more of these cleanup features, and often you
will use a combination.
The default settings have high enough intensity to make it clear when a repair is enabled. In most
cases, you will obtain the best results by starting with a setting of 0 and increasing the intensity
until you are happy with the result, minimizing potential distortion.
Let’s try cleaning up some power hum.
