It uses an algorithm to isolate background noise from quiet sections of your mix and then applies that profile to filter noise from the entire recording. The aim is to remove or reduce the noise as much as possible without altering the underlying signals. The process can be very effective at removing continuous or repetitive noise that degrades the final sound output.
Background noise is background or ambient sound in a recording. Any sound or interference that was unintended is background noise. There are many types of noise such as hum, hiss, buzz, whistles, rumble and crackle that can be generated by sources such as audio recording equipment, electronic interference or simply noise in the room.
Sensitivity sets the level of noise reduction. The higher the Sensitivity setting, the more noise is reduced however more artefacts or imperfections may occur in the output. As a guide, the signal-to-noise ratio can be increased by 5 to 20 dB without noticeable loss of audio quality.
No, it can't reduce occasional or irregular noises such as individual clicks and pops. It can also be difficult to get good results if the noise is very loud or the music or speech is not much louder than the noise itself.
