"Noise" is part of an audio signal that is not the intended signal. When you listen to music on the radio, you can hear the music, and usually also some noise. When computers record or play audio, the electronic components sometimes create extra noise. Sometimes it can be your background noise recorded your audio.

In order to remove ‘noise,’ we must first tell Audacity what the ‘noise’ sounds. Do this by selecting a portion of the audio where nobody is talking and noise has recorded – like a break in the conversation, so you just get the ‘noise’.

Generally fade in at the beginning of an audio segment, and fade out at the end of an audio segment. You can use Audacity to create special effects if you fade in or fade out in the middle of an audio segment. You can make a surprising effect by setting Audacity to fade in or out over a few second, then adding the opposite fade inside the first fade.
