This is a perfect example of when you would use a noise gate.
You have captured a perfect take of the vocalist, but in that recording you have also captured what engineers call click track bleed and muffled noises from next door. In this situation, you have got an almost great recording. As the vocalist goes through the motions, creating that perfect take, the microphone picks up the click track, as well as muffled noises from next door. When making recordings, noise from your environment and external sources accumulate and can affect the quality of your recording. Noise gates come in the form of software or hardware. Simply put, when used correctly a gate will block all unwanted noise. A noise gate or gate is a type of audio processor that is used to control excess noise in an audio signal.
