When recording, the quality of the microphone path is very important. Any unwanted noise during processing, mixing and mastering will surely "come out" in the mix and will be perfectly heard, which will reduce the quality of the phonogram and spoil the impression of listening to it.

Step 1
Indoor noise can also cause unwanted noise in the soundtrack. This is especially noticeable when using wide directivity condenser microphones or increasing the sensitivity of the microphone input. If in the first case you have to properly drown out the room, covering it with sound-absorbing surfaces, then in the second it will be enough to lower the sensitivity of the microphone input.
Step 2
If uniform noise during recording of a microphone signal is caused by equipment (computers, air conditioners) or poor soundproofing of the room (especially for home recording) and it is not possible to eliminate it before the next recording, you can use a noise gate, or a digital noise reduction algorithm.
Step 3
Noyce gate is a device that interrupts the signal if its level is lower than the specified one. Typically, the noise level is much lower than the desired signal level. All sounds that are noticeably quieter than the useful signal (the sound from a guitar or keyboard amplifier, drums and other powerful sources), as it were, are cut off when the gate is turned on. During the passage of a loud sound through the gate, the gate is turned off, but the noise is masked by the useful signal. The threshold level is adjusted manually. This way you can achieve no noise leakage into the recording.
Step 4
When recording quieter sound sources (vocals, acoustic guitar, violin, etc.), you can use one of the digital noise reduction algorithms. In the case of large professional studios, these algorithms are implemented using expensive digital devices, while in a home studio, you can use a regular computer and one or another plug-in for adaptive noise reduction or pattern noise reduction. Both algorithms have great possibilities for adjusting the noise reduction parameters and, as a rule, have an option that allows you to listen to both the signal after cleaning and the clipped noise. If a useful signal leaks into the noise removed from the phonogram, the settings can be changed.
