Then the following window will open:
Noise reduction
Select the "Get profile from selection" item, then save the profile to a separate file. Next, just close this window and select the entire file (ctrl + A), open our window again through the main menu: Effects-Noise reduction - Noise reduction
And load a previously saved profile. You need to adjust the level of noise removal. It is important that the recording does not leave the characteristic overtones of noise removal, which can be compared with the overtones of low bitrate recordings. Often such overtones are the result of an incorrect choice of noise profile. However, in most cases, this method allows you to get rid of the noise, which can be verified by looking at the spectrogram: view - spectral view.
At home, without the use of tools for cleaning recordings from noise, it is difficult to obtain high-quality sound recordings, since these noises will most likely become more noticeable in the future when the dynamic range is narrowed (compression).
It is also important to have the best possible quality headphones/speakers (monitors) to listen to the results of the recording. Without them, it is difficult to assess how well the sound was recorded. Of course, a professional sound card is just as important. To understand what it is about, you just need to listen to the sound on various sound cards, somewhere you can hear noise and the sound is muddy, somewhere the sound is simply amazing in its transparency. The same records sound completely different.

1.2.Premises and sound recording

Well, in the days of analogue, recording with hot signals really was the best way to achieve a high signal to noise ratio. That’s because signals would be recorded through multiple pieces of analogue equipment. Each of these had a greater noise floor than the kind we experience today in digital recording. So recording with hot signals was a necessary part of maintaining a high signal to noise ratio throughout the signal chain. This remained best practice in 16-bit digital recording too, due to its relatively limited dynamic range.
When it comes to modern day 24-bit digital recording however, things are very different. You don’t need to get the signal particularly hot to overcome the noise floor. As such, you can achieve an ample signal to noise ratio at a far more conservative level. So with 24-bit digital recording, the signal doesn’t need to be anywhere near clipping to achieve proper audio recording levels.
