[Solved] Equalize Volume of MP3 Concert Recording: Audacity Tutorial for Leveling Audio Levels

I have a concert recording in mp3 format. Like a concert concert - sometimes it's louder, sometimes it's quieter. I would like to equalize the volume of the entire recording to one level. How to do it? Can it be done by Audacity? If so, in what way?

Well, this is what a good recording is about, to have great dynamics.

Not really, because some parts of the vocal are hard to hear at all.

As for the volume correction of record fragments, you can manually adjust the envelope tool. On the other hand, if the volume of the recording is relatively even and the vocal itself disappears, unfortunately there is no simple possibility of correcting such one "instrument" in the ready mix. The vocal path itself should have been isolated beforehand. In some recordings with a better or worse effect, it is possible to achieve this by removing the differences in the channels and leaving the common part, but we are talking here rather about studio recordings where the vocal clearly stands out against the background of the panorama of instruments (this is how the karaoke / vocal effects work. remover).

Thank you for your help.
