Hello,
I wanted to know if someone here knows how evenly level volume in a track.
My issue is that I had to audio inputs with different volumes switching every 60sec.
I am attaching an example.

Many thanks in advance.

Envelope Tool is one solution …
As the music is repetitive, you could use repair channel plugin to patch-in a section at the transitions, if you’re having trouble hiding the join with envelope tool …

My problem is that this is a 4 hour recording with volume changing every 1 minute.

Why is that? What happened?
Its not a software issue, its the recording itself.
every 60sec the broadcasting software was switching between 2 video scenes with audio source that had different volumes in each scenes.

Robert J H wrote Nyquist code which chops alternately between channels .
Theoretically***** that code could split the track into loud on one channel & quiet on the other.
Then raise the volume on quiet channel to match the loud one (+10dB)…
[ ***** In practice it may not work if the timings are not exact ].

This may make the job a bit quicker, provided that the switching remains exactly every 60 seconds
“Regular interval labels” http://manual.audacityteam.org/man/regular_interval_labels.html
Create labels every 60 seconds
Time Shift tool to drag the track so that the changes in level coincide as closely as possible with the labels.
“Command + A” to select all, then “Edit > Labeled Audio > Split” (http://manual.audacityteam.org/man/edit_menu_labeled_audio.html#split )
Double click on the first quiet section, and apply the “Amplify” effect, set to amplify by 10 dB.
Double click on the next quiet section and “Command + R” to repeat the Amplify effect.
Repeat steps 5 for each of the quiet sections.

steve:
Double click on the next quiet section and “Command + R” to repeat the Amplify effect.
Repeat steps 5 for each of the quiet sections.
i.e. repeat step #5 , (which involves 4 key/button presses), one-hundred-and-twenty times .
