I have a set of MP3 files which I want to amplify similarly.
What I thought to do was: import them all, amp all together, then re-export them. And I want the original time lengths of each file reproduced in the re-export.
So when I “Import Audio” and select them all to get them into Audacity, I get each file in its own track, all tracks starting at zero mark.
At this point, I’m thinking I need to be able to shift each track to the END of the previous one, then amp all, then have marks at all end-of-track points, then “export multiple” using the label marks.
But I would like to not have to shift each track manually, since there’s 100 odd file/tracks, and I can’t find any “align” tracks that does this.
Is it possible to make all the tracks each shift to each previous tracks end, and get marks at those point, or is there a better way to amp all & end up with a set of same time length files as I started with?

This is impossible due to the nature of MP3 encoders. But if you don’t mind a tiny bit of added silence then read on.
You’ll want to use Audacity 1.3.3 for this because of it’s superior Normalize function.
Import all the tracks. Don’t worry about Time Shifting them, it’s not at all necessary.
Highlight everything and use the Normalize Effect. Set it to normalize to whatever level you want. This might take awhile.
Now, as long as all the songs are in their own separate tracks, you can use Export Multiple to export each track to it’s own file. Set it to ‘Split Files Based on Tracks’. It will use each track’s name as the name of the file it’s exporting to, so make sure you export to a new folder to avoid over-writing any files.
