Same volume across files

Actually, I messed up a step. The Audiobook Mastering worked out for my files. Thank you all for the tutorials.

I am attaching one audio clip with samples from two different files. Is there a way to adjust the first 5 seconds to sound more like the second 10 seconds? The client says the first 5 seconds sounds louder. I did the audiobook mastering steps to both files as outlined previously in this thread. Thank you.

The client is right, there is a difference. You really want to wait for one of our Audiobook elves to pitch in here. Until they do, here are some steps I took to make them sound the same.

1) Create a label at about 5.5 seconds so we can separate the tracks.
2) Select left-half of audio, then Amplify, but Cancel or Undo, but note the suggested amplification level is 4.64.
3) Select the right-half of audio, then faux Amplify. Note the suggested amplifcation here is 4.409, we'll used these numbers later in step 6.
4) Select left-half, Effect > Loudness Normalization; use defaults
5) Select right-half, Effect > Loudness Normalization; use defaults. (Be sure to do these separately)
6) Select all (Ctrl+A), Amplify, set New Peak Amplitude (dB) to 4.52 (=4.64+4.409/2)

I hope this helps.

BTW, it is not a good idea to re-edit MP3 files, but I think you already know this.
