post production noise gate

Help! I am not terribly smart about Garage Band so be patient. I narrated a long book (24 hours (yeah I know I'm nuts)), audio files using Mac 11.1 Big Sur and GarageBand 10.4.2. Pre-production noise gate was set at -85dB. I converted the audio files to MP3 and submitted for publication. The audiobook failed, too much background noise, with the suggestion from ACX Audiobooks that I set noise gate to -64dB. I need to do this post-production as I have no desire to re-narrate the book. Do I just go into each chapter audio file and slide the noise gate to -64dB and then reconvert to MP3 file and submit...or am I missing something? I'm a writer and a story-teller (and a surgeon); I know nothing about sound production. Thanks in advance.

Greetings,

As you may have already discovered the noise gate and other effects (echo, reverb, etc.) may be changed after the track is recorded. All that should be necessary is to change the dB setting on the recorded track. You may, or may not detect a difference depending on the value of the setting, but it can be "fiddled" with until it sounds good. Hope this helps.
