My Audiobook Process for Removing A/C Fan Noise

[Zash]

@kozikowski

they are all perfectly clear and have velvety quiet background “noise.”

What does ACX apply to achieve that velvety quiet background?

I have a related question about audiobook distribution.

‘ACX distributes your audiobook to Audible.com, Amazon.com, and iTunes, the three leading retailers of audiobooks, as well as their global retail partners.’
Audiobooks Through ACX

I have also read this thread:

Audiobook distribution

This really does have something to do with creating files, I just didn’t know what to name the topic. A lot of folks here talk about ACX, and I remember a while back I was helped with producing a book and getting stuff together. I have a distributor for my own stuff that’s NOT ACX and I was looking at the specs for it today as I uploaded. I realized hey, there may be folks here who can use this information. They’re called Author’s Republic - and I’ve always gotten more from them than Amazon. …

I assume that ACX does not give us back their processed files, with the rights to submit them to competitive audiobook sites. Do all of these other sites (Google Audiobooks, Kobo Audiobooks, Downpour, etc) apply processing similar to ACX? Or will some of them simply publish the file as-submitted, assuming it passes their requirements, and if so should processing (e.g. noise floor) have been applied before submitting to them?
