Creating an Audio book

I posted a dB explainer.

As DVDdoug above, home readers have trouble passing noise. It’s hard to get used to the idea that your room noises and electronic noise have to both be 1000 times quieter than your voice. That’s what the -60dB ACX noise limit means.

I have a nice quiet room to record in, but I still have to hide the ticking wall clock in another room and wait for the Metrobus to go by.

If you miss noise by a little, you can use noise reduction tools to put you over the edge. If you miss it by a lot, the tools can create sound damage. ACX Quality Control is looking for processing damage and may fail you if they find any.
