After you have published your book, the next step is Audio. ACX.com is the place to go. It isn’t the easiest site to navigate, but that’s the place to get your books recorded and place them in Audible’s vast library.
The procedure is simple once you navigate through the site.
The biggest problem is finding a voice to do your recording if you do not want do record it yourself. It is possible to record your own voice and use that for the final product and I would recommend that route if you have a good voice, can do different voices for your characters, and have 50 or so hours to do the job. Some special equipment is also recommended and may even be required depending on what you already have.
You can contract a voice for your book on ACX. There are two possible contracts. The first is you pay by the length of the book. This can range from a few hundred dollars to thousands depending on the frills and the reputation of the voice. The second way is to split the revenue from audio book sales. It’s a straight 50/50 split on the Audible sales. Unless you are a good selling author with a great volume of ebook and/or paperback sales there are not too many who will join you in the effort.
The nice thing is you approve every chapter before final print. You will audition the voice. Both of these are part of the process.
One word of caution here, if you use ACX and Audible you tie up your book for digital audio format for 7 years with Audible.
A voice I will recommend without reservation is Charles (Charlie) Baker at http://www.cbvoice7.blogspot.com. To contact him directly at email@example.com. He has done two of my books and I am extremely happy with the result.
