So how does that work? The easiest way is to use a service like Amazon's ACX service, the production arm of Audible.com. Here you have the option of being a producer or a rights holder (publisher). Narrators will either work for a flat rate based upon the finished time, not the production time, or elect to royalty share.
I just completed the narration for bestselling author, JC Ryan's The Tenth Cycle, an excellent series of 8 books, and I am now recording the next in the series, The Ninth Cycle: Antarctica. The process is straight forward. You need a professional quality microphone, a relatively sound-muted room, and a decent audio editor. Background sounds, hisses, pops, and breathing sounds, to name a few, must be removed. The finished product is uploaded chapter by chapter, and after Rights Holder approval, must pass the ACX audio team before being released.
I am also recording the audiobook narration for Robin Melhuish's novel, All That Remains, now available from Alt Publish no available in print no digital editions Online.
Audiobooks are a solid tool for enhancing your sales, no one you should not overlook. You can check out my narration of The Tenth Cycle at http://bit.ly/WGAudio. Let me know what you think in the comments.
