Get access to eBooks. You'll find them in a wide variety of formats. If you want to transcribe one, secure all of the text. You can download eBooks from numerous sites. Some of the books are in the public domain and require no payment. Others must be bought.
Deal with copyright issues. Before you begin your project, get all the necessary clearances from publishers and authors. This may involve your paying a fee and royalties.
Get recording equipment. For an audiobook of any quality, a good microphone is essential. Online audiophile sites provide tips for what kind of home mic may be best for your project.
Set up your home studio. Obtain a software recording package or other means of handling your audio streams. Getting your hands on development tools you can work with is key. Without a comprehensive way to engineer your audiobook, your project could turn into a fiasco.
Set up a block of time for recording your audiobook. If you feel your voice is up to the task, you can be your own narrator. If you will be hiring an outside narrator, be sure the studio times are well scheduled to meet any contingencies that might arise.
Get the audiobook onto discs or into audio files for distribution through a site. Getting your product to the public means packaging it in a way that you can work with. If you're sending it out to a mass printer, make sure it's in top condition before you let it go. The distributor is the last step of the process and a last chance to correct any issues.
