I've taken my love for audiobooks to another level by helping to narrate Eminent Doctors: Their Lives and their Work; Vol. 1 on LibriVox.
Listen to chapters 1 and 2 if you're interested in the history of medicine in the UK.
There's also a high probability of curing insomnia if it ails you. 😉
I decided to use the straightforward Hindenburg Narrator since I was very familiar with the interface from using Hindenburg Pro for podcasting quite extensively. I also liked the integration of the ePub to make it easier (a.k.a. automatic) to add markers for chapters and paragraphs. It also includes handy presets for exporting the audiobook in a format compatible with ACX that I was able to easily adapt to the slightly different LibriVox requirements.
If you're interested in the behind-the-scenes, here is a minute or so of me recording chapter 2.
