Should you release an audiobook simultaneously with the ebook/hardcopy?

[Quantum]

I think the answer is yes. I'll do it when I release my first one. Yes, there is a higher initial cost, but I think that this is an investment that will increase your chances of selling more book across the board.

Out of this week's 7 released books highlighted by this Goodreads article, 6 of them have audiobooks.
