I'm sure there are more ways that Goldwave noted at http://www.chuckegg.com/how-can-i-convert-audiblecom-aa-files-to-mp3-audio-files/
Can someone recommend software that will convert Audible audiobooks I have purchased to an MP3 format so that I can save on a flash drive? The Audible Manager allows me to burn to CD's but most books require so many CD's that its not worth the hassle.
