Audio books have been discussed a bit before, but I never saw a list of recommendations. What books are good in an audio format (especially ones that can be listened to while driving)? I commute 45 minutes a day and would like to put that time to good use.
ETA: I'm mostly interested in non-fiction (goal here is to learn useful stuff, as opposed to entertainment).
If you're doing courses, you may want to speed up the playback and shift down the pitch.
If you're doing anything else, you may also want to speed up the playback and shift down the pitch. To achieve that you may use a tool like Audacity (open source, many platforms, Effect > Change Tempo…) or SoundStretch. I use this to automate podcast shifting on my mac.
