Free Audio Books
LibriVox is the king of free audio books. You can use the catalog to search through their library of nearly 1000 works, all part of the public domain. If you’re feeling generous, you can even contribute wiki-style by recording audio of your own.
AudioBooksForFree also has a big catalog to sort through, with an emphasis on classic works, but a decent amount of mystery, sci-fi, and thriller as well. The only catch here is that you’ll have to pay for quality: the lowest quality downloads are free but anything better than 8 Kbps costs $5-8.
If you’re looking for classics, FreeClassicAudioBooks is a nice resource. Although the library isn’t huge, the selection includes quality authors and titles and downloading convenience in an iPod-ready format.
Who knew that on top of all that print content, ProjectGutenberg also has a huge audio section? They’ve got everything from Aesop to Zola, including a decent number of works in French, German, and other languages.
LearnOutLoud has over 500 educational titles and offers a lot of video as well.
The bright side here is that you can probably get almost any older work in the public domain for free. If what you’re looking for is a bit more modern you’ll either have to shell out a few dollars or try to find a relevant podcast.
