The only place I would look to get free audio books would be on Amazon. If you try looking on Amazon you will find many different free books and Audio books to purchase.
You can find free audio books from the open culture website and also the podio books website. If you have an iPhone, iPod touch, or any smart phone you can download some audio books for free. Also the free section on iTunes had free audio books.
I personally feel that free online tools are not very stable, and I prefer to use audio editing software. You can find many free audio editors by searching online. Currently, I use the built-in free audio editor of TuneCable BeatOne. This software can both download music and edit audio. Speed up/down, fade in and fade out, adjust audio volume, cut/copy clips and other functions are free and unlimited to use.
You can find thousands of audio books many are free or at a low cost. Libraries are a really good source for free audio books, all you need is a library card. As far as audio content online, you should check out LibriVox. They have over 5,000 free audio books recorded by volunteer narrators.
