The Monthly Challenge: Audio Hacks

I know that a week is a short time to do a great project and I wanted to start giving people more time to get their projects together, so I have decided to turn the weekly challenge into a monthly challenge. What this means for you is that you will now have more time, more chances to win, and better prizes. I am looking forward to seeing everyone's awesome entries.

The winners are now in. With so many awesome entries, it was hard narrowing it down. That said... narrow it down I did. Here are the winners. Thanks again to all who entered!
