Update: Andre Michelle wrote some much better code to adjust the pitch of an external sound. I was secretly hoping he would. Check it out at http://blog.andre-michelle.com/2009/pitch-mp3. Thanks Andre!
Here is another sound example that shows how to adjust the pitch of an external sound. This is an extension of the example that can be found in the documentation for the Sound.extract method. Now this example does adjust the pitch but it also speeds the song up as well. This is because you need to skip some samples in order to increase the pitch. Now there are ways to increase the pitch of sounds without speeding them up but I have no idea how to do it. Do you?
Click on the image below to see the example. It uses my throw slider which you can toss back and forth. It may take a minute for the song to load so please be patient. You can download the FLA file if you want to see how it was done.
