Recently Paul Clements posted a breakdown of a headphones project he put together. It's an awesome breakdown and hints at a few interesting techniques.
Since he posted it I've had a few questions about to go about replicating some of the effects in it, so this video answers a common one.
If you watch his video: vimeo.com/35145361 from about 10 seconds in you will see the effect we are going to look at.
