Reader Marc Edwards has shared two new videos, embedded here, and an in-depth article looking at the vocal effects of Daft Punk.

The videos cover Daft Punk’s use of vocoders and harmonizes to create vocal effects. The article digs into the details of which devices the group used, and how to recreate their effects.

“I believe my article is likely the only source online for some of the information,” notes Edwards. “It took a couple of years to research.”
