The site is to be found at www.u-tune.nl and allows people to karaoke sing. The achievement here is that the vocals are then transformed using Autotune and after being merged with the music are played back to the user. As far as I know this is the first instance of Autotune being used on the web, it is intended to be a studio tool with a human configuring it. We really took the AUTO part of it seriously. :)
The project was one of the most challenging but also one of the most fun projects I have done lately.
