For his diploma project (work in progress) at the University of art & Design Lausanne, Valerio Spoletini decided to combine two of his personal interests: scratching and vjing.

VScratch allows a visual transcription of every elements used for scratch composition. It transposes all sound nuances made by the rotation of the record: the variations of speed, audio spectrum and volume.
In addition of the volume and frequences of sound, the physical act of spinning the record back and forth is transmitted by an optical mouse set on the paper, in the middle of the record. All these variables are processed with java language, edited in Processing, and animate a grid.

The movies are quite impressive. Valero Spoletino will perform at Sonar on June 15.

UPDATE: thanks to the readers who suggested me a similar work: Jesse Kriss‘ Visual Scratch is a realtime visualization of scratch DJ performance, built using Processing, Max/MSP, Ms. Pinky, and MaxLink.

More night club stuff: Remote Vjs control, Sewing machine VJ, PostVinyl, Tremor tactile music sleeve, Interview of UnitedVisualArtists.
Thanks Angelo!
