Paper Note creates a tangible waveform from laser cut disks of paper. The user records a message, a sound or loads up music, and the system analyses the sound to map each moment to a corresponding slice. The circles are laid on a sheet, lasercut and put together to form a unified shape, representing the original sound wave.
The team programmed it using Processing. Each Paper Note is made up of around 450 stacked disks of paper. The louder the volume at a specific moment, the bigger the disk. Their algorithm samples the right amount of information from the recording to scale the physical waveform to the size of around 14cm.
