For Un-drum 3/Semantic Scanning Electron Microscope, Atoui has developed an audio library of tens of thousands of microsamples to explore semantics through a system analogous to a scanning electron microscope (SEM). Like a SEM, which magnifies things on a ?ne scale, the tools of Un-drum 3 allow live exploration of long audio tracks at a very small scale. Through a system of pressure sensors that engage the physical strength of the artist’s body, Atoui scans tracks at a high speed to instantly select and edit microsamples based on the Fast Fourier Transform analysis technique. FFT is a complex sound analysis protocol that determines the spectrum of a sound, its constituting frequencies, and their density according to the law of Fourier. Systems of infrared modules respond to Atoui’s movements to select microsamples according to mathematical serial algorithms that create elaborate rhythmical structures of hundreds of microsamples played simultaneously.
