In any gathering these days you might find even more smartphones than people, all of them equipped with loudspeakers and connected to the net; just waiting to be controlled centrally, synchronized and joined together to form a socially aggregated, digitally integrated sound system. Using innovative technologies, we bundle these phones into a massive, intricate sound system with numerous distinct sound sources scattered throughout the space. All of which play back different, complementing parts of the whole sonic information, creating a truly multi-layered, immersive aural experience in super-surround. No additional hardware needed.

The workshop presents a hands-on introduction to SADISS, a web-based application developed in the research project The Choir & the Sound System at Anton Bruckner Private University. SADISS enables socially aggregated, digitally integrated sound systems to create two different forms of portable seas of sound:

  • a massive multi-channel sound system for re-synthesizing compositions right in the middle of the gathering of listeners using their smartphones’ loudspeakers.
  • facilitating ad hoc choirs of human singers, individually guided via headphones.

The sound system facilitates the creation of portable, crowd-sized seas of sound, opening wholly new fields for composers and artists to explore.
