In any gathering these days you might find even more smartphones than people, all of which 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.

SADISS is a web-based application developed in the research project ‘The Choir & the Sound System’ at the Institute for Composition, Conducting and Computer Music of the Anton Bruckner University (Linz, Austria) that bundles smartphones into monumental yet intricate sound systems, also providing means for guiding ad-hoc ensembles.

Using innovative technologies, we bundle 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.

SADISS enables socially aggregated, digitally integrated sound and performance systems in two different ways:

  • a massively multi-channel sound system for re-synthesizing compositions right in the middle of the gathering of listeners using their smartphones’ loudspeakers.
  • facilitating ad hoc ensembles of human singers or performers, individually guided (potentially synchronously in different languages ) via headphones

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

Learn more about SADISS through our documentation and also get to the core of SADISS through our GitHub repository.
