This term designates the work of someone who is involved with an interdisciplinary artwork in which the intention is holistic, namely, that the impact of the work is greater than the sum of its constituent parts. In other words, a sound designer normally makes a sound organisation for a specific interdisciplinary work in close collaboration with those representing the other art form(s). The sound organisation is most likely not an autonomous composition.
