"Loom" was created using a new technique of composition called Musical Tapestries, with which the sound sculptor is able to selectively separate real world sound scenes into re-usable component templates and re-compose these templates (with potentially massive time, frequency, and other transformations) into a sonic tapestry. The template extraction, transformation, and re-synthesis are enabled by a new program, application, and software development framework that integrates sinusoidal modeling, wavelet-tree decomposition, and transient extraction / manipulation with a novel interactive interface, providing a complete workbench for separating, manipulating, and re-composing natural and other sounds.
"Loom" was re-composed using only a handful of different templates extracted from recordings of natural sounds. They include 1) a bird squawk, 2) bird chirp, 3) duck quack, 4) lutine bell, 5) children yelling (9 instances). We re-compose these in the tradition of Musique Concrete, but with tools previously unavailable. For example, a bird cadenza shows the massive time-scale differences one can achieve by morphing a flock of birds (created from a single chirp template) over a wide range. Also, the children's drone in the second movement is achieved using 100x time-stretching and 50x frequency-warping. Granular synthesis, stochastic modeling, and other techniques are also exploited in our system and in the composition "Loom."
