Footprints of Creatures

Ulf A. S. Holbrook, Université de Montréal

An impulse is a signal which is entirely zero apart from a short spike of an arbitrary shape. Footprints of creatures is a journey into a terrain consisting of multitudes of small impulses, bent and shaped through networks of delays and filters. Although the sound materials are of an abstract origin, they are heard as through a sense of characterizations of space and object. The movement, shifts and turns in the sounds forms and disbands new relationships between sounds and their spaces and creates narratives before breaking up into abstraction.

Footprints of creatures is composed in 5th order higher order ambisonics and is presented in stereo.


Ulf A. S. Holbrook is a composer, sound artist and doctoral research fellow at the RITMO Center for Interdisciplinary Study on Rhythm, Time and Motion, Department of Musicology at the University of Oslo. The focus of his research is on the perception of sound objects in spatial audio representation systems at the convergence of signal processing applications and sonic creation. His research proposes the soundfield as a link between a sound object and the spatialisation of sound masses which share the same multidimensional space. His work is performed and exhibited in galleries, as well as at festivals and conferences internationally.
