Trond Lossius is a sound and installation artist living in Bergen, Norway, mainly working on audio-visual installations and other cross-disciplinary projects, often using multi-channel sound reproduction in his installations for sculptural exploration of the space as well as creating imagined spaces through sound. He will talk about the exploration of various spatialisation techniques in his work, and development related to spatialisation within the framework of Jamoma.

Jamoma is an open-source (GNU LGPL) software development platform for interactive research and artistic practice, co-developed by an international team of researchers, developers, artists, composers and musicians, providing a framework for structured development and control of modules in the graphical media environment Max/MSP/Jitter. Spatial sound is a core interest to several of the developers. A stratified approach to spatialisation and the development of Spatial Sound Description Interchange Format (SpatDIF) encourage interoperability and flexibility between modules, and Jamoma supports a number of advanced algoritms for spatialisation, including Vector-Based Amplitude Panning (VBAP), first and higher-order ambisonics, as well as novel spatialisation methods Virtual Microphone Control (ViMiC) and Distance-Based Amplitude Panning (DBAP).

Most common techniques for spatialization require the listener to be positioned at a “sweet spot” surrounded by loudspeakers. For real-world concert, stage, and installation applications such layouts may not be practical or desirable. DBAP offers an alternative panning-based spatialization method where no assumptions are made concerning the layout of the speaker array nor the position of the listener. The basic principles underlying DBAP will be presented, as well as extensions to the algorithm for added flexibility and artistic expressive possibilities.

Trond Lossius graduated with a master degree in geophysics from the University of Bergen, and went on to study music and composition at The Grieg Academy. He is currently art director at BEK – Bergen Centre for Electronic Arts, Associate Professor at Bergen National Academy of the Arts and a member of the Management committee of a COST action on Sonic Interaction Design (SID).
