Presentation by Nils Peters, doctoral student at McGill.
In auditory virtual environments, often it is required to position an anechoic point source in three-dimensional space. When sources in such applications are to be displayed using multichannel loudspeaker reproduction systems, the processing is typically based upon simple amplitude-panning laws. Although this approach allows natural sounding spatial images, an accurate sound reproduction is limited to certain loudspeaker arrangements and listening area. This presentation describes an alternative approach based on an array of virtual microphones: In a virtual environment, virtual sound sources and microphones can be spatially placed and moved as desired. Depending on the displacement of the virtual microphones and their chosen directivity pattern, the captured audio signals contain amplitude and time differences to each other. These signals are used to project the virtual sound-scene through arbitrary loudspeaker arrangements.
Bio:
Nils Peters is a doctoral student at McGill University, Montreal, Canada, affiliated with the Centre for Interdisciplinary Research in Music Media and Technology (CIRMMT). Under supervision of Stephen McAdams and Jonas Braasch, he is studying spatial perception and spatialization techniques particularly for application in concert halls and for big audiences. Nils Peters has an MSc in Electrical and Sound Engineering from the Institute of Electronic Music and Acoustics (IEM) at the University for Technology Graz, Austria.
Presentasjonen skjer i tilknytning til en workshop om spatialisering som BEK arrangerer.
