In digital music composition, requests are often made to place and move sound sources. For multichannel loudspeaker reproduction systems, many current applications typically execute this process based on simple amplitude-panning laws. Apart from positioning sound sources around the listener, this approach can't create other spatial attributes, such as source width, distance, and room impression. ViMiC provides a computer-generated virtual environment for this purpose.
ViMiC (Virtual Microphone Control) is a new spatial sound rendering tool in real-time, particularly for concert situations and site-specific immersive installations. Drawn from psycho-acoustical research and the principles of audio recording techniques, ViMiC generates loudspeaker signals which differ in terms of amplitude and time-delays. Furthermore, the generation of time-accurate early reflections increases the auditory illusion of spatialization. Through its flexible configuration, ViMiC particularly supports non uniform loudspeaker arrangements.It will be demonstrated how ViMiC can be used to spatially enrich sound scenes.
Nils Peters is a PhD Candidate in Music Technology at McGill University and affiliated with the Centre for Interdisciplinary Research in Music Media and Technology (CIRMMT). His research focuses on the Perception and Modeling of spatialized sounds. He studied electrical and audio engineering at the University for Music and Dramatic Arts and the University of Technology (Graz, Austria) and graduated with distinction. He has been working as an audio engineer in the fields of recording, postproduction and live electronics in Germany, Austria, France and Canada.
