In digital music composition, it is often desired 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. The Virtual Microphone Control (ViMiC) system provides a computer-generated virtual environment for this purpose.
ViMiC is a real-time rendering system, particularly for concert situations and site-specific immersive installations. Drawn from psycho-acoustical research and the principles of audio recording techniques, ViMiC generates loudspeaker feeds 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 post-doctoral researcher at the International Computer Science Institute (ICSI) and the Center for New Music and Audio Technologies (CNAMT). He holds an MSc degree in Electrical and Audio Engineering from the University for Music and Dramatic Arts and the University of Technology in Graz, Austria which was awarded with distinction.
Recently he defended his PhD thesis at McGill University, Montreal in Music Technology which is entitled "Sweet [re]production: Developing sound spatialization tools for musical applications with emphasis on sweet spot and off-center perception".
