The Hall-O-Deck (Virtual Concert Hall) Project

Utilizing hardware provided by the Intel grant, The Computer Music Department is developing a system with which a performer can rehearse in a practice room, and his instrument’s acoustic signal will be processed by NT workstations in such a way that the acoustics of a specific concert hall will be replicated. This is accomplished by the performer playing into a microphone, applying digital signal processing to the signal, and playing back signals into the practice room (through small multimedia speakers) which replicate the acoustics of a desired hall. Initial experiments with “off-the-shelf” processing equipment have been promising. We will, however, need to create models for specific concert halls and develop our own signal processing algorithms.
