Virtual Venues—An All-Pass Based Time-Variant Artificial Reverberation System for Automotive Applications

Document Thumbnail

This paper presents an arti?cial reverberation system for automotive applications. The core reverberation algorithm is based on a time-variant all-pass ?lter and delay network. It supports an arbitrary number of de-correlated ambience channels and enables the creation of individual direction-dependent early re?ection patterns for each output channel. Incorporating de-reverberation technology and microphones, the system allows for 3D direct-ambience upmixing of stereo content simulating the acoustics of existing concert halls as well as for actively modifying and improving the acoustics of car interiors. Ambisonics measurements of real rooms and concert halls serve as starting point for designing the virtual rooms. Adaptive effect stabilization guarantees a consistent spatial impression in presence of masking driving noise.
