Application of Wave Field Synthesis and Analysis on Automotive Audio
AES Convention 131 · Paper 31 · October 2011
Abstract
High-quality audio equipment in cars enjoys rising popularity. For a remarkable number of people the car compartment represents the primary listening environment for enjoying music playback. Besides excellent sound quality spatial audio capabilities can also be expected from today’s top systems. In this talk we will give insight into the implementation of a spatial audio system based on Wave Field Synthesis that was realized inside an SUV. Audi AG and Fraunhofer IDMT together present the outcome of their research collaboration named "Audi Sound Concept." The Audi Q7 prototype has, on the one hand, remained a series production vehicle on the exterior, while on the other hand been rebuilt into a HiFi-Studio in the interior. The talk will include a systematic overview, a description of the playback-system, and some remarks about sound field analysis based on array measurements.
