"Impact of Compression on the Performance of the Room Impulse Response " by Hualin Ren, Christian Ritz et al.
In Virtual Reality (VR) an application where a user is able to move freely in the virtual or physical environment, the 3D sound scene reproduced over headphones, including the acoustic Room Impulse Response (RIR) must be constantly updated. Storing and transmitting the RIR for every possible source and listening position is impractical and hence efficient compression is required. This paper investigates compression and interpolation approaches for synthesising the RIR at new listening positions using a discrete set of compressed directional RIRs (DRIRs) recorded with an Ambisonics B-format mic...
