SUpDEq - Spatial Upsampling by directional Equalization

Summary
Spatio-temporal spectral equalization of spherically measured head-related transfer function
Technology Benefits
Drastic reduction of the measuring effort and the measuring duration
Drastic reduction of computational effort in binaural synthesis
Outstanding playback quality
User-customized individualization of head geometries possible
Technology Application
Headphone-based 3D audio
Head-mounted displays
Lifelike audio reproduction of sound events in clubs, concert halls, opera houses and sports stadiums
Silent Disco / Quiet Clubbing
Virtual Reality
Augmented Reality
Detailed Technology Description
Based on the spatial-temporal-spectral equalization of the spherical data sets. This shifts the energy of the HRTF ( head-related transfer functions) sets in the SH domain to much smaller orders. A much lower spatial order can be used for measurement, storage and interpolation. The effort for the measurement and storage of an HRTF record is thus significantly reduced.
