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.
