AB  - In applications such as surround sound reconstruction, the required information in nonindividualized head-related transfer functions (HRTF) can be reduced without producing audible degradation. Estimating the magnitude and interaural phase spectra per critical band is sufficient for transparent parameterization. When reconstructed by interpolation of parameters in the spectral domain, spatial resolution of about 10 degrees proved to be sufficient for high-quality binaural processing. High-frequency phase characteristics proved to be irrelevant, and low-frequency phase can be described only with interaural delay.
