Sector-Based Parametric Sound Field Reproduction in the Circular Harmonic Domain Using Covariance Based Rendering

Parametric spatial audio rendering approaches are able to reproduce a recorded sound scene with high perceptual quality. Most approaches, however, assume a sound field model of a single plane wave plus a diffuse field component, an assumption which is often violated. Therefore, a sector-based reproduction method operating on higher-order spherical harmonic domain signals has been proposed. This paper provides an adaptation of this method to the circular harmonic domain. Furthermore, objective and subjective evaluations are performed, to identify particular strengths and weaknesses of the proposed method.
