Abstract:
The invention discloses rendering sound field signals, such as Higher-Order Ambisonics (HOA), for arbitrary loudspeaker setups, where the rendering results in highly improved localization properties and is energy preserving. This is obtained by a new type of decode matrix for sound field data, and a new way to obtain the decode matrix. In a method for rendering an audio sound field representation for arbitrary spatial loudspeaker setups, the decode matrix (D) for the rendering to a given arrangement of target loudspeakers is obtained by steps of obtaining a number (L) of target speakers, their positions ( L ), positions ( S ) of a spherical modeling grid and a HOA order (N), generating ( 141 ) a mix matrix (G) from the positions ( S ) of the modeling grid and the positions ( L ) of the speakers, generating ( 142 ) a mode matrix ({tilde over (Ψ)}) from the positions ( S ) of the spherical modeling grid and the HOA order, calculating ( 143 ) a first decode matrix ({circumflex over (D)}) from the mix matrix (G) and the mode matrix ({tilde over (Ψ)}) and smoothing and scaling ( 144,145 ) the first decode matrix ({circumflex over (D)}) with smoothing and scaling coefficients.

Claim (Index 2):
The method of  claim 1 , further comprising\n buffering and serializing the spatial signal W, wherein time samples w(t) for a plurality of channels are obtained; and delaying time samples w(t) individually for each of the channels in delay lines, wherein corresponding digital signals are obtained, wherein the delay lines compensate different loudspeaker distances.
