Patent

CA 2077662

The invention relates in general to the recording, transmitting, and reproducing of multidimensional sound fields intended for human hearing. More particularly, the invention relates to subband encoding and decoding of signals representing such sound fields, wherein the encoded signals may be carried by multiple discrete signals and/or a composite signal with a control signal conveying either the relative levels of the encoded signals, or the apparent direction of the sound field represented by the encoded signals. In digital implementations, adaptive bit allocation may be used to reduce the informational requirements of the encoded signals.

L'invention se rapporte en général à l'enregistrement, la transmission et la reproduction de champs sonores à dimensions multiples destinés à l'audition humaine. Plus particulièrement, l'invention se rapporte au codage et au décodage par bandes subdivisées de signaux représentant de tels champs sonores, les signaux codés pouvant être portés par des signaux discrets multiples et/ou un signal composite, et un signal de commande indiquant soit les niveaux relatifs des signaux codés, soit la direction apparente du champ sonore représenté par les signaux codés. Dans des modes de réalisation numériques, des affectations de bits adaptatives peuvent être utilisées pour réduire les besoins en informations des signaux codés.
