Title (EN) NON-UNIFORM PARAMETER QUANTIZATION FOR ADVANCED COUPLING
(FR) QUANTIFICATION NON UNIFORME DE PARAMÈTRES POUR UN COUPLAGE AVANCÉ
Abstract: front page image
(EN)The present disclosure provides methods, devices and computer program products for non-uniform quantization of parameters relating to parametric spatial coding of audio signals. The disclosure further relates to a method and apparatus for reconstructing an audio object in an audio decoding system taking the non-uniformly quantized parameters into account. According to the disclosure, such an approach renders it possible to reduce bit consumption without substantially reducing the quality of the reconstructed audio object.
(FR)La présente invention concerne des procédés, des dispositifs et des produits de programme informatique pour une quantification non uniforme de paramètres relatifs à un codage spatial paramétrique de signaux audio. L'invention concerne en outre un procédé et un appareil pour reconstruire un objet audio dans un système de décodage audio en prenant en compte les paramètres quantifiés de façon non uniforme. Selon l'invention, une telle approche permet de réduire la consommation de bits sans réduire substantiellement la qualité de l'objet audio reconstruit.
