Patent

CA 2401798

The invention enables the inclusion of voice and remaining audio information at different parts of the audio production process. In particular, the invention embodies special techniques for VRA-capable digital mastering (510) and accommodations of VRA by thoseclasses of audio compression formats that sustain less losses of audio data as compared to any codecs that sustain comparable net losses equal or greater than the AC3 compression format. The invention facilitates an end-listener's voice-to-remaining audio (VRA) adjustment (535) upon the playback of digital audio media formats by focusing on new configurations of multiple parts of the entire digital audio system, thereby enabling a new technique intended to benefit audio end-users (end- listeners) who wish to control the ratio of the primary vocal/dialog content of an audio program relative to the remaining portion of the audio content in that program.

L'invention concerne un procédé permettant d'incorporer de la voix et des informations sonores restantes à différentes étapes du processus de production sonore. Plus particulièrement, le mode de réalisation décrit dans la présente invention concerne des techniques spéciales de gravure numérique à rapport voix/signal sonore restant (VRA), ainsi que l'adaptation du rapport voix/signal sonore par ces types de formats de compression sonore supportant moins les pertes de données sonores que n'importe quel compresseur-décompresseur supportant des pertes nettes comparables égales ou supérieures au format de compression AC3. Le procédé décrit dans cette invention permet à un auditeur final du rapport voix/signal sonore restant d'effectuer des réglages en fonction de la lecture des formats de médias sonores numériques en se concentrant sur les nouvelles configurations de plusieurs portions de l'ensemble du système sonore numérique. Ceci permet d'utiliser une nouvelle technique qui avantage les utilisateurs finals du signal sonore (les auditeurs finaux) souhaitant commander le rapport du contenu vocal/dialogue primaire d'un programme sonore et de la portion restante du contenu sonore dans ce programme.
