A process for combining audio channels combines the audio channels to produce a combined audio channel and dynamically applies one or more of time, phase, and amplitude or power adjustments to the channels, to the combined channel, or to both the channels and the combined channel. One or more of the adjustments are controlled at least in part by a measure of auditory events in one or more of the channels and/or the combined channel. Applications include the presentation of multichannel audio in cinemas and vehicles. Not only methods, but also corresponding computer program implementations and apparatus implementations are included.
Procédé servant à combiner des canaux audio afin de produire un canal audio combiné et consistant à appliquer de façon dynamique un ou plusieurs réglages de temps, de phase, d'amplitude ou de puissance à ces canaux, au canal combiné ou à la fois aux canaux et au canal combiné. Un ou plusieurs de ces réglages sont contrôlés au moins en partie par une mesure d'événements auditifs dans un ou plusieurs de ces canaux et/ou du canal combiné. Certaines applications consistent à présenter ce système audio à canaux multiples dans des cinémas ou des véhicules. L'invention ne concerne pas que des procédés, mais également des mises en application correspondantes de programme informatique et de dispositif.
