During production, at least one audio signal is processed in order to derive instructions for channel reconfiguring it. The at least one audio signal and the instructions are stored or transmitted. During consumption, the at least one audio signal is channel reconfigured in accordance with the instructions. Channel reconfiguring includes upmixing, downmixing, and spatial reconfiguration. By determining the channel reconfiguration instructions during production, processing resources during consumption are reduced.
Durant la phase de production, au moins un signal audio est traité de façon que des instructions de reconfiguration de canal puissent être dérivées. Ce signal audio et les instructions sont stockés ou transmis. Durant la phase de consommation, le signal audio est reconfiguré en fonction des instructions. La phase de reconfiguration de canal comprend un mélange-élévation, un mélange-abaissement et une reconfiguration spatiale. L'utilisation des instructions de reconfiguration durant la phase de production permet de réduire les besoins en ressources de traitement durant la phase de consommation.
