Patent

CA 2744429

A converter and con-version method are disclosed for converting N channel audio input chan-nels into M channel audio output channels, wherein a processor is used for applying a transfer function to a signal received on an input channel to obtain reverberation components of a calculated output channel, wherein said transfer function is a simplified transfer function matching a selected subset of a set of local maxima of a measured reverberation when applied to a corresponding stimulus.

L'invention porte sur un convertisseur et sur un procédé de conversion pour convertir des canaux d'entrée audio à N canaux en canaux de sortie audio à M canaux, un processeur étant utilisé pour appliquer une fonction de transfert à un signal reçu sur un canal d'entrée pour obtenir des composantes de réverbération d'un canal de sortie calculé, ladite fonction de transfert étant une fonction de transfert simplifiée correspondant à un sous-ensemble sélectionné d'un ensemble de maxima locaux d'une réverbération mesurée lorsqu'elle est appliquée à un stimulus correspondant.
