Techniques and tools are described for processing reconstructed audio signals. For example, a reconstructed audio signal is filtered in the time domain using filter coefficients that are calculated, at least in part, in the frequency domain. As another example, producing a set of filter coefficients for filtering a reconstructed audio signal includes clipping one or more peaks of a set of coefficient values. As yet another example, for a sub-band codec, in a frequency region near an intersection between two sub-bands, a reconstructed composite signal is enhanced.
L'invention concerne des techniques et des dispositifs permettant de traiter des signaux audio reconstruits. Elle permet par exemple de filtrer un signal audio reconstruit dans le domaine temporel au moyen de coefficients de filtre qui sont calculés, au moins en partie, dans le domaine fréquentiel; ou de produire un ensemble de coefficients de filtre pour filtrer un signal audio reconstruit, grâce à l'écrêtage d'une ou de plusieurs crêtes d'un ensemble de valeurs de coefficient; ou encore, pour un codec de sous-bandes, d'améliorer le signal composite reconstruit dans une région de fréquence proche de l'intersection entre deux sous-bandes.
