RESAMPLING AN AUDIO SIGNAL FOR LOW-LATTERY ENCODING / DECODING

Abstract

The invention relates to a process for resampling an audio frequency signal in an encoding or decoding of the audio frequency signal. The process is such that it comprises the following steps per block of signal intended for resampling: - determining (E401) by adaptive linear prediction a number of future signal samples, this number being determined according to a selected resampling delay, - constructing (E402) a resampling support vector from at least the samples of the current block and the determined future signal samples, - applying (E403) a resampling filter to the samples of the resampling support vector. The invention also relates to a resampling mechanism implementing the described process, an encoder and a decoder comprising at least one device.
