RESAMPLING AN AUDIO SIGNAL FOR LOW-LATTERY ENCODING / DECODING

Abstract

The invention relates to a process for resampling an audio frequency signal in an audio frequency signal encoding or decoding, characterized in that the process comprises the following steps per signal block to be resampled: determining by adaptive linear prediction a number of future signal samples, this number being determined according to a selected resampling delay, constructing a resampling support vector from at least the samples of the current block and the determined future signal samples, applying a resampling filter to the samples of the resampling support vector, the process also comprising the following steps: switching between two coding modes, resampling the current block of the signal resulting from the switching.The invention also relates to a resampling device implementing the described process, an encoder and a decoder comprising at least one device.
