Resampling An Audio Signal For Low Delay Encoding/Decoding
Abstract: The invention relates to a method for resampling an audio frequency signal in an audio frequency signal encoding or decoding operation. The method is such that it comprises the following steps per signal block to be resampled: determining (E401) by adaptive linear prediction a number of future signal samples this number being defined on the basis of a chosen 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 device implementing the described method and an encoder and decoder comprising at least one device.
