The invention relates to a method for resampling an audio-frequency signal with an output sampling frequency, for a current signal frame. The method is used in the event that the preceding frame is sampled at a first sampling frequency which is different from a second sampling frequency of the current frame, and comprises the steps of determining a first segment (E301) and a second segment (E303) of the signal by adding samples to zero at the end of stored samples of the preceding frame and at the start of samples of the current frame, respectively; obtaining the first resampled segment (E302) and the second resampled segment (E304) by applying at least one resampling filter respectively to the first segment resampling the first frequency at the output frequency, and to the second segment resampling the second frequency at the output frequency; and combining (E305) the overlapping portion of the first and second resampled segments in order to obtain at least one portion of the resampled current frame. The invention is also useful for a resampling device and for a decoder comprising such a device. |
