A method for resampling an audio-frequency signal with an output sampling frequency, for a current signal frame. The method is used when the preceding frame is sampled at a first sampling frequency which is different from a second sampling frequency of the current frame. The method includes: determining a first and second segments of the signal by adding samples at 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 and the second resampled segment 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 the overlapping portion of the first and second resampled segments to obtain at least one portion of the resampled current frame.
A method for resampling of an audio frequency signal at an output sampling frequency, wherein the method comprises the following acts performed by a processing device of an audio coder or decoder:
An audio coder or decoder device for resampling an audio frequency signal at an output sampling frequency, wherein the device comprises:
A non-transitory processor-readable storage medium, on which is stored a computer program comprising code instructions for executing a resampling method for resampling of an audio frequency signal at an output sampling frequency, when the instructions are executed by a processor of a processing device of an audio coder or decoder, the instructions comprises:
