Abstract:
The present document discloses a method for fading discontinued audio feeds for replay by a speaker. In particular, the method may first comprise receiving an input audio feed comprising a plurality of samples. The method may further comprise determining whether the input audio feed is discontinued. And, when discontinuity of the input audio feed is detected, the method may comprise generating an intermediate audio signal comprising a plurality of samples based on the discontinued input audio feed. In particular, the intermediate audio signal may be generated based on a last portion of the discontinued input audio feed that has been output for replay. In addition, the method may further comprise applying a fadeout function to the intermediate audio signal to generate a fadeout audio signal. Finally, the method may comprise outputting the fadeout audio signal for replay by the speaker.
