Abstract

An audio data-processing device (110), comprising a processing unit (111) adapted to generate at least one audio data transition segment (204) representing a transition between a preceding one of a plurality of audio data items (201) and a subsequent one of the plurality of audio data items (202), wherein each audio data transition segment (204) is generated on the basis of a portion of the corresponding preceding one of the audio data items (201) and on the basis of a portion of the corresponding subsequent one of the audio data items (202), and a sending interface (112) at which the at least one audio data transition segment (204) can be provided for transmission to an audio playback device (120).
