Claim 4:
5. A method for audio decoding, comprising:
receiving a spliced audio data stream, comprising:
a sequence of payload packets, each of the payload packets belonging to a respective one of a sequence of access units into which the spliced audio data stream is partitioned, each access unit being associated with a respective one of audio frames;
a truncation unit packet inserted into the spliced audio data stream and indicating an end portion of an audio frame with which a predetermined access unit is associated, as to be discarded in playout,
wherein in a first subsequence of payload packets of the sequence of payload packets, each payload packet belongs to an access unit of a first audio data stream having encoded thereinto a first audio signal in units of audio frames of the first audio signal, and the access units of the first audio data stream comprising the predetermined access unit, and in a second subsequence of payload packets of the sequence of payload packets, each payload packet belongs to access units of a second audio data stream having encoded thereinto a second audio signal in units of audio frames of the second audio data stream,
wherein the first and the second subsequences of payload packets are immediately consecutive with respect to each other and abut each other at the predetermined access unit and the end portion is a trailing end portion in case of the first subsequence preceding the second subsequence and a leading end portion in case of the second subsequence preceding the first subsequence, and

reconstructing from the access unit immediately succeeding the predetermined access unit and forming an onset of the access units of the second audio data stream, the respective associated audio frame independent from the predetermined access unit.
