Claim 0:
1. A method for audio decoding, comprising:
receiving a spliceable 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 spliceable audio data stream is partitioned, each access unit being associated with a respective one of audio frames of an audio signal which is encoded into the spliceable audio data stream in units of the audio frames; and
a truncation unit packet inserted into the spliceable audio data stream and being settable so as to indicate, for a predetermined access unit, an end portion of an audio frame with which the predetermined access unit is associated, as to be discarded in playout,
a further predetermined access unit which has encoded thereinto the respective associated audio frame in a manner so that the reconstruction thereof at decoding side is independent from the access unit immediately preceding the further predetermined access unit, thereby allowing immediate playout,

decoding the audio signal from the access units with
discarding, for the predetermined access unit, the end portion of the audio frame with which the predetermined access unit is associated, in playout, and
reconstructing, from the further predetermined access unit, the respective associated audio frame independent from the access unit immediately preceding the further predetermined access unit.
