An audio decoder decodes a bit stream of encoded audio data, which bit stream represents a sequence of audio sample values and includes a plurality of frames, wherein each frame includes associated encoded audio sample values. The audio decoder includes a determiner configured to determine whether a frame of the encoded audio data is a special frame including encoded audio sample values associated with the special frame and additional information, wherein the additional information include encoded audio sample values of a number of frames preceding the special frame, wherein the encoded audio sample values of the preceding frames are encoded using the same codec configuration as the special frame, wherein the number of preceding frames is sufficient to initialize the decoder to be in a position to decode the audio sample values associated with the special frame if the special frame is the first frame upon start-up of the decoder.

A time scaler for providing a time scaled version of an input audio signal is configured to compute or estimate a quality of a time scaled version of the input audio signal obtainable by a time scaling of the input audio signal. The time scaler is configured to perform the time scaling of the input audio signal in dependence on the computation or estimation of the quality of the time scaled version of the input audio signal obtainable by the time scaling. An audio decoder has such a time scaler.

A transmission signal having a sequence of logical frames embed therein, is constructed such that each logical frame has a useful data section, wherein consecutive access units of an access unit stream are consecutively inserted into the useful data section of the sequence of logical frames, wherein each logical frame into which a begin of an access unit falls, has an access unit table having, per begin of the access units falling into the respective logical frame, a pointer pointing thereto.

An apparatus for processing stored data packets in a media data container and stored associated meta information in a metadata container, the associated meta information having transport timing information and location information indicating a storage location of the stored data packets in the media data container, the apparatus having a processor for determining, based on the stored data packets and the stored associated meta information, decoding information for a media payload of the stored data packets, wherein the decoding information indicates at which time instant to replay which payload of the stored data packets.
