1. A method for encoding time marking information within audio data, wherein the audio data is a bitstream, the method comprising:

  • encoding time marking information as audio metadata within the audio data, thereby forming a joint bitstream, wherein the time marking information indicates a plurality of sections of an audio object in the audio data;

    wherein the time marking information is encoded in multiple positions of the audio data;

    wherein the multiple positions occur at a particular occurrence rate in the audio data bitstream;

    wherein time marking information in a given position of the multiple positions is specified in relation to the occurrence of the given position in the audio data bitstream; and

    wherein the time marking information is encoded in a metadata container of the joint bitstream;

    thereby enabling a corresponding decoder to start playback of the audio object at a beginning of a section of the audio object indicated by the time marking information.
