Audio encoder, method for providing an encoded representation of an audio information, computer program and encoded audio representation using immediate playout frames

A method for providing an encoded representation of an audio information on the basis of an input audio information, the method comprising:

• encoding a sequence of audio frames;
• providing one or more immediate playout frames comprising a representation of a current audio frame and encoded representations of one or more audio frames preceding the current audio frame;
• providing the representation of the current frame and the representations of the one or more audio frames preceding the current audio frame such that the representation of the current frame and the representations of the one or more audio frames preceding the current audio frame are decodable using a same decoder configuration, and
• providing the representations of the one or more audio frames preceding the current audio frame, which are included into the immediate playout frame, using a modified encoding functionality which is adapted to encode an audio frame using a smaller number of bits than a normal encoding functionality which is used for the encoding of the current audio frame.

A non-transitory digital storage medium having a computer program stored that when executed by a computer process provides an encoded representation of an audio information on the basis of an input audio information by:

• encoding a sequence of audio frames;
• providing one or more immediate playout frames comprising a representation of a current audio frame and encoded representations of one or more audio frames preceding the current audio frame;
• providing the representation of the current frame and the representations of the one or more audio frames preceding the current audio frame such that the representation of the current frame and the representations of the one or more audio frames preceding the current audio frame are decodable using a same decoder configuration, and
• providing the representations of the one or more audio frames preceding the current audio frame, which are included into the immediate playout frame, using a modified encoding functionality which is adapted to encode an audio frame using a smaller number of bits than a normal encoding functionality which is used for the encoding of the current audio frame.

An encoded audio representation comprising:

• a sequence of encoded audio frames;
• and
• one or more immediate playout frames comprising a representation of a current audio frame and encoded representations of one or more audio frames preceding the current audio frame,
• wherein the representation of the current frame and the representations of the one or more audio frames preceding the current audio frame are decodable using a same decoder configuration, and
• wherein the representations of the one or more audio frames preceding the current audio frame, which are included into the immediate playout frame, are provided using a modified encoding functionality which is adapted to encode an audio frame using a smaller number of bits than a normal encoding functionality which is used for the encoding of the current audio frame, or
• wherein the encoded representations of the one or more audio frames preceding the current audio frame, which are included into the immediate playout frame, comprise a smaller number of bits than the encoded representation of the current frame.
