Concept for audio encoding and decoding for audio channels and audio objects

A method of decoding encoded audio data, comprising:

• receiving the encoded audio data, the encoded audio data comprising either a plurality of encoded audio channels and a plurality of encoded audio objects and compressed metadata related to the plurality of audio objects, or a plurality of encoded audio channels without any encoded audio objects;
• core decoding
• the encoded audio data to acquire a plurality of decoded audio channels and a plurality of decoded audio objects, when the encoded audio data comprises the plurality of encoded audio channels and the plurality of encoded audio objects and the compressed metadata related to the plurality of encoded audio objects, or
• the plurality of encoded audio channels to acquire a plurality of decoded audio channels, when the encoded audio data comprises the plurality of encoded audio channels without any encoded audio objects;
• decompressing the compressed metadata to acquire decompressed metadata, when the encoded audio data comprises the plurality of encoded audio channels and the plurality of encoded audio objects and the compressed metadata related to the plurality of encoded audio objects,
• processing the plurality of decoded audio objects using the decompressed metadata, and the plurality of decoded audio channels to acquire a number of output audio channels comprising audio data from the plurality of decoded audio objects and the plurality of decoded audio channels, when the encoded audio data comprises the plurality of encoded audio channels and the plurality of encoded audio objects and the compressed metadata related to the plurality of encoded audio objects;
• and
• converting the number of output audio channels into an output format,
• wherein, in the method of decoding the encoded audio data,
• either the processing the plurality of decoded audio objects is bypassed and the plurality of decoded audio channels acquired by the core decoding is fed, as the output audio channels, into the converting, when the encoded audio data comprises the plurality of encoded audio channels without any audio objects,
• or the plurality of decoded audio objects and the plurality of decoded audio channels acquired by the core decoding are fed into processing the plurality of decoded audio objects, when the encoded audio data comprises the plurality of encoded audio channels and the plurality of encoded audio objects and the compressed metadata related to the plurality of encoded audio objects.

A non-transitory digital storage medium having stored thereon a computer program for performing a method of decoding encoded audio data, comprising:

• receiving the encoded audio data, the encoded audio data comprising either a plurality of encoded audio channels and a plurality of encoded audio objects and compressed metadata related to the plurality of audio objects, or a plurality of encoded audio channels without any encoded audio objects;
• core decoding
• the encoded audio data to acquire a plurality of decoded audio channels and a plurality of decoded audio objects, when the encoded audio data comprises the plurality of encoded audio channels and the plurality of encoded audio objects and the compressed metadata related to the plurality of encoded audio objects, or
• the plurality of encoded audio channels to acquire a plurality of decoded audio channels, when the encoded audio data comprises the plurality of encoded audio channels without any encoded audio objects;
• decompressing the compressed metadata to acquire decompressed metadata, when the encoded audio data comprises the plurality of encoded audio channels and the plurality of encoded audio objects and the compressed metadata related to the plurality of encoded audio objects,
• processing the plurality of decoded audio objects using the decompressed metadata, and the plurality of decoded audio channels to acquire a number of output audio channels comprising audio data from the plurality of decoded audio objects and the plurality of decoded audio channels, when the encoded audio data comprises the plurality of encoded audio channels and the plurality of encoded audio objects and the compressed metadata related to the plurality of encoded audio objects;
• and
• converting the number of output audio channels into an output format,
• wherein, in the method of decoding the encoded audio data,
• either the processing the plurality of decoded audio objects is bypassed and the plurality of decoded audio channels acquired by the core decoding is fed, as the output audio channels, into the converting, when the encoded audio data comprises the plurality of encoded audio channels without any audio objects,
• or the plurality of decoded audio objects and the plurality of decoded audio channels acquired by the core decoding are fed into processing the plurality of decoded audio objects, when the encoded audio data comprises the plurality of encoded audio channels and the plurality of encoded audio objects and the compressed metadata related to the plurality of encoded audio objects,
• when said computer program is run by a computer.
