Grouping and transport of audio objects

A method for rendering audio signals associated with a plurality of audio objects within at least one audio scene, the method comprising:

• determining a grouping comprising at least two of the plurality of audio objects and at least one further audio object of the plurality of audio objects outside of the grouping;
• determining with respect to the grouping at least one first rendering parameter and/or rendering parameter rule type;
• rendering audio signals associated with the at least two of the plurality of audio objects by commonly applying the at least one first rendering parameter and/or rendering parameter rule type with respect to audio signals associated with the at least two of the plurality of audio objects;
• rendering audio signals associated with the at least one further audio object of the plurality of audio objects by individually and separately applying the at least one first rendering parameter and/or rendering parameter rule type with respect to each of the at least one further audio object;
• and
• combining the rendering of audio signals associated with the at least two of the plurality of audio objects with the rendering of audio signals associated with the at least one further audio object of the plurality of audio objects outside of the grouping.

An apparatus for rendering audio signals associated with a plurality of audio objects within at least one audio scene, the apparatus comprising at least one processor and memory storing program code, the memory and the program code configured, upon execution by the at least one processor, to:

• determine a grouping comprising at least two of the plurality of audio objects and at least one further audio object of the plurality of audio objects outside of the grouping;
• determine with respect to the grouping at least one first rendering parameter and/or rendering parameter rule type;
• render audio signals associated with the at least two of the plurality of audio objects by commonly applying the at least one first rendering parameter and/or rendering parameter rule type with respect to audio signals associated with the at least two of the plurality of audio objects;
• render audio signals associated with the at least one further audio object of the plurality of audio objects outside of the grouping by individually and separately applying the at least one first rendering parameter and/or rendering parameter rule type with respect to each of the at least one further audio object;
• and
• combine the rendering of audio signals associated with the at least two of the plurality of audio objects with the rendering of audio signals associated with the at least one further audio object of the plurality of audio objects outside of the grouping.
