Methods and systems for rendering object based audio

A system for rendering audio content of an audio program, wherein the audio program is associated with a mix of the audio content, the system comprising:

• a receiver for receiving the audio program, the audio program further comprising mix metadata indicative of the mix of the audio content, wherein the mix of the audio content comprises:
• at least one of (1) one or more set(s) of object channels and (2) one or more bed(s) of speaker channels;
• a parser for parsing, by an audio processing unit, the one or more bed(s) of speaker channels and/or one or more set(s) of object channels and the mix metadata;
• a first processor for determining that the mix metadata is associated with the one or more bed(s) of speaker channels and/or the one or more set(s) of object channels;
• a second processor for determining, based on the mix metadata, rendering information for the one or more bed(s) of speaker channels;
• and
• a renderer for rendering the audio content based on the mix metadata, wherein the rendering comprises rendering the one or more bed(s) of speaker channels and/or the one or more set(s) of object channels based on the rendering information.

A method of generating an audio program, the method comprising:

• determining audio content, wherein the audio content comprises:
• one or more bed(s) of speaker channels and/or one or more set(s) of object channels;
• determining mix metadata indicative of at least a mix of the audio content, wherein the mix metadata is associated with the one or more bed(s) of speaker channels and/or the one or more set(s) of object channels;
• and
• generating the audio program, wherein the audio program comprises the audio content and the mix metadata, wherein the mix of the audio content comprises:
• at least one of (1) one or more set(s) of object channels and (2) one or more bed(s) of speaker channels.
