| description | The invention is directed to a method, which comprises receiving audio reproduction data comprising one or more audio objects and metadata associated with each of the one or more audio objects; receiving reproduction environment data comprising an indication of a number of reproduction speakers in the reproduction environment and an indication of the location of each reproduction speaker within the reproduction environment; and rendering the audio objects into one or more speaker feed signals by applying an amplitude panning process to each audio object, wherein the amplitude panning process is based, at least in part, on the metadata associated with each audio object and the location of each reproduction speaker within the reproduction environment, and wherein each speaker feed signal corresponds to at least one of the reproduction speakers within the reproduction environment. The metadata associated with each audio object includes audio object coordinates indicating the intended reproduction position of the audio object within the reproduction environment and zone constraint metadata indicating whether rendering the audio object involves imposing speaker zone constraints. |
