Abstract
A method of encoding a multi-channel 3-dimensional (3D) audio signal mixed with a multi-channel 3D object signal is provided. The method includes: obtaining a location parameter indicating a virtual location of the multi-channel 3D object signal on a multi-channel speaker layout based on a gain value of the multi-channel 3D object signal for each channel; and encoding the multi-channel 3D audio signal and the location parameter.
Claims4
A method of audio rendering three-dimensional (3D) audio signals, the method comprising:
- receiving an audio signal of an object and multichannel audio signals including a height channel signal;
- receiving location information of the object, wherein the location information comprises height information;
- obtaining first gains for the multichannel audio signals based on a first layout which is formed by the multichannel audio signals and a second layout which is formed by a plurality of output channel signals;
- obtaining second gains for the audio signal of the object based on the location information of the object and the second layout;
- rendering the multichannel audio signals to provide a plurality of audio-channel signals representing 3D sound over the second layout based on the first gains;
- rendering the audio signal of the object to provide a plurality of object-channel signals representing 3D sound over the second layout based on the second gains;
- and
- generating the plurality of output channel signals by mixing the plurality of audio-channel signals and the plurality of object-channel signals,
- wherein the first layout and the second layout are independent of each other.
