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.

Claim (Index 6):
A method of audio rendering three-dimensional (3D) audio signals, the method comprising:\n receiving multichannel audio signals including a height channel signal; 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; rendering the multichannel audio signals to provide a plurality of audio-channel signals representing three-dimensional (3D) sound over the second layout based on the first gains; receiving location information of an audio object signal, including height information of the audio object signal; receiving a spatial parameter including at least one of an object level difference (OLD), an inter-object cross-correlation (IOC), and a downmix gain (DMG); obtaining second gains for the audio object signal based on the location information of the object and the second layout; rendering an audio object signal, reconstructed by using the spatial parameter, 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.
