Classification: CPC G  H | IPC G  H

Claim 8:
9. A decoding method, comprising:
outputting, by a Unified Speech and Audio Coding (USAC) three-dimensional (3D) decoder, channel signals and object signals, wherein the object signals including discrete object signals;
decoding, by an object metadata (OAM) decoder, an object metadata; and
generating, by an object renderer, an object waveform according to a given reproduction format using the object metadata, wherein the each of the object signals is rendered into output channel signals for loudspeakers based upon the object metadata,
wherein when an arrangement of the loudspeakers is not spherical, time compensation and level compensation is performed for the arrangement of the loudspeakers,
wherein the channel signals are controlled based on control information to control a volume or a gain of the channel signals, control information to control a horizontal rotation of the channel signals, and control information to control a vertical rotation of the channel signals.
