摘要： Embodiments are described for rendering spatial audio content through a system that is configured to reflect audio off of one or more surfaces of a listening environment. The system includes an array of audio drivers distributed around a room, wherein at least one driver of the array of drivers is configured to project sound waves toward one or more surfaces of the listening environment for reflection to a listening area within the listening environment and a renderer configured to receive and process audio streams and one or more metadata sets that are associated with each of the audio streams and that specify a playback location in the listening environment.

In particular, the system comprises a transmitter for transmitting a left channel (L) signal and a right channel (R) signal to a speaker. The speaker comprises a processing unit configured to (a) receive an audio signal having a left channel (L) signal and a right channel (R) signal; (b) process separately and independently the L and R audio signals to produce processed signals; and (c) mix the processed signals to produce the surround sound signal.

摘要： In some embodiments, a method for upmixing input audio comprising N full range channels to generate 3D output audio comprising N+M full range channels, where the N+M full range channels are intended to be rendered by speakers including at least two speakers at different distances from the listener. The N channel input audio is a 2D audio program whose N full range channels are intended for rendering by N speakers nominally equidistant from the listener. The upmixing of the input audio to generate the 3D output audio is typically performed in an automated manner, in response to cues determined in automated fashion from stereoscopic 3D video corresponding to the input audio, or in response to cues determined in automated fashion from the input audio. Other aspects include a system configured to perform, and a computer readable medium which stores code for implementing any embodiment of the inventive method.
