Document Type and Number:
WIPO Patent Application WO/2016/183379
Kind Code:
A3
Abstract:
Audio signals (201) are received. The audio signals include left and right surround channels (206). The audio signals are played back using far-field loudspeakers (101-108, 401-406) distributed around a space (111, 409) having a plurality of listener positions (112, 410). The left and right surround channels are played back by a pair of far-field loudspeakers (103, 106, 403, 405) arranged at opposite sides of the space having the plurality of listener positions. An audio component (208) coinciding with or approximating audio content common to the left and right surround channels is obtained. The audio component is played back using at least a pair of near-field transducers (109, 110, 407, 408) arranged at one of the listener positions. Associated systems (100, 400), methods (800) and computer program products are provided. Systems (300), methods (900) and computer program products providing a bitstream (303) comprising the audio signals and the audio component are also provided, as well as a computer-readable medium with data (700) representing such audio content.
