Multiple-Loudspeaker Playback of Stereo Signals
A perceptually motivated spatial decomposition for two-channel stereo audio signals, capturing the information about the virtual sound stage, is proposed. The spatial decomposition allows resynthesizing audio signals for playback over sound systems other than twochannel stereo. With the use of more front loudspeakers the width of the virtual sound stage can be increased beyond ±30° and the sweet-spot region is extended. Optionally, lateral independent sound components can be played back separately over loudspeakers on the sides of a listener to increase listener envelopment. It is also explained how the spatial decomposition can be used with surround sound and wavefield synthesis–based audio systems.
