A sound processing system receives a stereo signal which, by a segmenter (109) is divided into stereo time-frequency signal segments, each of which may correspond to a frequency domain sample in a given time segment. A decomposer (111) decomposes the time-frequency signal segments by for each pair of stereo time-frequency signal segments performing the steps of: determining a similarity measure indicative of a degree of similarity of the stereo time frequency signal segments; generating a sum time-frequency signal segment as a sum of the stereo time-frequency signal segments; and generating a centre time-frequency signal segment from the sum time-frequency signal segment and a pair of side stereo time-frequency segments from the pair of stereo time-frequency signal segments in response to the similarity measure. A signal generator (113) then generates a multi-channel signal comprising a centre signal generated from the sum time-frequency signal segments and side signals generated from the side stereo time-frequency segments.

A directional loudspeaker provides an enhanced listening environment by producing an indirect sound field of greater amplitude than that of the direct sound field. The directional loudspeaker includes loudspeaker elements positioned to provide a listener located below the loudspeaker elements with an impression of sound spaciousness in a vehicle environment. The loudspeaker elements may include baffles or acoustic lenses to deflect the indirect field away from the path to the listener position. The loudspeaker may also be operated with windows open by channeling the indirect sound field through an acoustic waveguide and deflector to the listener. A sound processor is also provided to accept a sound input, create an indirect and direct sound field, output the sound fields to loudspeaker elements, and also may provide electronic enhancement effects such as multi-channel sound or sound parameter adjustment.

A spatial audio processing apparatus comprises a receiver (101) for receiving audio scene data describing an audio scene comprising spatial audio components and associated position data. The audio components may be provided as audio objects. A distance unit (105) provides a position indication which includes a focus distance that is indicative of a distance from a reference position in the audio scene. An adapter (103) adapts a perceptual emphasis property, such as an audio level, frequency distribution, or degree of diffuseness, of a spatial audio component relative to at least one other spatial audio component of the audio scene in response to a difference measure reflecting a difference between the focus distance and a distance in the audio scene from the reference position to a position of the spatial audio component. An audio renderer (107) renders the resulting audio scene using the received position data. The approach may emphasize audio at the focus distance in the audio scene.
