Abstract:
1. A signal processing system for use with an audio system, including a plurality of audio channels, each channel associated with at least one amplifier and at least one electro-acoustic transducer, said electro-acoustic transducer of each channel being positionable relative to at least one other such transducer of the plurality of audio channels so as to enable perception, on the part of a listener positioned relative to said transducers, of a sonic presentation creatable by audio signals carried by said plurality of channels and reproducible using said transducers, the sonic presentation having tonal aspects, including frequency and overload-amplitude-induced frequency distortion aspects, and spatial aspects, including some image and directional-cue aspects, and the audio system having a power capability of each channel without introduction of audible tonal distortion due to overload and a total power capability of the system including the power capability of all the channels combined without introduction of audible tonal distortion due to overload; at least one signal level threshold associated with at least one of said plurality of audio channels; a signal processor enabling manipulating the audio signals in the channels for dynamic power sharing in the audio system, responsive to said at least one threshold, such that upon a signal in at least one channel reaching said at least one threshold associated therewith, at least a portion of the audio signal in said at least one channel is routed to and mixed with an audio signal in at least one other channel, so that the signal level in the said at least one channel does not go so high as to give rise to an increase in audible tonal distortion due to overload, said routing taking into account the relative positions of the transducers associated with said channels in light of said perception on the part of said listener; the processor being so configured that in such manipulation the preservation of the fidelity of reproduction of said sonic presentation is a priority.
