Embodiment Construction

[0051] Detailed Description of Preferred Embodiments

[0052] Such as figure 1 As can be seen, the prior art conventional stereo system has a relatively narrow listening area 70'. For optimal stereo listening, the listener must be positioned exactly between the two speakers 60' in this embodiment.

[0053] As seen in FIG. 2, the multi-speaker sound imaging system 10 is a sound processing system defined as a multi-speaker imager (multi-speaker imager) 40, which consists of a source 30 that processes two-channel stereophonic FM signals and other media sources 20 drives. All other identifications of the multi-speaker imager 40 are defined as "MSI". The MSI 40 seen in Figures 3a and 3b illuminates a light source 44 when powered. The MSI 40 takes signals from conventional stereo sources via conductors 32, processes them, and delivers output signals via conductors 42 as an even number of four or more. An external two-channel or multi-channel amplifier 50 amplifies these signals...

Abstract

A sound imaging system (10), which by processing left and right stereo channel audio signals of a conventional two channel stereo system (30), distributes signals to a speaker array of a number of speakers (60) determined by a listening area (70). Listeners located in different places within the listening area (70), can have an audible perception of an equivalent distribution to that of the conventional two channel stereo system (30). Additionally they will have an audible central perception of the centered program material equivalent to that obtained from the conventional two channel stereo system (30) when the listeners are located in a median plane of the conventional two channel stereo system speakers(60').

Description

technical field [0001] The present invention relates to a multi-speaker sound imaging system, and more particularly, to an audio system for producing multi-channel imaging from two-channel recordings for improved user listening. Background technique [0002] Typically, music systems for recording, storage and reproduction utilize two-channel systems. The two-channel recording system basically works by mixing multiple instruments, vocals, effects and other sound signals, all of which produce two signals or channels as a result, which are then recorded in different media such as CDs, tapes, etc. In addition, two-channel amplifiers drive speakers to reproduce these signals for listening. [0003] The mixing process during two-channel recording is very important because in this process the relative spatial configuration of all musical components, such as instruments, vocals and all other sound signals, is defined. One purpose of stereophonic reproduction is to allow the liste...
