Problems solved by technology

Many of these types of psychoacoustic signal processors have been used primarily to help with some of the problems associated with stereo, and are sometimes used in mono and discrete signal applications, but often not in the primary way

Embodiment Construction

[0053] Reference will now be made in detail to the exemplary embodiments of the invention illustrated in the accompanying drawings.

[0054] This application shows and discloses two exemplary embodiments for achieving a substantially complete audio signal in accordance with the principles of the invention. One exemplary embodiment shows passive signals, while the second embodiment shows active signals. Those skilled in the art will appreciate that the parameters are not fixed to any particular frequency setting or filter type. Filters are also not limited to angles or degrees such as 6dB, 12dB, 18dB or 24dB. Also, frequency settings such as 100 Hz for low pass or 16 kHz for high pass are examples for illustration purposes only.

[0055] Attached figure 1 A block diagram showing a passive configuration that works with speakers connected to an audio amplifier, without active circuitry. A mono or discrete signal source 10 applies a discrete source signal to a first audio ampl...

Abstract

The present invention relates to an apparatus and method for redeeming otherwise closed and concealed information contained in audio signals. An active circuit balances the ratio between in-phase and out-of-phase signals through the application of sum and difference signals and adjusts the ratio of gain in stereophonic signals as well as in monophonic and multichannel signal applications. This includes both the primary reference signal, and a plurality of redundant duplicate signals, substantially identical in all respects to the primary reference signal except in relation to magnitude and phase, for the purpose of unfolding, or opening the audio signal content. A pair of output signal levels approximates the golden ratio where the golden ratio is one plus the square root of five divided by two which gives an irrational number 1.618.

Description

[0001] This application is a continuation-in-part of Application No. 12 / 585411 filed September 11, 2009, which is incorporated by reference into this application as if it were fully disclosed by this application. Background technique [0002] The present invention relates to a method and apparatus for creating a substantially complete audio signal, and more particularly to a method for recovering information from discrete audio signals to reconstruct or generate substantially complete, nearly omnidirectional sound events Methods and equipment. [0003] Sound exists as pressure and velocity in a medium such as air. Sound begins with mechanical perturbations such as speech, a door slamming, a bow scraping a violin string, and so on. The vibration of the sound source causes the formation or pattern of sound waves. Sound waves propagate in various directions, such as three-dimensionally, omnidirectionally, and spherically. It is these moving sound waves that are heard as sound....
