Dynamic contoured-sound/subwoofer-synthesis audio system

A dynamic sound enhancement system that produces extreme low frequency sound, in the bass and sub-bass range, 50-250 Hz and below 50 Hz respectively, from all speaker and earpiece types including standard speakers, small speakers, personal earpieces, and hearing aids, that substantially compensates for the natural inadequacy of the human ear at both low and high frequencies, below 250 Hz and above 10,000 Hz respectively, and that substantially compensates for the frequency roll-off effects of standard speakers and other sound producing devices, comprising:

• a low frequency adjustment sub-system operable to provide a variety of low frequency responses in response to adjustments of an adjustable element, embodied with a plurality of step settings, each setting producing a different low frequency response thus allowing or preventing preferred low frequencies from reaching the system gain sub-system;
• a gain sub-system operable to invert input signal polarity, adjust the magnitude of applied frequencies dynamically, integrate feedback signals from other sub-systems with newly arriving input signals concurrently and present the resulting composite signal at its output;
• a low frequency feedback control sub-system operable to provide low frequency responses in relation to applied frequency thereby determining the bandwidth and magnitude of low frequency feedback signals applied to the input of the gain subsystem and contributing to regulation of bass and sub-bass frequency signal magnitude at the gain sub-system output;
• a low frequency phase offset sub-system operable to provide variable plus and minus feedback time offsets for preferred bass frequencies in relation to non-preferred frequencies embodied to produce time offsets encompassing up to several milliseconds of time which occur before (plus offset) and after (minus offset) in relation to non-preferred feedback frequencies;
• a band pass feedback control subsystem operable to provide a broad pass frequency band while concurrently attenuating the magnitude of applied feedback frequencies prior to conveying those frequencies to the gain sub-system thereby contributing to the regulation of system dynamic gain;
• a low frequency damping subsystem operable to provide supplementary regulation of the magnitude and shape of low frequency output signals thereby controlling sound producing device distortion artifacts by the method of controlling decay rate of the final output signal magnitude after the signal reaches a threshold gain defined in conjunction with a setting of the low frequency adjustment sub-system;
• a high frequency adjustment sub-system operable to provide a variety of high frequency responses in response to adjustments of an adjustable element, embodied with a plurality of step settings, each setting producing a different high frequency cutoff thus allowing or preventing preferred high frequencies from reaching the system gain sub-system;
• a high frequency damping subsystem operable to provide supplementary regulation of the magnitude and shape of high frequency output signals thereby controlling sound producing device distortion artifacts by the method of controlling decay rate of the final output signal magnitude after the signal reaches a threshold gain defined in conjunction with a setting of the high frequency adjustment sub-system, and
• a high frequency phase offset sub-system operable to provide variable plus and minus feedback time offsets for preferred treble frequencies in relation to non-preferred frequencies embodied to produce time offsets encompassing up to several milliseconds of time which occur before (plus offset) and after (minus offset) in relation to non-preferred feedback frequencies.
