System and method for dynamic recovery of audio data

A system for processing audio data comprising:

• a first system configured to receive an input audio data signal and to electronically process the input audio data signal to generate level normalized audio data;
• a second system configured to receive the level normalized audio data and to electronically process the level normalized audio data to generate a double sideband AM signal;
• and
• a third system configured to receive the double sideband AM signal and to mix the double sideband AM signal with the input audio data to generate primary audio data frequency components having double sideband AM signal side components
• wherein the first system comprises a first automatic gain control processor configured to receive the input audio data signal to remove a DC component of the input audio data signal;
• wherein the first system comprises a second automatic gain control processor coupled to the first automatic gain control processor and configured to receive the DC-compensated audio data signal and the input audio data signal and to generate the level normalized audio data;
• wherein the first system comprises a high pass filter coupled to the second automatic gain control processor and configured to receive the level normalized audio data and to generate high-pass filtered level normalized audio data;
• wherein the first system comprises a low pass filter coupled to the high pass filter and configured to receive the high-pass filtered level normalized audio data and to generate band-pass filtered normalized audio data;
• wherein the first system comprises a Hilbert transform coupled the low pass filter and to a square-add processor, the Hilbert transform configured to receive the band pass filtered normalized audio data and to form a Bedrosian all pass pair, the square-add processor configured to yield an instantaneous magnitude envelope detector.
