Abstract: The present invention provides methods and systems for digitally processing audio signals in two-channel audio systems and/or applications. In particular, the present invention includes a first filter structured to split a two-channel audio input signal into a low frequency signal and a higher frequency signal. A M/S splitter is then structured to split the higher frequency signal into a middle and a side signal. A detection module is then configured to create a detection signal from the middle signal, which is used in a compression module configured to modulate the side signal to create a gain-modulated side signal. A processing module is then structured to combine the low frequency signal, middle signal, and the gain-modulated side signal to form a final output signal.

Abstract: The present invention provides methods and systems for narrow bandwidth digital processing of an input audio signal. Particularly, the present invention includes a high pass filter configured to filter the input audio signal. A first compressor then modulates the filtered signal in order to create a partially processed signal.

A pass through module is configured to adjust the gain of the second signal. A mixer then combines the filtered first signal and the gain-adjusted second signal in order to output a combined signal. In some embodiments, a tone control module further processes the combined signal, and a second compressor further modulates the processed signal.

Abstract: The present invention provides for systems and methods for acquiring acoustic information from a resonating body. Specifically, a focused light beam is emitted from an emitter module onto an impedance matching reflector. The impedance matching reflector has similar wave propagation characteristics to the resonating body, so as to capture mechanical vibrations thereof. The impedance matching reflector reflects the focused light beam as it vibrates, and the vibrations are captured by a receiver module through the reflected light beam, which is converted to an input signal. The input signal may be further processed and converted to an audio output signal, as an accurate representation of the acoustic information emanating from within the resonating body.
