Abstract

A system and method for digital processing including a gain element to process an input audio signal, a high pass filter to then filter the signal and create a high pass signal, a first filter module to filter the high pass signal and create a first filtered signal and a splitter to split the high pass signal into two high pass signals. The first filter module filters one high pass signals before a first compressor modulates the signal or a high pass signal to create a modulated signal. A second filter module filters the modulated signal to create a second filtered signal that is processed by a first processing module including a band splitter that splits the signal into low and high band signals that are then modulated by compressors. A second processing module processes the modulated low and high band signals to create an output signal.

Claims9

Dependent claims

A system for digital signal processing of an audio signal comprising:

a high pass filter configured to filter an audio signal to create a high pass signal,
a first filter module configured to filter the high pass signal to create a first filtered signal,
a first compressor configured to modulate the first filtered signal to create a modulated signal,
a second filter module configured to filter the modulated signal to create a second filtered signal,
a first processing module configured to process the second filtered signal to create a processed signal,
a band splitter configured to split the processed signal into at least a first low band signal and a second high band signal,
at least a first modulator structured to modulate said first band signal and a second modulator structured to modulate said second band signal to create a first and a second modulated band signal, and
a summing module configured to combine at least the first and second modulated band signals to create a combined signal.
