System and method for digital signal processing

摘要

The present invention provides methods and systems for digital processing of an input audio signal. Specifically, the present invention includes a high pass filter configured to filter the input audio signal to create a high pass signal. A first filter module then filters the high pass signal to create a first filtered signal. A first compressor modulates the first filtered signal to create a modulated signal. A second filter module then filters the modulated signal to create a second filtered signal. The second filtered signal is processed by a first processing module. A band splitter splits the processed signal into low band, mid band, and high band signals. The low band and high band signals are modulated by respective compressors. A second processing module further processes the modulated low band, mid band, and modulated high band signals to create an output signal.

1. A system for digital signal processing of an input audio signal comprising:
a high pass filter configured to filter the input 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 a low band signal, a mid band signal, and a high band signal, a low band compressor configured to modulate the low band signal to create a modulated low band signal, a high band compressor configured to modulate the high band signal to create a modulated high band signal, and a second processing module configured to combine the modulated low band signal, the mid band signal, and the modulated high band signal to create an output signal.
