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 low shelf filter configured to filter the high pass signal to create a first low shelf signal,a first high shelf filter configured to filter the first low shelf signal to create the first filtered signal.a first compressor configured to modulate the first filtered signal to create a modulated signal,a second low shelf filter configured to between 100 Hz to 3000 Hz and −

    5 dB to −

    20 dB to filter the modulated signal to create a second low shelf signal,a second high shelf filter configured to between 100 Hz to 3000 Hz and +5 dB to +20 dB to filter the second low shelf signal to create the second filtered signal,a first processing module configured to process 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, anda second processing module configured to process the modulated low band signal, the mid band signal, and the modulated high band signal to create an output signal.
