System and method for digital signal processing

A method for processing a digital signal comprising:

• adjusting a gain or the digital signal a first time using a digital processing device to create a first adjusted signal;
• processing the first adjusted signal with a first low shelf filter and a first high shelf filter, using a second digital processing device, in order to create a first filtered signal;
• compressing the first filtered signal with a first compressor, using a third digital processing device, in order to create a first compressed signal;
• processing the first compressed signal with a second low shelf filter and a second high shelf filter, using a fourth digital processing device, in order to create a second filtered signal;
• processing the second filtered signal with a graphic equalizer, using a fifth digital processing device, in order to create an equalized signal;
• compressing the equalized signal with a second compressor, using a sixth digital processing device, in order to create a second compressed signal;
• adjusting the gain of the second compressed signal a second time, using a seventh digital processing device, in order to create a second adjusted signal, wherein the adjustment comprises a gain reduction if the gain of the second compressed signal is above a predetermined threshold;
• outputting the second adjusted signal, from an eighth digital processing device through an amplifier and driver circuit in a personal audio listening device.
