1. A method for processing a signal comprising:
- filtering the signal with a first low shelf filter, creating a filtered signal;
filtering the filtered signal with a first high shelf filter;
compressing the filtered signal with a first compressor;
processing the filtered signal with a graphic equalizer based at least in part on a material profile;
compressing the filtered signal with a second compressor; and
transmitting an output signal to a transducer.

Abstract
The present invention provides for methods and systems for digitally processing an audio signal to reproduce high quality sounds on various materials. In various embodiments, a method comprises filtering the signal with a low shelf filter and/or high shelf filter, passing the signal through a first compressor that, filtering the signal again with a low shelf filter and/or high shelf filter, processing the signal with a graphic equalizer based on a selected material profile, passing the signal through a second compressor, and outputting the signal to a transducer.
