Device and method for processing signals associated with sound

摘要

A method and device may color or modify the tone or sound quality of audio input signals. A processor such as a DSP, may apply two or more filters to the audio input signal, each filter comprising a set of filter coefficients. The processor may combine finite impulse response (FIR) filters of the two or more filters into a power-saving filter. A speaker or sound emitter may emitting an output audio signal from the filtered audio input signal. The output audio signal has a different tone quality than that of the input audio signal.

1. A sound-processing method, comprising:
receiving an audio input signal from a musical instrument; applying two or more filters to the audio input signal, each filter comprising a set of filter coefficients; combining finite impulse response (FIR) filters of the two or more filters into a power-saving filter; and emitting an output audio signal from the filtered audio input signal, wherein the output audio signal has a different tone quality than that of the input audio signal.
