Abstract

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.
