Audio codec producing a tone controlled output

1. An audio codec comprises:

an input for receiving audio information;

audio processing circuitry operably coupled to produce a first stereo audio signal, a second stereo audio signal, and a monotone audio signal based on the audio information;

a low pass filter operably coupled to filter the monotone audio output, wherein the low pass filter passes a bass component of the monotone audio signal substantially unattenuated and attenuates higher frequency components of the monotone audio signal;

a high pass filter operably coupled to filter the first stereo audio output, wherein the high passes filter passes a treble component of the first stereo audio signal substantially unattenuated and attenuates lower frequency components of the first stereo audio signal;

a band pass filter operably coupled to filter the second stereo audio output, wherein the band pass filter passes a mid band component of the second audio signal substantially unattenuated and attenuates low frequency components and high frequency components of the second stereo audio signal; and

a summing module operably coupled to sum the bass component, the treble component, and the mid band component to produce a tone controlled audio output.

2. The audio codec of claim 1 , wherein at least one of the low pass filter, the high pass filter, and the band pass filter further comprise a frequency response customized based on parameters of a sound system including the audio codec.

3. The audio codec of claim 1 , wherein the summing module further comprises an operational amplifier having a first input, a second input, and an output, wherein the first input is operably coupled to a reference voltage and the second input is operably coupled to sum the bass component, the treble component, and the mid band component.

4. An audio codec comprises:

an input for receiving audio information;

audio processing circuitry operably coupled to produce a first stereo audio signal and a second stereo audio signal based on the audio information;

a notch filter operably coupled to filter the first stereo audio signal, wherein the notch filter passes a bass component and a treble component of the first stereo audio signal and attenuates a mid-band component of the first stereo audio signal to produce a notched audio output;

a band pass filter operably coupled to filter the second stereo audio signal, wherein the band pass filter passes a mid-band component of the second stereo audio signal and attenuates a bass component and a treble component of the second stereo audio signal to produce a band pass audio output; and

a summing module operably coupled to sum the notched audio output and the band pass audio output to produce a tone controlled audio output.

5. The audio codec of claim 4 , wherein at least one of the notch filter and the band pass filter further comprise a frequency response customized based on parameters of a sound system including the audio codec.

6. The audio codec of claim 4 , wherein the summing module further comprises an operational amplifier having a first input, a second input, and an output, wherein the first input is operably coupled to a reference voltage and the second input is operably coupled to sum the bass component, the treble component, and the mid band component.
