Patent ID: 6931139

Claim:
A computer audio system comprises: an audio codec operably coupled to receive audio information and to provide a first stereo audio output, a second stereo audio output, and a monotone audio output based on the audio information; and a tone controller operably coupled to the audio codec, wherein the tone controller includes: 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 output substantially unattenuated and attenuates higher frequency components of the monotone audio output; 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 output 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 output 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; wherein the audio codec includes: a first left channel volume controller operably coupled to adjust volume of a left channel of the first stereo audio output based on a first stereo volume setting of the audio information; a first right channel volume controller operably coupled to adjust volume of a right channel of the first stereo audio output based on the first stereo volume setting; a second left channel volume controller operably coupled to adjust volume of a left channel of the second stereo audio output based on a second stereo volume setting of the audio information; a second right channel volume controller operably coupled to adjust volume of a right channel of the second stereo audio output based on the second stereo volume setting; and a monotone volume controller operably coupled to adjust volume of the monotone audio output based on a monotone volume setting of the audio information, wherein adjustments of the monotone volume setting adjusts the bass component of the tone controlled audio output, wherein adjustments to the first stereo volume setting adjusts the treble component of the tone controlled audio output, and wherein adjustments to the second stereo volume setting adjusts the mid band component of the tone controlled audio output.
