An audio codec includes an input for receiving audio information. Audio processing circuitry produces a first stereo audio signal, a second stereo audio signal, and a monotone audio signal based on the audio information. A low pass filter filters 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 filters 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 filters 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. A summing module produces a tone controlled audio output.
