  • Audio processing circuit and method
    Patent number: 7714750
    Abstract: An audio processing circuit includes a clock synthesizer, a clock divider, a digital interpolator module, a sampling rate converter and a digital-to-analog converter. The clock synthesizer generates a base clock signal according to a sampling clock signal and a first reference clock signal. The clock divider generates a multiple frequency clock signal according to the base clock signal. The digital interpolator module interpolates a digital audio data according to the multiple frequency clock signal. The sampling rate converter processes the interpolated digital audio data into a re-sampled digital audio data according to the multiple frequency clock signal and a second reference clock signal. The digital-to-analog converter is coupled to the sampling rate converter for converting the re-sampled digital audio data into an analog audio signal according to the second reference clock signal.
