ABSTRACT:
The present invention is a method and apparatus for providing stereo audio signals is disclosed. The circuit for providing stereo audio signals comprises an interface circuit coupled to receive an audio signal. The interface circuit has an analog-to-digital converter for digitizing the audio signal to provide a first audio input signal and a second audio input signal. A first processing circuit coupled to the interface circuit is configured to generate a first audio output signal based on the first audio input signal. A second processing circuit coupled to the interface circuit is configured to generate a second audio output signal based on the second audio input signal. The circuit further comprises a processor coupled to the interface circuit and a memory for storing instruction sequences. The processor executes the stored instruction sequences, wherein the stored instruction sequences include process steps to cause the processor to generate a third audio input signal based on the first and the second audio input signals. A third processing circuit coupled to the processor is configured to generate a third audio output signal based on the third audio input signal.
