ABSTRACT:
A single chip audio system100includes a bus interface101,digital to analog converters110,an analog mixer115,and analog spatial enhancement circuitry7500.Digital to analog converters110convert digital audio data received through bus interface101into analog signals. Analog mixer115mixes signals received from digital to analog converters110with an analog signal received from an external source. Analog spatial enhancement circuitry7500enhances first and second mixed analog signals output from analog mixer115.
