Abstract
A single chip audio system 100 includes a bus interface 101, digital to analog converters 110, an analog mixer 115, and analog spatial enhancement circuitry 7500. Digital to analog converters 110 convert digital audio data received through bus interface 101 into analog signals. Analog mixer 115 mixes signals received from digital to analog converters 110 with an analog signal received from an external source. Analog spatial enhancement circuitry 7500 enhances first and second mixed analog signals output from analog mixer 115.
