Abstract

See full text

An audio processing apparatus having an echo canceling mechanism is provided. An audio transmission circuit receives an input digital audio signal from an external device. A DAC circuit performs conversion according to the input digital audio signal to generate an output analog audio signal to an external display device for power amplification and playback. An ADC circuit performs analog-to-digital conversion on an amplified signal generated by a power amplification circuit and a received audio signal generated by an audio receiving device to generate an amplified digital signal and a received digital audio signal. A processor implements an echo canceling algorithm to perform echo cancellation according to the amplified digital signal and the received digital audio signal to generate an output digital audio signal to be transmitted to the external device through the audio transmission circuit.
