APPARATUS AND METHOD FOR PLAYBACK TEST OF AN AUDIO DEVICE

摘要

A system and a method for playback test of an audio device. The method includes the steps of: controlling an audio analyzer ( 3 ) connected to a host computer ( 2 ) to generate analog audio signals at different sampling frequencies, different sampling bit width and different signal amplitude, and controlling the audio analyzer to output the digital audio signals to a client computer ( 5 ) connected to the audio analyzer via an analog signal output interface ( 310 ); receiving the analog audio signals and converting the analog audio signals into first digital audio signals by a first sound card ( 6 ) to be tested inside the client computer; outputting the first digital audio signals to a digital signal input interface ( 311 ) of the audio analyzer; and controlling the audio analyzer to test and analyze the digital signals received at the digital signal input interface, and producing a test result.
