Multi-channel test system and method

Abstract

The invention discloses a multi-channel test system and method. The multi-channel test system comprises a sound transmission module, a switching module, an audio output terminal, an audio input terminal and an audio playing module, wherein the switching module connects a target audio output terminal and a target audio input terminal to a channel connection bus according to a channel switching signal; the sound transmission module converts sound into an audio signal and sends the audio signal to the target audio output terminal through the channel connection bus; the target audio output terminal transmits the audio signal to the target input channel; and the target audio input terminal receives an audio output signal fed back by the target output channel and sends the audio output signal to the audio playing module through the channel connection bus, so the audio playing module plays the audio output signal, and a target input channel and a target output channel are tested according to the playing effect. Signal transmission is carried out by using the channel connection bus, and channels are switched by using the switching module, so labor waste caused by manual plugging and unplugging is reduced, and multi-channel testing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of signal control, in particular to a multi-channel testing system and method. Background technique [0002] In the audio processor equipment, there are multiple channel analog signals, these analog signals include input signal and output signal, the effect of the input signal and output signal is an extremely important performance index of the audio processor equipment, which is crucial to guarantee the production process one of the important factors. [0003] The current various multi-channel analog acquisition, sampling of output devices, and effect testing of output channels (hereinafter referred to as "tested channels") are mainly through manually connecting the microphone to the input channel of the device to be tested according to each channel to be tested. Connect the output channel to be tested to the active speaker, operate the computer and open the relevant control software to supply phantom powe...
