Abstract

The invention discloses a multi-audio parameter automatic test method and a test system. The system comprises an audio device to be tested, an audio analyzer, and an automatic test device which is intelecommunication connection with the audio device to be tested and the audio analyzer. When a test is started, the audio analyzer activates corresponding pre-set test items according to the test content of the audio device to be tested, and sends the test items to a processing module for performing analysis processing, wherein the processing module converts the received test items to corresponding test instructions and sends the test instructions to the audio device one by one; and the automatic test device transmits only one test instruction at a time so that the audio device to be tested can be tested once.

Description

technical field [0001] The invention relates to the technical field of audio automatic test methods, in particular to an automatic test method for multiple audio parameters. Background technique [0002] When testing audio indicators, audio analyzers are usually used to test audio equipment (such as microphones, power amplifiers, speakers, etc.) through audio analyzers. The main technical indicators include frequency response characteristics, harmonic distortion, Signal-to-noise ratio, dynamic range, etc., according to the corresponding test parameters of different audio equipment, the audio analyzer is adjusted accordingly. In the actual testing process, some audio equipment has many test items, even as many as dozens of items. Manually operating the audio analyzer to test the audio equipment to be tested according to the test items is cumbersome, time-consuming, and easy. Occurrence of omissions and errors. Contents of the invention [0003] The purpose of the present ...
