Problems solved by technology

[0016] It can be seen that in the process of testing audio equipment, specific parameter values ​​must be manually set for each test parameter, and each test audio file must be manually compared. Therefore, the current implementation of audio equipment testing method, there is a problem of heavy testing workload for testing audio equipment

Embodiment Construction

[0058] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0059] The technical solution of the present invention is: set at least one test mode; control the audio equipment under test to traverse each test mode, process the input audio signal of the audio equipment under test, and obtain the output audio signal under each test mode; The input audio signal and the output audio signal in each test mode are compared in waveform; according to the waveform comparison result, the test result of the audio device under test in each test mode is obtained.

[0060] FIG. 2 is a schematic structural diagram of the system of the present invention, the system includes: a control module 210, an audio device under test 220, and a comparison module 230;

[0061] The control module 210 sets at least one test mode...

Abstract

A method for testing audio device includes setting at least one test mode according to test mode supported by tested audio device, controlling tested audio device to make ergodic on each test mode, processing input audio signal of tested audio device to obtain output audio signal under each test mode, carrying out waveform comparison on input and output audio signals under each test mode and obtaining test result of tested audio device at each test mode according to waveform comparison result. The system and audio device both being used for realizing said method is also disclosed.

Description

technical field [0001] The invention relates to the field of audio, in particular to a method, system and audio equipment for realizing audio equipment testing. Background technique [0002] Audio equipment is a general term for audio input and output equipment, which can include a variety of product types, such as power amplifiers, players, recorders, microphones, sound cards in personal computers, headphones, etc. Before these audio equipment is officially put into the market, it usually requires Test the sound quality, sound effects, etc. For example, the listening test of MP3 (MPEG Audio Layer 3) players is to manually judge whether the sound played by the MP3 player is distorted, whether there are noises, etc. test. [0003] Because audio equipment can support multiple test parameters, and for each test parameter, it can be set to one or more specific parameter values, therefore, when testing audio equipment, it is necessary to specify the specific parameter values ​​o...
