A kind of sound effect test method of car audio system

Abstract

The invention provides a sound effect test method of a vehicle-mounted sound system. The method comprises the following steps: obtaining original audio, obtaining audio played by the vehicle-mounted sound system, intercepting the audio within the same time period, performing eq sound effect superimposition on the original audio, and comparing the played audio with the original audio subjected to the eq sound effect superimposition to obtain a comparison result at last. If noise detection is performed on the playing system, the eq sound effect superimposition is not performed on the original audio, and no eq sound effect is added when the original audio is played. As the method is used for testing the sound system, whether the noise exceeds the standard and whether the eq sound effect meetsthe expected standard can not only be accurate detected, the test efficiency is also improved, the test cost is reduced, and the sound quality of the playing system can be ensured.

Description

technical field [0001] The invention relates to the field of sound effect testing of audio playback systems, in particular to a sound effect testing method of a vehicle audio system. Background technique [0002] Eq sound effect is to modify the overtone level of each frequency in the sound, and optimize it for a certain type of music to enhance people's music experience, usually including normal, rock, pop, dance, classical, soft, jazz, metal, heavy Bass and custom. At present, all kinds of music players have EQ sound adjustment, and the car infotainment system is no exception. [0003] In the development process of the vehicle infotainment system, testers need to test the audio output; test whether the audio is mixed with noise during the output process, and confirm whether the output audio in each eq sound effect mode meets the expected standard. At present, testers usually use the human ear to distinguish, and the human ear distinguishes defects with individual differe...

AI Technical Summary

Problems solved by technology

At present, testers usually use the human ear to distinguish, and the human ear distinguishes defects with individual differences. The hearing sensitivity of each tester is different, and some slight noises may not be recognized by the human ear; and the human ear cannot be accurate. Judging whether the playback system meets the standard in each eq sound effect mode; this requires multiple testers to cross-test, not only the test efficiency is low, but also the cost is high; the sound quality of the playback system cannot be guaranteed
