Problems solved by technology
[0003] However, due to factors such as computer system reasons and distance factors in the physical environment, there may be a delay when sending out the frequency sweep signal, which will make it difficult to determine the starting point of the truly valid data part in the received frequency sweep data. Furthermore, external signals such as noise in the delay part are also mistakenly tested as part of the frequency sweep signal, which reduces the test accuracy of audio equipment

The invention relates to the technical field of audio, and particularly discloses a testing method and a testing device of audio equipment and computer equipment. The method comprises the following steps: generating an audio test signal, wherein the audio test signal comprises a mark signal arranged at a front end; controlling the audio equipment to output an audio test signal; acquiring an output signal of audio equipment, and generating audio acquisition data; determining effective data in the audio acquisition data according to the mark signal in the audio acquisition data; and determining a test result of the audio equipment based on the valid data. According to the audio equipment testing method, the position of the effective data in the audio collection data can be determined according to the position of the mark signal, then the effective data are obtained, finally, the audio equipment is tested based on the effective data, therefore the effective data can be accurately obtained, and the problem of low test accuracy caused by mixing of external signals such as noise of the delay part is avoided.
Description
technical field [0001] The invention relates to the field of audio technology, in particular to an audio equipment testing method, testing device and computer equipment. Background technique [0002] In the field of audio technology, it is often necessary to test the output performance of audio equipment. Generally, the frequency sweep signal can be played through the audio equipment, and then received, and the received frequency sweep data can be analyzed and processed to determine the output performance of the audio equipment. . [0003] However, due to factors such as computer system reasons and distance factors in the physical environment, there may be a delay when sending out the frequency sweep signal, which will make it difficult to determine the starting point of the truly valid data part in the received frequency sweep data. Furthermore, external signals such as noise in the delay part are also mistakenly tested as part of the frequency sweep signal, which reduces ...
