Analysis and test of sound delay on Web Audio under different situations

With the progress and development of science and technology, the sound is applied in different fields. However, people will inevitably encounter the sound delay due to different factors while they are researching on the sound triggered by the event, which has influence on the expected effect to some extent.so It is an imminent thing to propose a reasonable test of sound to delay and analyze the factors causing the sound delay to optimize it. Based on Web Audio, this paper aims to propose a reasonable and effective test method by analyzing the delay generated by audio on different platforms, so as to realize the purpose of automatically testing the sound delay by setting the fixed length. The experimental results show that the delay analyzed by the external stress test is different from that analyzed by the internal stress test under different browsers and different operating systems.
