Abstract
With the application of audio in various fields, the reliability of transmission and delay have been improved to a certain extent. However, there is no quick and effective method to test the delay of audio transmission nowadays. Therefore, it is an urgent matter to propose a reasonable method to test the audio delay. This paper takes web audio as research object, proposing a method of automatically testing web audio delay based on NTP, on the basis of which the delay of web audio is tested from two perspectives namely local delay and network delay. The experimental results show that the auto-delay testing method for web audio proposed in this paper is more flexible and efficient than other testing methods, especially for web audio testing.
