Problems solved by technology

However, in reality, since data packets are transmitted using UDP (User Datagram Protocol), under the wide area network, UDP transmission will have out-of-order and packet loss, and the time for each data packet to reach the receiving end may also vary. Different delays, resulting in the interval between receiving data packets at the receiving end is not

Abstract

The invention discloses an audio play method, and the method comprises the steps: receiving audio data packages, and caching the audio data packages into a first buffering area; detecting the number of audio data packages cached into the first buffering area, and adjusting the decoding speed in real time according to the number of audio data packages; reading the audio data packages from the first buffering area according to the decoding speed, and carrying out decoding play. Correspondingly, the invention also discloses an audio play device. According to the embodiment of the invention, the method and device can improve the smoothness of audio play.

Description

technical field [0001] The invention relates to the field of network technology, in particular to an audio playing method and device. Background technique [0002] Under the wide area network, the ideal audio interactive communication is that the interval between sending data packets at the sending end is equal to the interval between receiving data packets at the receiving end, and the receiving end can directly decode and play the data packets after receiving them. However, in reality, since data packets are transmitted using UDP (User Datagram Protocol), under the wide area network, UDP transmission will have out-of-order and packet loss, and the time for each data packet to reach the receiving end may also vary. Different delays, resulting in the interval at which the receiving end receives data packets is not fixed. If the network becomes better, the interval between receiving data packets at the receiving end becomes smaller, and the receiving end can decode and play ...
