Embodiment Construction

[0029] The above-mentioned features and advantages of the present invention can be better understood after reading the detailed description of the embodiments of the present disclosure in conjunction with the following drawings. In the drawings, components are not necessarily drawn to scale, and components with similar related properties or characteristics may have the same or similar reference numerals.

[0030] figure 1 The overall flow of the cross-platform audio transmission method of the present invention is shown. See figure 1 , firstly, record the voice file on the system platform of the sending terminal. On the Android platform, the format of the recorded voice file is AMR format; on the IOS platform, the recorded voice file is in WAV, CAF, MP3 and other formats (the WAV format is used as an example below); on the Windows platform, the recorded voice file Formats of audio files such as WAV, CAF, MP3 (hereinafter, the WAV format is used as an example for illustration...

Abstract

The present invention discloses a cross-platform audio frequency transmission method. The method comprises: realizing cross-platform high-efficiency transmission of an audio frequency file in a plurality of terminal platform, and providing an audio frequency file buffer memory method on the terminals. The technical scheme of the invention comprises: conversion of the coding formats of the audio file recorded by a terminal platform and a preset coding format is employed to realize cross-platform transmission, and MD5 value is calculated through URL to play the audio file stored in local in advance. After the capacity of the local storage is full, the longest unused voice file is deleted according to the LRU strategy. Compared to the prior art, the high-efficiency transmission of the audio file among multiple platforms such as IOS, Android, Window and the like can be realized, and play audio can perform automatic offline buffer so as to allow users to greatly save the network data flow.

Description

technical field [0001] The invention relates to a transmission method on the Internet, in particular to a cross-platform audio transmission method in instant messaging. Background technique [0002] With the rapid development of the mobile Internet, instant messaging tools have gradually become familiar to people. The way of communication is not limited to text and pictures, and it is more and more common to transmit information directly by voice. [0003] In current mobile applications, the AMR audio format is generally used as the voice transmission format. The Apple platform IOS4 no longer supports the AMR audio format, and only supports WAV, CAF, MP3 and other relatively large audio formats. However, these voice formats are not convenient for network transmission, and relatively expensive data traffic. [0004] The current mobile network does not cover every corner, and it is impossible for the user terminal to play the previously played voice offline at any time. The ...
