AI Technical Summary

Problems solved by technology

After ios4.3, it no longer supports playback of audio in amr format, but the audio file in wav format is too large to be convenient for network transmission, and amr has a relatively large compression ratio. Although the quality is average compared to other compression formats, the audio file is small. It is good for transmission. In addition, the effect of data vocals and calls in amr format is still very good, so it is mainly used for audio of mobile devices
At present, similar applications mainly use third-party libraries or implement decoding through the server side. The former has poor scalability, and the latter will undoubtedly increase the workload of the server and affect the response speed.

Embodiment Construction

[0015] Such as figure 1 As shown, this embodiment is a mobile phone cross-platform language transmission decoding method, which solves the task that the client of the ios platform receives the amr format audio file from the Andorid client and plays it back.

[0016] The ios client receives the amr format audio file of the Andorid client, and converts the amr format audio file into an audio file in the wav format, and then replays the wav format audio file through the player on the ios platform, including the following steps:

[0017] A. Read the standard frame in the amr format audio file, and calculate the size of the standard frame according to the standard frame header;

[0018] B. Create and initialize an audio file in wave format;

[0019] C. Read other frames in the amr format audio file;

[0020] D. Judging whether these frames are consistent with the standard frame size, if not, it is a bad frame, and then discarded, otherwise turn to step E;

[0021] E, read the au...

Abstract

The invention provides a cross-platform speech transmission / decoding method for mobile phones, which comprises the following steps that: an ios client receives amr-format audio files of an Andorid client, converts the amr-format audio files into wav-format audio files, and then, replays the wav-format audio files on an ios platform through a player. According to the invention, the ios client receives amr-format audio data of the Andorid client, then calls a decoding method, and returns wav-format audio data, thereby realizing the audio transmission between the ios client and Andriod client.

Description

technical field [0001] The present invention relates to the field of mobile phone platform file formats, in particular to the data decoding problem of voice transmission between Apple's ios platform and the Andriod platform, specifically a file in the amr format converted into a wav format file on the ios platform, for use Player replay on ios platform. Background technique [0002] With the development of the mobile Internet, the distance between people is getting closer and closer, and the way of communication is not limited to text and pictures, but the need to transmit information directly through sound is becoming more and more common. At present, smart phones are long-term occupied by the two major platforms of ios and Andriod. Apple iOS is an operating system for handheld devices developed by Apple Inc. Like Apple's Mac OS X operating system, iOS has already occupied 30% of the global smartphone system market share and 43% in the United States. Android is a Linux-ba...
