Embodiment Construction

[0017] The technical solution of the present invention will be described below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, the present invention provides a kind of audio file storage method, may comprise the following steps:

[0019] S1, when the playback device plays the audio data sent by the terminal storing the audio file, synchronously performs PCM (Pulse Coded Modulation, Pulse Code Modulation) sampling on the audio data to obtain PCM audio data, and buffers the PCM audio data ;

[0020] Wherein, the playback device is set separately from the terminal, and the playback device and the terminal can perform data transmission. In one embodiment, the playback device may be an audio playback device such as a Bluetooth player, and the terminal may be an intelligent terminal such as a mobile phone or a tablet computer. Generally speaking, smart terminals such as mobile phones and tablet computers can support the Bluetooth protocol, and t...

Abstract

The present invention relates to an audio frequency file storage method and system. The method comprises: when a play device plays the audio frequency data sent by a terminal storing the audio frequency file, performing PCM sampling of the audio frequency data at the same time, obtaining the PCM audio frequency data, and performing cache of the PCM audio frequency data; when the play process of the audio frequency data reaches a preset play terminal point, performing compression of the cached PCM audio frequency data according to the setting audio frequency file format; and storing the compressed PCM audio frequency data onto the storage medium of the play device. The audio frequency file storage method and system are wide in usage range and high in usage flexibility, do not influence the audio frequency file play, and can store the audio frequency file while playing the audio frequency file, and are high in efficiency.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to an audio file storage method and system. Background technique [0002] When playing audio files, there is a scenario where the storage terminal for storing audio files and the playback terminal for playing audio files are two separate terminals. The files are stored in the mobile phone, and the playback device is set on the vehicle side. In this case, the playback terminal only performs the playback function, but does not store the audio file. However, in practical applications, the user may need to store the audio file in the playback terminal so as to play the audio file at any time. [0003] In traditional technology, if the audio file needs to be stored in the playback terminal, it is usually necessary to install specific software on both the playback terminal and the storage terminal. During transmission, the software transfers the audio file from The storage ter...
