The audio file being written is divided into a plurality of file segments, and the plurality of file segments are separately read. FIG. 2 is a flowchart of a method for recording synchronization provided by an embodiment of the present disclosure. Referring to FIG. 2, the embodiment specifically includes:

200, the terminal device starts the recording function, and performs steps 201 and 204 respectively;

When the recording function is started, the terminal device performs recording initialization, and starts collecting sound through the microphone to obtain an audio data stream. At this time, an upload request is sent to the server for the data synchronization service, and the upload request is used to request real-time uploading of the currently recorded An audio file, and requesting the server to assign a file identifier to the audio file being recorded.

201. During the recording process, the terminal device acquires an audio data stream.

After starting the recording function and initializing the recording, you need to check whether the user wants to continue recording. If yes, continue to obtain the audio stream acquisition. If not, exit the recording function.

202. The obtained audio data stream is encoded according to a preset encoding format, and the terminal device writes the encoded data into an audio file.

Specifically, each time the audio data stream is acquired, the terminal device performs MP3 format encoding on the acquired audio data stream, and writes the encoded generated data into the audio file.

When acquiring the audio data stream, the audio data stream is encoded in the MP3 format, and the collected PCM data is encoded into an MP3 format audio file for storage, and the process is repeated to continuously convert the external audio information. Into a continuous MP3 audio file.

203. When the recording process ends, the terminal device supplements the file end of the obtained audio file, and outputs the supplemented The audio file ends.

It should be noted that the encoding process of the MP3 format is a process of continuously acquiring an audio data stream and continuously encoding, and continuously repeating the process to convert the external audio information into an MP3 audio file including continuous frames. Because the MP3 storage format has high audio compression rate and low distortion, the MP3 encoding format can greatly facilitate the user's storage and use of audio. And because of the particularity of the MP3 encoding format, the encoding is performed one frame at a time, so during the audio recording process, even if the recording pauses, the previously saved frame is not lost, and the device will not be powered down due to pause or interruption of the recording. If you lose the previously saved frame, it has higher stability than recording in formats such as amr or 3gpp.

204. The terminal device sends an upload request to the server.

Preferably, when the terminal device is detected to access the network, the uploading process is started. Or, when it is detected that the terminal device is not connected to the network, the user is prompted to open the network connection for recording synchronization, and when the user is detected to open the network connection, the uploading process is started.

The upload request is used to request that the currently recorded audio file be uploaded in real time, and the server is requested to assign a file identifier to the audio file being recorded. The server assigns a file identifier to the audio file of this recording according to the upload request of the terminal device.

In the embodiment of the present disclosure, when receiving the uploading request of the terminal device, the server may randomly assign a file identifier to the audio file of the recording, and the file identifier is used by the terminal device to carry the data when uploading, so that the server identifies the file according to the file. Correspondly save the received data.

205. After the terminal device obtains the file identifier allocated by the server, set the zero byte position of the file to the file read position.

The file read position is used to identify the location of the data that the current audio file has read and uploaded in the audio file.

Preferably, when the terminal device starts recording and reads data for the first time, the file read position can be initially set, that is, the zero byte position of the audio file is set to the file read position.

206. The terminal device reads the data from the audio file being written by using the file read position as the starting point of the current reading;

The size of the data that is read each time may be a preset value, which may be set by the technician at the time of development, and may be adjusted by the user according to the requirement, which is not limited by the embodiment of the disclosure.

207. The terminal device uploads, according to the file identifier allocated by the server, the data read each time to the end of the file of the audio file corresponding to the file identifier saved by the server;

When the terminal device performs data uploading, the uploaded data carries the file identifier allocated by the server. When the server receives the data carrying the file identifier, the file determines the audio file corresponding to the file identifier according to the file identifier, and the received audio file is received. The data is saved to the end of the file of the audio file corresponding to the file identifier, which ensures the continuity of the audio data saved on the server side.

It should be noted that if the data upload fails, you need to continue to try uploading until the upload is successful. 208. The terminal device updates the read position of the file according to the location of the last read data in the audio file.

For example, if the last data read is 1024 bytes of the audio file, then 1024 bytes are updated to the file read position, and at the time of this reading, the 1024 byte position is used for the current reading. At the beginning, the data after 1024 bytes in the audio file is read.

209. Before the data is read, the terminal device determines whether the currently updated read position is the end of the file of the audio file, and if yes, step 210 is performed; if not, step 206 is performed according to the updated file read position.

Preferably, since at least one data reading and uploading is required during the recording process, in order to ensure that the reading and uploading of the data is not interrupted, it is determined whether the read position of the current file has been read before each reading. Read the end of the file of the audio file to know if there is still data to upload. When the file has been read at the end of the file of the audio file, the data upload can be ended. When the file has been read at the end of the file of the audio file, Need to continue to read data from the audio file and upload.

Specifically, before the data is read, the terminal device determines whether the currently updated read position is the end of the file of the audio file, and if so, it considers that the recording ends and ends the data upload, and if not, the recording is not yet finished. According to the updated read position of the file, the read position in the audio file being written is the starting point of the current reading, and the data is continuously read from the audio file being written.

In addition, the embodiment of the present disclosure is described by taking the data in the audio file and uploading the data as an example. In another implementation manner provided by the embodiment of the present disclosure, the audio file being written may also be divided into multiple a file segment, the plurality of file segments are separately read, since the encoding of the audio file is performed one frame at a time, the audio file may also be segmented during the data reading and uploading process. Each file segment is a complete audio file. When the terminal device reads and uploads multiple file segments to the server separately, the server sequentially saves multiple file segments, and can also complete the synchronization of the recording to achieve the recording. The purpose of real-time backup of audio files.

210. Determine whether the recording is stopped. If yes, end the data upload; if no, go to step 206. It should be noted that if the upload speed is faster than the recording speed, it may be uploaded to the end of the file, but the recording is still adding new recording content to the end of the file, so it is necessary to judge whether to judge the recording after the end of the file. Whether to stop, if the recording has stopped, end this upload task.
