In one embodiment, the recording parameters include a sampling rate, a number of channels, and a size of the storage module.
Wherein the sampling rate can be 44.1kHz or 48kHz, and the number of channels can be single channel or double channels. The audio data collected by recording is firstly placed in the storage module. The storage module is too small, which may cause the initialization of partial recording data to fail, and the storage module is too large, which may affect the reading speed, so the size of the storage module needs to be determined according to the sampling rate and the number of channels.
In an embodiment, the recording parameter further includes a preset recording duration. The preset recording duration is set to control the recording time, and empty recording sections existing due to automatic detection of recording stop are reduced.
In one embodiment, the recording is stopped, comprising: the recording duration reaches the preset recording duration. The method for stopping recording the sound can also be controlled by using preset time length, so that the recording time length is accurately controlled, and the condition that an empty recording section exists due to the fact that the recording stop is detected is avoided. In addition, the user can actively input an instruction to stop recording, and the use experience of the user can be improved conveniently by various control modes.
In one embodiment, the storage module includes an Audio _ Track module, which may be initialized according to the recording parameters.
The Android system can adopt two schemes of MediaPlayer and Audio _ Track to play Audio, generally, mediaPlayer can play more format sound files and is widely applied, but because MediaPlayer can also create Audio _ Track in the frame layer, the response speed is slightly slow, so that the Audio _ Track is often adopted in occasions with high requirements on the real-time response speed of Audio.
In one embodiment, the format of the audio record data includes a PCM format. Audio Track can only play PCM format data streams.
In an embodiment, before the step of configuring the recording parameters, the method further includes:
applying for recording authority and recording data read-write authority.
