Method parameters indicate that startoptions starts recording pause pauses recording resume continues recording stop stops recording onStartcallback recording starts event onPausecallback recording pauses event onStopcallback recording stops event, the file address onFrameRecordedcallback has finished recording files of specified frame size, and the recording shard result data will be called back. If frameSize is set, this event onErrorcallback recording error event and error message will be called back

Start (options) description:

The attribute type is required to indicate whether durationNumber specifies the duration of recording (in ms). If a valid duration is passed, the recording will be stopped automatically when the specified duration is reached, with a maximum value of 600000 (10 minutes). The default value is 60000 (1 minute) sampleRateNumber No sampling rate, valid value 8000/16000/44100numberOfChannelsNumber No recording channels, valid value 1/2encodeBitRateNumber No coding rate. Valid values see below table formatString No Audio format, valid value aac/mp3frameSizeNumber No specify frame size, Unit KB. After frameSize is passed, the content of the recorded file will be called back every time the content of the specified frame size is recorded. If it is not specified, it will not be called back. Only mp3 format is supported.

Among them, the sampling rate and bitrate have certain requirements, and the specific valid values are as follows:

Sampling rate 800016000 ~ 480001102516000 ~ 480001200024000 ~ 640001600024000 ~ 960002205032000 ~ 1280002400032000 ~ 1280003200048000 ~ 1920004410064000 ~ 3200004800064000 ~ 320000

Sample code:

Const recorderManager = wx.getRecorderManager () recorderManager.onStart (() = > {console.log ('recorder start')}) recorderManager.onResume (() = > {console.log (' recorder resume')}) recorderManager.onPause (() = > {console.log ('recorder pause')}) recorderManager.onStop ((res) = > {console.log (' recorder stop', res) const {tempFilePath} = res}) recorderManager.onFrameRecorded ((res) = > {const {frameBuffer} = res console.log ('frameBuffer.byteLength') FrameBuffer.byteLength)}) const options = {duration: 10000, sampleRate: 44100, numberOfChannels: 1, encodeBitRate: 192000, format: 'aac', frameSize: 50} recorderManager.start (options) what does Mini Program mean?
