const recorderManager = wx.getRecorderManager() recorderManager.onStart(() => { console.log('recorder start') }) 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) 官方文档的示例代码就不行，安卓ios可以，pc不行

请教一个问题，在做微信录音的时候想尝试下onFrameRecorded边录边分析的功能，可是demo代码一直没有触发onFrameRecorded回调。代码就是copy官方的实例，一点改动都没有      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) => {             const { tempFilePath } = res             t.uploadAudio(tempFilePath)         })         recorderManager.onFrameRecorded((res) => {             const { frameBuffer } = res             alert(1)             console.log('frameBuffer.byteLength', frameBuffer.byteLength)         })                  const options = {             duration: 5000,             sampleRate: 44100,             numberOfChannels: 1,             encodeBitRate: 192000,             format: 'mp3',             frameSize: 50         }         recorderManager.start(options)                  不管是用开发工具，还是用手机测试，都没有相应的反应。很是惆怅啊。大家可以指点下吗？
