HarmonyOS 使用AudioCapturer录音后音频转wav或者mp3格式？

Question

目前才有下面代码的方式录音频，并生成了pcm文件，但是无法直接播放。使用了在线转换后可正常播放，api文档中未找到转码的代码。希望可以提供一个示例（不要C/C++的）。

import { audio } from '@kit.AudioKit';

let audioStreamInfo: audio.AudioStreamInfo = {
  samplingRate: audio.AudioSamplingRate.SAMPLE_RATE_44100,
  channels: audio.AudioChannel.CHANNEL_2,
  sampleFormat: audio.AudioSampleFormat.SAMPLE_FORMAT_S16LE,
  encodingType: audio.AudioEncodingType.ENCODING_TYPE_RAW
}
let audioCapturerInfo: audio.AudioCapturerInfo = {
  source: audio.SourceType.SOURCE_TYPE_MIC,
  capturerFlags: 0
}
let audioCapturerOptions: audio.AudioCapturerOptions = {
  streamInfo: audioStreamInfo,
  capturerInfo: audioCapturerInfo
}
audio.createAudioCapturer(audioCapturerOptions, (err, data) => {
  if (err) {
    console.error(`AudioCapturer Created : Error: ${err}`);
  } else {
    console.info('AudioCapturer Created : Success : SUCCESS');
    let audioCapturer = data;
  }
});

可以参考音频编码文档：https://developer.huawei.com/consumer/cn/doc/harmonyos-guides-V5/audio-encoding-V5
