npm install @maybecode/m-recorder
```

## 在线demo
[Demo](https://null_639_5368.gitee.io/mrecorder)

## 示例代码
```
import MRecorder from '@maybecode/m-recorder' 

MRecorder.amrTo(source,{type:'wav'}).then(res=>{
    console.log(res); // { blob, duration, rec}
     audio.src= MRecorder.getAudioSrcByBlob(blob);  // 转换成URL
     audio.play(); // 开始播放
});
```
## 目前实现的功能
```
interface ToConfig {
    type: "wav" | "mp3" | "amr",  // 转换类型
    sampleRate?: number,  // 采样频率
    bitRate?: number //  码率
}
```

```

     * @param source {string | Blob}  http链接或者blob二进制流
     * @param config {ToConfig}  默认值:{  type: "wav",sampleRate: 16000,bitRate: 16,}
     */
    static amrTo(source: string | Blob, config?: ToConfig): Promise<ToReslove>;
