</script>

引入文件

<script src="./js/recorder.js"></script>

效果

点击按键直接录音

松开按键可直接本次录音

使用方法

var recorder = new Recorder({
    sampleRate: 44100, //采样频率，默认为44100Hz(标准MP3采样率)
    bitRate: 128, //比特率，默认为128kbps(标准MP3质量)
    success: function(){ //成功回调函数
    },
    error: function(msg){ //失败回调函数
    },
    fix: function(msg){ //不支持H5录音回调函数
    }
});

API

//开始录音
recorder.start();
//停止录音
recorder.stop();
//获取MP3编码的Blob格式音频文件
recorder.getBlob(function(blob){ //获取成功回调函数，blob即为音频文件
//  ...
},function(msg){ //获取失败回调函数，msg为错误信息
//  ...
});
