本文介绍了如何在JavaScript中将语音数据转换为字符串，然后通过C/C++等底层技术进行传输，并详细阐述了接收后如何还原为Blob数据以实现语音播放的整个流程和方案。

过程描述：js中将语音数据转字符串，传输，回来复原，播放

语音数据转字符串：

音频采集器：

function recorder(){
		var onSuccess = function(stream) {

			start.onclick = function(){
				mediaRecorder.start();//begin to record
				//console.log(mediaRecorder.state);//recording
				console.log("开始录音");
				record.style.background = "red";
				stop.disabled = false;
				record.disabled = true;
			}
			stop.onclick = function(){
				mediaRecorder.stop();//stop recording
				//console.log(mediaRecorder.state);//inactive
				console.log("停止录音");
				record.style.background = "";
				record.style.color = "";
				stop.disabled = true;
				record.disabled = false;
			}
			var mediaRecorder = new MediaRecorder(stream);
			mediaRecorder.onstop = function(e) {//when stop happen, do this 
				var audio = document.createElement('audio');
				audio.controls = true;
				var blob = new Blob(chunks, { 'type' : 'audio/ogg; codecs=opus' });//get audio data{type:"text/plain"}
