Speex Codec in Javascript

Speex Codec in Javascript. Ported speex-1.2.0RC using emscripten tool.

• Both encoder and decoder (see demo)

• aurora.js integration (see demo)

(Microphone loopback is only working in Firefox.)

播放网络 数据：ogg 转 wav

 var samples, sampleRate;
 var xhr = new XMLHttpRequest();
 xhr.open("get", "https://image-public.touhaozhubo.com/video2017072415145513096056530311.spx", true);
 // 下载 数据
 xhr.responseType = "blob";// 以二进制下载 数据
 xhr.onreadystatechange = function() {
 if (xhr.readyState == 4 && xhr.status == 200) {
   console.log(xhr.response);
   var blob =  xhr.response;
   var reader = new FileReader();// 用 FileReader 读取 blob 数据
   reader.addEventListener("loadend", function() {
   var data = reader.result;
   // var data =  xhr.response,
   var  ret, header;
   ret = Speex.decodeFile(data);
   samples = ret[0];
   header = ret[1];
   sampleRate = header.rate;
   addDownloadLink("test"+".wav", "#file_ogg",samples, "audio/wav");
   Speex.util.play(samples, sampleRate);
  });
 reader.readAsBinaryString(blob); // 将文件读取为二进制编码
 }
 };
 xhr.send(null);
