可以，关掉自动解码，在transform里面手动调用Recorder.AMR.decode进行解码成pcm，参考Recorder.amr2wav

[machine-w]

testTransform=function(arrayBuffer,sampleRate,True,False){
var reader=new FileReader();
reader.onload=function(){
var amr=new Uint8Array(reader.result);
Recorder.AMR.decode(arrayBuffer,function(pcm){
Recorder({type:"pcm"}).mock(pcm,sampleRate).stop(function(wavBlob,duration){
True(wavBlob,duration);
},False);
},False);
};
reader.readAsArrayBuffer(new Blob([arrayBuffer]));
};
var socket = io('http://127.0.0.1:8085', {transports: ['websocket']});
socket.binaryType = 'arraybuffer';
stream=Recorder.BufferStreamPlayer({
decode:false, //传输过来的不是pcm就需要开启解码
play:true, //要播放声音，设为false不播放，只提供MediaStream
realtime:true,
transform:function(pcm,sampleRate,True,False){
console.log(pcm);
testTransform(pcm,sampleRate,function(pcm,sampleRate){
// True(pcm,sampleRate);
testSampleRate=sampleRate;
// testAllPcm.push(pcm);//另存一份 结束时转成一个完整音频 对比接收到的数据音质
},False);
}
});

报错：n.subarray is not a function at Object.decode (beta-amr.js:6:777)
