Question

無法通過createAnalyser處理音頻數據。當遠程音頻流連接到分析儀時，聲音變爲靜音或不播放。難道這曾經打算拿不動，那種沮喪

Answer 1

你可以看到遠程音createAnalyser這裏一個完整的例子： http://git.io/vegtp

var audioData = ajaxRequest.response; 
var audioCtx = new (window.AudioContext)(); 
audioCtx.decodeAudioData(audioData ... 
var analyser = audioCtx.createAnalyser(); 

隨着流來源：http://git.io/vegmk

var audioCtx = new AudioContext(); 
audioCtx.createMediaStreamSource(stream); 
var analyser = audioCtx.createAnalyser();
