使用JavaScript / HTML5即时生成声音
WebAudioAPI用于控制音频，使您可以选择音频源。您还可以添加效果。创建音频可视化，平移等
示例
您可以尝试运行以下代码片段以生成声音-
// use one context per document. Here we are creating one context for one document. You can create for other documents also var context = new (window.AudioContext || window.webkitAudioContext)(); //振荡器 var os = context.createOscillator(); os.type = 'sine'; // sine is the default. So you can also use square, saw tooth, triangle os.frequency.value = 500; // setting the frequency Hz os.connect(context.destination); // connecting to the destination // starting the振荡器 os.start(); os.stop(context.currentTime + 5); // stop 5 seconds after the current time
