使用 JavaScript/ HTML5 实时生成声音
网络音频 API 用于控制音频,允许您选择音频源。您还可以添加效果;创建音频可视化效果、声像定位等等。
示例
您可以尝试运行以下代码段来生成声音 −
// 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)(); // oscillator 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 oscillator os.start(); os.stop(context.currentTime + 5); // stop 5 seconds after the current time
