{{ APIRef("Web Audio API") }}

+ +
+

{{ domxref("AudioContext") }}インターフェースのcreateDelay()メソッドは、入力音声信号を一定時間遅らせる{{domxref("DelayNode")}}を生成します。

+
+ +

構文

+ +
var audioCtx = new AudioContext();
+var synthDelay = audioCtx.createDelay(maxDelayTime);
+ +

引数

+ +
+
maxDelayTime
+
音声信号の最大遅れ時間の秒数。デフォルトは0
+
+ +

戻り値

+ +

{{domxref("DelayNode")}}

+ +

例

+ +

ループする3つの異なる簡単な例を用意しました。create-delayを見てください。(ソースコードも閲覧できます。)ただPlayボタンを押すと、ループはすぐ始まります。スライダーを右に動かしPlayボタンを押すと、待ち時間が挿入され、少し時間が過ぎるまで再生が始まりません。

+ +
var AudioContext = window.AudioContext || window.webkitAudioContext;
+var audioCtx = new AudioContext();
+
+var synthDelay = audioCtx.createDelay(5.0);
+
+  ...
+
+var synthSource;
+
+playSynth.onclick = function() {
+  synthSource = audioCtx.createBufferSource();
+  synthSource.buffer = buffers[2];
+  synthSource.loop = true;
+  synthSource.start();
+  synthSource.connect(synthDelay);
+  synthDelay.connect(destination);
+  this.setAttribute('disabled', 'disabled');
+}
+
+stopSynth.onclick = function() {
+  synthSource.disconnect(synthDelay);
+  synthDelay.disconnect(destination);
+  synthSource.stop();
+  playSynth.removeAttribute('disabled');
+}
+
+...
+
+var delay1;
+rangeSynth.oninput = function() {
+delay1 = rangeSynth.value;
+synthDelay.delayTime.value = delay1;
+}
