+<p>Метод <code>createPanner()</code> интерфейса {{ domxref("AudioContext") }} применяется для создания нового {{domxref("PannerNode")}}, который используется для размещения аудиопотока в виртуальном 3D пространстве.</p>
+</div>
+
+<p>The panner node is spatialized in relation to the AudioContext's {{domxref("AudioListener") }} (defined by the {{domxref("AudioContext.listener") }} attribute), which represents the position and orientation of the person listening to the audio.</p>

+<div class="note_trans">
+<div>Ниже можно увидеть пример использования {{domxref("AudioListener")}}, {{domxref("PannerNode")}} и метода <code>createPanner()</code> для управления пространством объемного звука. Обычно определяется положение в трехмерном пространстве, изначально занимаемое слушателем (listener) и источником звука (panner), а затем, при использовании приложения, обновляется позиция одного из них или обоих. Например, вы можете перемещать персонажа внутри игрового мира, и желательно чтобы передача звука изменялась реалистично, по мере приближения или отдаления персонажа относительно источника звука, вроде стереопроигрывателя. В этом примере можно видеть, что все это управляется функциями <code>moveRight()</code>, <code>moveLeft()</code>, и т.п., которые устанавливают новые значения для положения паннера через функцию <code>PositionPanner()</code>.</div>

+<p>{{ APIRef("Web Audio API") }}</p>
+
+<div>
+<p>The <code>decodeAudioData()</code> method of the {{ domxref("AudioContext") }} Interface is used to asynchronously decode audio file data contained in an {{domxref("ArrayBuffer")}}. In this case the <code>ArrayBuffer</code> is usually loaded from an {{domxref("XMLHttpRequest")}}'s <code>response</code> attribute after setting the <code>responseType</code> to <code>arraybuffer</code>. The decoded AudioBuffer is resampled to the AudioContext's sampling rate, then passed to a callback or promise.</p>
+</div>
+
+<p>This is the preferred method of creating an audio source for Web Audio API from an audio track.</p>
+
+<h2 id="Syntax">Syntax</h2>
+
+<p>Older callback syntax:</p>
+
+<pre class="syntaxbox">audioCtx.decodeAudioData(audioData, function(decodedData) {
+  // use the dec​oded data here
+});</pre>
+
+<p>Newer promise-based syntax:</p>
+
+<pre class="syntaxbox">audioCtx.decodeAudioData(audioData).then(function(decodedData) {
+  // use the decoded data here
+});</pre>
+
+<h2 id="Example">Example</h2>
+
+<p>In this section we will first cover the older callback-based system and then the newer promise-based syntax.</p>
+
+<h3 id="Older_callback_syntax">Older callback syntax</h3>
+
+<p>In this example, the <code>getData()</code> function uses XHR to load an audio track, setting the <code>responseType</code> of the request to <code>arraybuffer</code> so that it returns an array buffer as its <code>response</code> that we then store in the <code>audioData</code> variable . We then pass this buffer into a <code>decodeAudioData()</code> function; the success callback takes the successfully decoded PCM data, puts it into an {{ domxref("AudioBufferSourceNode") }} created using {{ domxref("AudioContext.createBufferSource()") }}, connects the source to the {{domxref("AudioContext.destination") }} and sets it to loop.</p>
+
+<p>The buttons in the example simply run <code>getData()</code> to load the track and start it playing, and stop it playing, respectively. When the <code>stop()</code> method is called on the source, the source is cleared out.</p>
+
+<div class="note">
