+
+ This uses the [link:https://developer.mozilla.org/en-US/docs/Web/API/Web_Audio_API Web Audio API].

+ <code>
+ //Create an AudioListener and add it to the camera

+ <h2>Constructor</h2>
+
+
+ <h3>[name]( audio, [link:https://developer.mozilla.org/en-US/docs/Web/API/AnalyserNode/fftSize fftSize] )</h3>
+ <div>
+ Create a new [page:AudioAnalyser AudioAnalyser].
+ </div>
+
+
+ <h2>Properties</h2>
+
+ <h3>[property:AnalyserNode analyser]</h3>
+ <div>An [link:https://developer.mozilla.org/en-US/docs/Web/API/AnalyserNode AnalyserNode] used to analyze audio.</div>
+
+ <h3>[property:Integer fftSize]</h3>
+ <div>
+ A non-zero power of two up to 2048, representing the size of the FFT (Fast Fourier Transform) to be used to determine the frequency domain.<br />
+ See [link:https://developer.mozilla.org/en-US/docs/Web/API/AnalyserNode/fftSize this page] for details.
+ </div>
+
+ <h3>[property:Uint8Array data]</h3>
+ <div>
+ A Uint8Array with size determined by [link:https://developer.mozilla.org/en-US/docs/Web/API/AnalyserNode/frequencyBinCount analyser.frequencyBinCount]
+ used to hold analysis data.
+ </div>
+
+
+ <h2>Methods</h2>
+
+
+ <h3>[method:Uint8Array getFrequencyData]()</h3>
+ <div>
+ Uses the Web Audio's [link:https://developer.mozilla.org/en-US/docs/Web/API/AnalyserNode/getByteFrequencyData getByteFrequencyData] method.
+ See that page.
+ </div>
+
+ <h3>[method:Number getAverageFrequency]()</h3>
+ <div>
+ Get the average of the frequencies returned by the [page:AudioAnalyser.getFrequencyData getFrequencyData] method.
+ </div>
