JSXGraph can be used together with the excellent JavaScript audio library gibberish.
The underlying JavaScript code
Additionally embed gibberish.js:
<script type="text/javascript" src="https://www.charlie-roberts.com/gibberish/build/gibberish.js"></script>
Gibberish.init();
Gibberish.Time.export();
Gibberish.Binops.export();
var board = JXG.JSXGraph.initBoard('jxgbox', {boundingbox:[-1,10,10,-10], axis:false});
var sinewave = new Gibberish.Sine( 440, .25 ).connect();
var slide = board.create('slider', [[2, 8], [8, 8], [100, 440, 1000]]);
var sinecurve = board.create('functiongraph', [function(x) { return 5 * Math.sin((sinewave.frequency / 200.0) * 2* Math.PI * x); }]);
board.on('update', function() {
sinewave.frequency = slide.Value();
});
