Play Sound

There are a number of ways to play sound via TouchControl.  A couple of the easiest are:

1. Add an audio file (.mp3, .wav, etc.) to the "html" folder under your TouchControl server data directory.  Then create a Script button with the following Javascript:

new Audio(‘html/my_audio_file.mp3’).play();

2. Create a script button with the following script:

var audioCtx = new window.webkitAudioContext;

function beep(duration, frequency, volume, type, callback) {

    var oscillator = audioCtx.createOscillator();

    var gainNode = audioCtx.createGain();

    oscillator.connect(gainNode);

    gainNode.connect(audioCtx.destination);

    if (volume){gainNode.gain.value = volume;};

    if (frequency){oscillator.frequency.value = frequency;}

    if (type){oscillator.type = type;}

    if (callback){oscillator.onended = callback;}

    oscillator.start();

    setTimeout(function(){oscillator.stop()}, (duration ? duration : 500));

};

beep();

Make sure you don’t have your device muted!
