Add a link to WebAudioFontPlayer.js and the instrument file. Invoke queueWaveTable.
Minimal HTML page
``html`
See live example.
Use queueWaveTable to play single note. Use queueChord, queueSnap, queueStrumDown, queueStrumUp to play chords. See live example for strumming.
Use time for notes to define sequence. See live example of sequencer.
Use the startLoad and waitLoad functions.
`javascript`
var instr=null;
var AudioContextFunc = window.AudioContext || window.webkitAudioContext;
var audioContext = new AudioContextFunc();
var player=new WebAudioFontPlayer();
function changeInstrument(path,name){
player.loader.startLoad(audioContext, path, name);
player.loader.waitLoad(function () {
instr=window[name];
});
}
changeInstrument('https://surikov.github.io/webaudiofontdata/sound/0290_Aspirin_sf2_file.js','_tone_0290_Aspirin_sf2_file');
All loaded instruments are cached in memory.
See live example
Use WebAudioFontChannel to create a chain of 10-band equalizers.
Use WebAudioFontReverberator to add echo.
See live example
See tutorial
WebAudioFont doesn't require installation. It hosts all code and instruments at GitHub Pages.

WebAudioFont uses Web Audio API to play instruments.
Synthesizer uses wavetables to play sound.
Instruments came from free soundfonts:
- GeneralUserGS.sf2 license
- FluidR3.sf2 license
#### How to use catalog of sounds:
- open index page
- find an instrument
- copy the name of the file to include the instrument data
- copy the name of the variable to refer to the instrument
- add this info to a page
Use drumInfo and instrumentInfo in realtime. See live example.
WebAudioFontPlayer has the function queueWaveTable(audioContext, target, preset, when, pitch, duration, volume, slides)
Parameters:
- audioContext - AudioContext
- target - a node to connect to, for example audioContext.destination
- preset - variable with the instrument preset
- when - when to play, audioContext.currentTime or 0 to play now, audioContext.currentTime + 3 to play after 3 seconds
- pitch - note pitch from 0 to 127, for example 2+12*4 to play D of fourth octave (use MIDI key for drums)
- duration - note duration in seconds, for example 4 to play 4 seconds
- volume - 0.0 <=1.0 volume (0 is 'no value', 'no value' is 1)
- slides - array of pitch bends
The function queueWaveTable returns an envelope object. You can use this object to cancel a sound or to access AudioBufferSourceNode.
#### Strumming
Use queueChord, queueStrumUp, queueStrumDown, queueSnap for chords. See live example.
Feel free to ask for any kind of help at project issues.
The catalog consists of a full set of MIDI standards. Each instrument has 5-10 sound variations from different soundfonts.
