TONE.JS!
- A Web Audio framework for web-based applications
- Both for musicians and audio programmers (no execuses!)
- higher-level constructs (e.g. pre-built Synth, Sampler, Sequencer)
- pre-built instruments and effects
- built-in Transport to handle timing (e.g. schedule future events)
- MIDI data support
const audioC = new window.AudioContext
const osc= audioC.createOscillator()
const gainN = audioContext.createGain()
osc.type = 'sine'
osc.frequency.setValueAtTime(261.63, audioC.currentTime)
osc.connect(gainN).connect(audioC.destination);
osc.start()
gainN.gain.setValueAtTime(1, audioC.currentTime)
gainN.gain.exponentialRampToValueAtTime(0.001, audioC.currentTime + 1)
osc.stop(audioContext.currentTime + 1)
const synth = new Tone.Synth().toDestination()
synth.triggerAttackRelease("C4", "8n")
