oscilloscope

I've recently given a presentation about the web-audio-api and web-midi-api. For this talk I wanted to visualize audio waves to see how certain audio-nodes impacted these audio waves. To do this, I created a small javaScript plugin to create an oscilloscope. You can find this plugin on github, and see an example here. To visualize an audio wave, create one, for example with an oscillatorNode. Second create a new oscilloscope instance and connect the oscillator to the oscilloscope. // Create an audio-context var audioContext = new window.AudioContext(), oscillator = audioContext.createOscillator(); oscillator.type = 'sine'; oscillator.frequency.value = 400; oscillator.start(); // Create an…
