This synth piano is written solely using HTML, JS, and CSS. It contains a small handful of synths with configurable decays, a looper, demo mode, visual mode, and a variety of colors. View controls by hitting the top-right button on the piano.
[…] By dividing up the sound data for each song and computing its appearance in realtime, the resulting visualisation gives you an understanding of the unique anatomy of this particular mashup.
The entire piece is composed from the latest HTML5 and CSS3 technology (canvas, audio, transforms & transitions) so you’ll need a newer browser to view it in. I recommend Chrome because it pulls off the best performance with my mangled code. All of the waveform and spectrum visualisation is performed in realtime, so your browser is rendering a music video on the fly!
Hopefully it gives you a new insight into the artform of the mashup, otherwise you can just stare at the pretty shapes.
