    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

I don't even have my sound on right now, I'll have to come back to it later. Most unique dweet I've seen in a while though!

Play freebird
u/pangolin

I've been trying to get something that would play different notes, but I can't get it small enough. The next step would clearly be freebird.
u/recursive

There's a separate audio synthesis api that might work. It's kind of wordy though
u/mxfh

;new Audio("data:audio/wav;base64,UklGRsYAAABXQVZFZm10IBAAAAABAAEAQB8AAIA+AAACABAAZGF0YaIZAAA"+c.toDataURL("image/bmp").substr(22,4000)).play()
u/mxfh

have no idea how to tweak the wav header to align samples with imagedata and where the bmp header ends, but just past this to the end of any dweet
u/pangolin

There isn't much that changes in the header info: http://soundfile.sapp.org/doc/WaveFormat/
u/mxfh

ok here's your header tweak tool: http://codepen.io/mxfh/pen/mWLMrJ
