The music slowly changes over time and will not stop on its own. This is a new idea combining the oscillator setup with byte beat music to allow for enough space to write graphics code!
u/KilledByAPixel

uncompressed... t?t*=60:o=(a=new AudioContext).createOscillator();q=o.frequency.value=(t&t<<4^t)%897;x.fillStyle=R(q%255,0,q/3);x.fillRect(t%2048-q/2,q,z=t?q:2e3,z);o.connect(a.destination);o.start();

Also, i found a way to stop it, just press shift. (or any other key with a value too high or low to hear (At least i think that's what happens))

u/f8f82804

I've just spent a long time running this down, but with firefox-62/ubuntu-18, I have an issue where garbage is spoken at the end of each emoji name. The issue is an unterminated string copy in espeak-ng which should be fixed in newer versions; see https://github.com/espeak-ng/espeak-ng/issue…

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/
