t?o.frequency.value=300*1.06**'994577542225997544457799552'[t*6&31]:o=(a=new AudioContext).createOscillator(),o.connect(a.destination),o.start() is 4 bytes over but sounds better.

Excellent! #audio #music For anyone who wants the sound to stop, just scroll down to the next dweet then hit Reload.
u/joeytwiddle

It sounds good enough with 200 instead of 99 but +1 over
u/alien

It seems like Safari plays dweets significantly slower until you tap on them... Giving the iframe focus increases the request animation frame rate.
