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

is there anyway to stop this!!! ?

u/lionleaf

Man, I was not expecting sound. Is there a way we could make all sound dweets click to play/unmute?
u/f8f82804

I try really hard to make my audio dweets stop when you scroll away. Other than that, I'm not sure how to tackle it from the site side... With speechSynthesis we can just add pause() and resume() calls to the dweet pausing/resuming code (see https://developer.mozilla.org/en-US/docs/Web…). For AudioContext however, I think we'd need a set of bindings to create instances that register them with the dweet pause/resume hooks.
u/f8f82804

I also just realized that firefox won't mute speechSynthesis even though it shows an audio icon...
u/yonatan

Chrome won't mute it either.
u/katkip

That's genius
u/joeytwiddle

@f8f82804 The first stage, we can simply not autoplay audio dweets. https://git.io/fA2Bp

A speaking dweet (international version)

u/joeytwiddle

Chrome users, if your utterance goes over 15 seconds, you may need to close the tab. http://tinyurl.com/chrome-bug-679437
u/cantelope

very clever :)... btw, which dweet of mine crashed your lappy? ...just curious
u/joeytwiddle

This is the one, it can reliably overheat my CPU: https://www.dwitter.net/d/2355 I think it's due to the size of the large squares. I have had to adjust the cooling thresholds!
u/cantelope

:/ sorry about that.
u/joeytwiddle

No worries Cantelope. Wow Mac has a lot of voices. The "Cello" voice is pretty funny! https://codesandbox.io/s/vq48b #audio #speech
