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/

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

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

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
