In the year 2018 of our lord requiring that a specific version of a single browser being installed to see a website should earn you a special place in hell.

Its an experimental playground. I think you may be overreacting slightly.

AudioWorklet is part of the proposed W3C Web Audio API standard.

What does that comment add? Someone hacked something off a relatively fresh API and done something cool with it, the hint is in the name, hacker news.
zeth___
Hackernews, not "install proprietary software to have a peak at a walled garden" + "news".
jhoh
So every Show HN Post hast to run on open source software or else it isn't hacker news worthy? That doesn't sound right to me.

That is not as far fetched as you make it seem

Would be a cool addition to let users upload an mp3 and then act on it with the AudioWorklet to do stuff like bit crushing.

Great idea! Have implemented it, refresh and check it out.

This is pretty sweet. It'd be cool to have more examples though like square wave, triangle wave, etc. and maybe some simple effects like tremolo.

    let amp = 0;
    const maxamp = 0.5;
    const freq = 880;

    function loop(numFrames, outL, outR, sampleRate) {
        const steps = sampleRate / freq;
        const delta = maxamp/steps;
  
        for (let i = 0; i < numFrames; i++) {
            amp += delta;
            outL[i] = amp;
            outR[i] = amp;

            if (amp > maxamp) amp = 0.0; 
         }
    }

Only available on Chrome and only versions 66 and up.

Just relaunch your browser, it should update automatically.
jstimpfle
To state the obvious, not everybody has Chrome, and not everybody has or wants the newest version. That's how it should be. By implying that it's ok to assume otherwise, you're (probably unknowingly) harming the community.
elvinyung
Dumb (but genuine) question: why is it good that not everyone wants to be in the new version?
jstimpfle
Just try not to presuppose more than is required. I might be unhappy with the newest version. Or, my device can't be updated due to technical or polital reasons. Or, the newer version does not work or is not available for my hardware or operating system. Or, I might actually be on a fork (or fake) of the software that isn't up-to-date yet. You see, there are tons of reasons...
sgt
In Chrome's case, I believe it auto updates. So you don't really have a choice unless you actively try to disallow it or switch of auto-updates.
jstimpfle
So I do have a choice, right? HN is a pretty technical forum -- not normally a place for ignorant-consumer type viewpoints (no offense intended). Case in point, my version of "Chrome" (chromium on Debian) does not auto-update (I think so - It's the normal way on Debian, although I don't really use chromium but firefox).
jcims
Why don’t you go ahead and restate what sgt said in a way that wouldn’t have set you off on this needlessly perjorative tangent.
jstimpfle
Sorry, I'm just bad at leaving posts below my own ones unanswered. But actually I explained exactly what I thought was wrong with that (sgt's) comment and why I supposed it had been downvoted. I don't think there is a way of restating it -- OP has a perfectly valid point that does not need "nothing is wrong, just restart or install this thing that everybody needs to have" type rebuttals.

It hasn’t passed certification by your IT departments employer

For cutting edge html5 we have no choice but the latest chrome. Audio worklets? Webmidi? Even though I prefer Firefox they're not moving at the same rate as chrome, no one is when it comes to things like audio worklets.

Apparently there is no issue when it is Google doing it.

Lame. You are in a tech forum with techies and you are complaining about having to run the latest & greatest. How is this constructive?

Sometimes you need to run the newest stuff in order to, you know, use the newest stuff. As a techie, you should know that, right?

The alternative would be flash, but then you couldn't have done this demo....

indescions_2018
This is awesome. Sounds quite in tune at 440 Hz (A4). Could be the beginning of a DAW for Chrome ;)

Only available in Chrome 66+, and why do you submit it twice in a week?

Audio Worklet https://developers.google.com/web/updates/2017/12/audio-work... is way, way cooler than these demos imply, as it actually gives you a high-priority digital signal processing thread separate from the UI thread. And because it can benefit from WebAssembly, it's only a matter of time before the power of native audio applications is ported to the browser.

This thread https://forum.juce.com/t/juce-plugins-in-webassembly/25255 , particularly the demo here https://webaudiomodules.org/demos/wasm/dexed.html (try using the ZXCV row on your keyboard) are incredibly promising, as they're straightforward ports of real synthesizers.

Other comments have mentioned that this is coming to Firefox as well; core contributors on the media team have been discussing how it's a priority as recently as two days ago: https://bugzilla.mozilla.org/show_bug.cgi?id=1062849

Really exciting times for the web audio space!
