I can’t use FastPlayground on Firefox 117 on Linux. The reason seams to be Cross-Origin Request Blocked.

Hey cwilso,

Sorry for posting a general audio question here but you're probably the only person who knows how to do this.

I have some audio elements, effects, and a microphone from getUserMedia, and I'd like to send all of this output to WebRTC and to MediaRecorder.

The problem is that I can't find any documentation on creating MediaStream objects and sending data to them, all the MediaStreams I can find come from some pre-existing source.

Hope you can help, and thanks in advance :)

Should show the code required for a particular graph.

Is there a live version anywhere other than http://webaudio-io2012.appspot.com/#10 ?

Hi! My name is Pedro Pablo Camellon. I just discovered the project and want to help. I know a little about UI/UX design, HTML, CSS, and JavaScript. I think it would be great improving how the app looks on mobile. I'd be really glad to contribute to the project.

It seems the pointer event handling/shim isn't quite right, as mouse events are ignored and there are no pointer events delivered. This means that it's impossible to add any elements to the canvas. Altering setClickHandler to just put the handler on mousedown resolves not being able to add elements, but doesn't fix the rest of the input.

I don't know if this is an issue on other platforms/browsers, this is the only platform I have to hand to test it. I also can't add elements in IE11, but I don't know if that's just because web-audio is unsupported there or if it suffers from the same problem.

On my iPad, none of the range sliders (like oscillator frequency) are working. After some poking around, I found that html5 range sliders would not work if added anywhere on the page.

Tracked it down to "pointerevents.js" - disabling that file allowed range sliders to work again - but it also breaks all the event handling code.

Looks like the version of pointerevents.js in repo is modified from original and minified too - so this is where I take a break...

This is great stuff! I would love to use portions of this code. Could you add a license to your code?
