Not to be overly negative but thats lunacy. What you described is best served as a native application. Web browsers were supposed to be information viewing programs. Not virtual machines. I know it makes portable applications easy but the smash a VM into a text viewer is such a horribly broken idea and is why we have this security nightmare.

Nothing about this is a virtual machine. It is an API that exposes a lower-level Audio interface. I don't need to spawn a virtual machine or mess with any DLLs or figure out libraries because I can simply load a browser. Nothing is saying this needs to be on a remote server, it can be a local .html file for all it matters.

But hey some of us still run around with MS-DOS 5.22 on that new Spectre-ridden, rowhammer-ready i7 because DOS/4GW is hella stable.

> Web browsers were supposed to be information viewing programs.

True if we stopped thinking at 1996. I don't know how to tell you but browsers become application platforms not document delivery vehicles in the last 20 years.

There's plenty of sites doing this already like https://soundtrap.com
