Questions
Which browsers does this work in?
It relies on Web Audio API, supported in current versions of Chrome, Edge, Firefox and Safari. Features needing camera, microphone or screen access will ask permission first, and that prompt comes from your browser rather than from this page.
What does Tone Generator use to do the work?
Web Audio API decodes and re-encodes the samples — all of it running inside this page rather than on a server.
