Echo Demo

Demonstration of using AudioWorklets to read from the mic and echo it back. As of 2020-05 this depends on an API that is implemented in Firefox 76 and the Blink-based browsers: Chrome, Edge, Brave, and Opera.

Headphones are recommended, to avoid feedback. If it makes annoying noises, refresh the page to make it stop.

When ready, press any key. You'll need to give it permission to read from your microphone.
