For the first time, Chrome, Firefox and Edge can “talk” to each other via WebRTC and ORTC. Check the demo on Microsoft’s modern.ie testdrive.
tl;dr: don’t worry, audio works. codec interop issue…
| Feature | Interoperability | Notes |
| ICE | yes | Edge requires end-of-candidate signaling |
| DTLS | yes | |
| audio | yes | using G.722, Opus or G.711 codecs |
| video | no | standard H.264 is not supported in Edge yet |
| DataChannels | no | Edge does not support dataChannels |
As a reader of this blog, you probably know what WebRTC is but let me quote this:
WebRTC is a new set of technologies that brings clear crisp voice, sharp high-definition (HD) video and low-delay communication to the web browser.
In order to succeed, a web-based communications platform needs to work across browsers. Thanks to the work and participation of the W3C and IETF communities in developing the platform, Chrome and Firefox can now communicate by using standard technologies such as the Opus and VP8 codecs for audio and video, DTLS-SRTP for encryption, and ICE for networking.
