Opus is now in preview builds behind a flag. Please see https://blogs.windows.com/msedgedev/2016/04/18/webm-vp9-and-opus-support-in-microsoft-edge/Tony commented
I would like to see Opus & .wav audio-tag support added to IE11 - which is a surprisingly good browser now (for both user and web-developer).
Microsoft & IBM developed the .wav format, so licensing should not be a problem. It may not be optimal for the web but we use.wav for telephone announcements and we cannot use other formats (external dependency). To find that FF & Chrome can support .wav but IE11 cannot is both disappointing and frustrating.Tony supported this idea ·
