Broader OGG support is now in development: https://developer.microsoft.com/en-us/microsoft-edge/platform/status/oggcontainer/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 ·
