Ogg Vorbis and Opus audio formats support [Firefox and Chrome support it]
Ogg Vorbis and Opus are free and open-source audio codecs with great quality. They are developed by Xiph.Org Foundation and IETF.
Opus codec provides the best quality (latest listening tests: http://listening-test.coresv.net/results.htm for 96 kbps and http://listening-tests.hydrogenaud.io/igorc/results.html for 64 kbps) and very low latency (http://opus-codec.com/comparison/ ).

shared this idea
OGG, Theora and Vorbis are now supported in the Fall Creators Update by installing the Web Media Extension from the Microsoft Store: https://www.microsoft.com/store/apps/9n5tdp8vcmhs
Long-term, we expect to expand distribution of the Web Media Extension package to all Windows 10 devices so that these formats become a trusted and reliable part of the web platform available to developers.
