Notes

Not all browsers with support for the Audio API also support media streams (e.g. microphone input). See the getUserMedia/Streams API data for support for that feature.

Firefox versions < 25 support an alternative, deprecated audio API.

Chrome support went through some changes as of version 36.

^* Partial support with prefix.
