MediaRecorder.pause()

The Media.pause() method (part of the MediaRecorder API (en-US)) is used to pause recording of media streams.

When a MediaRecorder object’s pause()method is called, the browser queues a task that runs the below steps:

1. If MediaRecorder.state (en-US) is "inactive", raise a DOM InvalidState error and terminate these steps. If not, continue to the next step.
2. Set MediaRecorder.state (en-US) to "paused".
3. Stop gathering data into the current Blob, but keep it available so that recording can be resumed later on.
4. Raise a pause event.

     console.log("recording paused");
