The Media.pause() method (part of the MediaRecorder API) 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 is "inactive", raise a DOM InvalidState error and terminate these steps. If not, continue to the next step.
  2. Set MediaRecorder.state 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 MediaRecorder.pause event.




An InvalidState error is raised if the pause() method is called while the MediaRecorder object’s MediaRecorder.state is "inactive" — the media recording cannot be paused if recording is not occurring, and if it is already paused, pause() will have no effect.



 pause.onclick = function() {
     console.log("recording paused");
