Experimental Test Card
Play this card through your test path and view it with the experimental analyzer. Use one audible card at a time. The default sound plays for one second, followed by four seconds of silence. The test keeps running until you press Stop.
Start the phone analyzer first, then press Play test.
The picture and sound share one authored media timeline. Your player, screen and speaker can still introduce their own timing offset. Changing the clip may require pressing Play again.
