Use an audio stop timer
An audio timer tells the player when to stop. It does not detect whether you are asleep, identify a sleep stage or guarantee that a device will keep running in the background.

A worked example
Choose a 15-minute sound session and check the controls before settling down. Pause should stop both the session clock and audio; Reset should return to the chosen duration. If your device suspends the browser when the screen locks, the timer can be delayed. Use a dedicated alarm if you need a reliable wake-up signal.
Try it in three steps
- Choose a duration and comfortable volume.
- Test pause and reset while awake.
- Keep the limitations of background tabs in mind.
What to watch for
Do not depend on this browser tool for an alarm, medical monitoring or a safety-critical reminder.
Apply it to your own material
Try one scene or sound with a short duration, then adjust or stop according to your preference. The controls work independently, so motion, audio and the timer can each fit the moment.
