Preview the homepage sounds
These three short examples demonstrate synthesized tones. The homepage offers twelve sounds with its own in-app preview picker. Start with a comfortable device volume. Nothing plays automatically.

Built-in alarm sounds
Built-in sounds are the fastest choice and generally the most dependable in a browser. They do not depend on a third-party streaming service or a file remaining available elsewhere on your device.
Choose a sound with enough contrast from your normal environment. A gentle tone may suit a quiet room or a focus timer; a stronger repeating tone may be more appropriate for waking.
Your uploaded audio
Uploads let you use an audio file selected from your device. This can be music you have the right to use, a recorded cue, or another personal sound. The browser handles the file for use in the current experience; you should keep the original file as a backup.
- Use a file that starts promptly instead of several seconds of silence.
- Normalize very quiet audio before relying on it.
- Preview the beginning and confirm it plays through your intended speaker.
- Do not upload content you do not have permission to use.
Microphone recordings and spoken messages
A spoken alarm can communicate context that a generic beep cannot: “Leave for the airport,” “Start the oven timer,” or “Call the office.” Your browser will request microphone permission when you start recording.
Record in a quiet space, speak clearly, and test the result. A short message is usually easier to understand immediately after waking than a long one.
Media and streaming links
Music and streaming services control whether their content can start automatically. They may require an account, an open app, or a manual click. A media link is therefore less predictable than a built-in alarm tone.
Clock modes
The available visual modes are more than decorative skins: they offer different ways to read and experience time. Choose the display that is easiest to understand from your desk or sleeping position. The alarm engine and sound choices remain available across clock styles.
Timer, stopwatch, and world clocks
Timer
Use a timer for a duration rather than a specific time of day—cooking, focused work, breaks, or short routines.
Stopwatch
The homepage stopwatch measures elapsed time and supports laps. The standalone stopwatch provides Start, Pause, Resume, and Reset without lap history.
World clocks
World clocks help compare times across locations. Confirm time zones before scheduling a meeting or travel reminder, especially around daylight-saving changes.
Sleep sounds
Sleep sounds are intended to support winding down and can fade out on their own. Keep their volume comfortable and separate from the louder alarm sound you expect to wake you.

Sound credits and permissions
The built-in homepage alarm library and routine tools use original, programmatically synthesized tone and noise patterns. Birds, coffee, rain, and waves are synthetic sound effects, not third-party field recordings. Browser Web Audio features generate them locally; these built-in sounds require no recording attribution or external audio stream.
Uploaded audio, microphone recordings, and external media links are supplied by the person using those features. Use only material you own or have permission to use. This site does not grant rights to music or recordings from another service. Contact hello@alarmclock.live with sound suggestions or a rights concern.
