Frequently asked
How does AlarmDJ handle audio file playback?
AlarmDJ uses standard web audio APIs to decode and play uploaded files. It supports common formats like MP3 and WAV but requires users to provide their own audio content. The tool does not include a built-in library, so users must prepare files beforehand.
How does the scheduling feature work?
Users set specific dates and times for alarms through a form interface. The tool uses the browser's local clock to trigger playback. While it can handle multiple alarms, it does not support complex recurrence patterns beyond simple daily or one-time settings.
How do I set up a custom alarm for a specific day?
Navigate to the scheduling section, select the desired date and time, upload your audio file, and enable the alarm. The tool will trigger playback at the specified time. For repeated alarms, set the date to a future occurrence and adjust the recurrence settings manually.
How does AlarmDJ compare to built-in alarm apps?
Unlike native alarm apps, AlarmDJ offers full audio customization but lacks features like vibration or gradual volume increases. It excels in flexibility for users who want to integrate personal media but requires manual setup compared to automated smartphone alarms.
What should I do if my audio file isn't playing?
Verify the file format is supported (MP3/WAV) and check for corrupted data. Ensure the file size is within browser limitations. Test playback in a different browser or device. If issues persist, try re-uploading the file or converting it to a compatible format.
