Adding Custom MP3 Sounds
To add custom MP3 sounds, follow these steps:
1. In Control Panel, click on the Documents and Media section.
2. Click the Add button and Select Basic Document.
3. Under the File section click Choose File and pick an MP3 file to upload.
Since this interface lets you add any type of media, no validation of the file occurs, however Audible Alerts only displays audio/MP3 mime-types.
4. Give the new MP3 a short title. For example, if you upload cowsound.mp3, call it Cow Sound
5. Click Publish.
If you Navigate back to the Alarms Portlet and click the Settings button again you should now see your new Alert to select.
