Is it possible to set custom calendar notification sounds for each calendar event? I'm trying to create a custom notification sound for a single calendar event. For example, I want to use one mp3 for my reminder to take out the garbage, another for a birthday reminder, etc. 

Is this possible? My phone is an HTC One running stock 4.4.2

thanks
Download "File Manager (Explorer)" from Google Play List and explore "Notification" Folder.
Copy your custom file - MP3 ringtones in the "Notification" folder.
Open the Google Calendar --> General Settings --> Sounds --> You can find your custom file to select.


Hope this resolves your clarification.
