Calendar Events Notifier Premium v3.7.214 is an amazing calendar application for Android users. This app provides recurring reminders for the calendar events and fully solves the issue.
With this app you can configure the sound, vibration type and their pattern, led color, repeat interval and much more for the alerts in your Google calendars.
Regular users can configure global settings, that are active for all the calendars, but PRO users can configure these options locally for each calendar.
You will need to set the sounds for each calendar, or a single overall sound for all calendars. You also need to disable notifications in your calendar application.
