"IAP Plays" is a computer software that facilitates public address announcements with features like manual and autoplay announcements, automatic background music fade, date-time validity checking, and day-part volume changes.

But that's just the beginning. IAP's user-friendly interface and intuitive design make it incredibly easy to play recorded PA announcements. Users can also schedule automated playing of announcements or set intervals for them. Furthermore, for businesses with multiple users, IAPremote enables all network users to play and make announcements from their desks.
Other features include automatic background music fade when an announcement is playing, optional chimes with microphone paging, date and time validity checking for announcements, and automatic day-part volume changes for both announcements and background music.
