Class: AuralAlertSystem

A system which manages and plays aural alerts using a priority queue system.

The system collects registered alerts, and manages how they are played. Each alert belongs to a queue. Only one alert from each queue can play simultaneously. Alerts are queued to be played when they become activated or triggered. If two alerts are queued at the same time, the one with higher priority is played first. Alerts cannot interrupt an already playing alert, regardless of their relative priorities.

wake​

▸ wake(): void

Wakes this system. If the sound server is also awake, all active continuous or repeating alerts will be re-queued to play.

Activation of any alerts that were already active when the system woke up will not queue them to be played unless the alert was deactivated in the interim.
