You are here API - How To is a service that provides ambient sounds for real-time events. It can be a way of providing event notifications to one user or many users across a network. Because each event has its own sound, users can keep track of what's going on without having to change windows or read notifications. Sounds generally come in sound packs, which users can switch between at will. Users can have come up with an appropriate sound for each event or choose a specific sound to play regardless of the sound pack being used.
