/****************************************************************
* Class - AudioHandler
*
* This class wraps the different audio output options for
* pinball machines (WAV Trigger, SB-100, SB-300, S&T
* -51, etc.) to provide different output options. Additionally,
* it adds a bunch of audio management features:
*
* 1) Different volume controls for FX, callouts, and music
* 2) Automatically ducks music behind callouts
* 3) Supports background soundtracks or looping songs
* 4) A sound can be queued to play at a future time
* 5) Callouts can be given different priorities
* 6) Queued callouts at the same priority will be stacked
*
*
* Typical usage:
* A global variable of class "AudioHandler" is declared
* (ex: "AudioHandler Audio;")
*
* During the setup() function:
* Audio.InitDevices(AUDIO_PLAY_TYPE_WAV_TRIGGER | AUDIO_PLAY_TYPE_ORIGINAL_SOUNDS); // declare what type of audio should be supported
* Audio.StopAllAudio(); // Stop any currently playing sounds
* Audio.SetMusicDuckingGain(12); // negative gain applied to music when callouts are being played
* Audio.QueueSound(SOUND_EFFECT_MACHINE_INTRO, AUDIO_PLAY_TYPE_WAV_TRIGGER, CurrentTime+1200); // Play machine startup sound in 1.2 s
*
* Volumes set (pulled from EEPROM or set in setup routine):
* Audio.SetMusicVolume(MusicVolume); // value from 0-10 (inclusive)
* Audio.SetSoundFXVolume(SoundEffectsVolume); // value from 0-10 (inclusive)
* Audio.SetNotificationsVolume(CalloutsVolume); // value from 0-10 (inclusive)
*
* During the loop():
* Audio.Update(CurrentTime);
*
* During game play:
* Audio.PlayBackgroundSong(songNum, true); // loop a background song
* Audio.PlaySound(soundEffectNum, AUDIO_PLAY_TYPE_WAV_TRIGGER); // play sound effect through wav trigger
* Audio.QueueSound(0x02, AUDIO_PLAY_TYPE_ORIGINAL_SOUNDS, CurrentTime); // Queue sound card command for now
* Audio.QueueNotification(soundEffectNum, VoiceNotificationDurations[soundEffectNum-SOUND_EFFECT_VP_VOICE_NOTIFICATIONS_START], priority, CurrentTime); // Queue notification
*
* End of ball:
* Audio.StopAllAudio(); // Stop audio
