AudioPlayer properties

name

The name of the sound. This is either the name that was passed to the init, or the last path component of the audio file.

URL

The absolute URL of the audio file.

completionHandler

A callback closure that will be called when the audio finishes playing, or is stopped.

playing

Is it playing or not?

duration

The duration of the sound.

currentTime

The current time offset into the sound of the current playback position.

volume

The volume for the sound. The nominal range is from 0.0 to 1.0.

numberOfLoops

Number of times that the sound will return to the beginning upon reaching the end.

  • A value of zero means to play the sound just once.
  • A value of one will result in playing the sound twice, and so on..
  • Any negative number will loop indefinitely until stopped.
pan

The left/right stereo pan of the file. -1.0 is left, 0.0 is center, 1.0 is right.

AudioPlayer methods

init(fileName: String) throws
init(contentsOfPath path: String) throws

These methods create a new AudioPlayer instance from a file name or file path.

func play()

Plays the sound. Has no effect if the sound is already playing.

func stop()

Stops the sound. Has no effect if the sound is not already playing.

func fadeTo(volume: Float, duration: NSTimeInterval = 1.0)

This method fades a sound from it's current volume to the specified volume over the specified time period.

func fadeIn(duration: NSTimeInterval = 1.0)

Fades the sound volume from 0.0 to 1.0 over the specified duration.

func fadeOut(duration: NSTimeInterval = 1.0)

Fades the sound from it's current volume to 0.0 over the specified duration.

Notifications

SoundDidFinishPlayingNotification

This notification is fired (via NSNotificationCenter) whenever a sound finishes playing, either due to it ending naturally, or because the stop method was called. The notification object is an instance of the AudioPlayer class. You can access the AudioPlayer class's name property to find out which sound has finished.
