Apple’s AVFoundation framework includes AVAudioPlayer, an easy, feature rich, Objective-C based API for playing audio files.
An instance of the AVAudioPlayer class, called an audio player, provides playback of audio data from a file or memory.
Apple recommends that you use this class for audio playback unless you are playing audio captured from a network stream or require very low I/O latency. For an overview of audio technologies, see Audio & Video Starting Point and “Using Audio” in Multimedia Programming Guide.
Using an audio player you can:
- Play sounds of any duration
- Play sounds from files or memory buffers
- Loop sounds
- Play multiple sounds simultaneously, one sound per audio player, with precise synchronization
- Control relative playback level, stereo positioning, and playback rate for each sound you are playing
- Seek to a particular point in a sound file, which supports such application features as fast forward and rewind
- Obtain data you can use for playback-level metering
