Audio player in iPhone

Audio player:-

Audio and video is quite common in the latest devices. An instance of the AVAudioPlayer class, called an audio player, provides playback of audio data from a file or memory. It is supported in iOS with the help of AV Foundation.framework and Media Player.framework respectively.

// How to get resources file path:

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

NSString   * path  =  [[ NSBundle  mainBundle]

PathForResources  : @  “or   Enduko emo” Of Type :@ “MP3”];

NSURL    * URL   =  [ NSURL fileURLwithpath :path];

Av AudioPlayer   *  audioPlayer    =   [[ AVAudio player  alloc]

                  Init WithContentsof   URL:url    error :nil];

// Setting Volume:

[ audioplayer  set volume  :1]  //   0 to 1  (max value is 1)

// Repeat play:

[ audioplayer  setNumberofLoops:2];

// prepare  to play:

[ audioplayer  PrepareToplay];

// setting  delegate:

[  audioplayer  setDelegate: self]

// playing

[ audioplayer  play];

// pause:

[ audioplayer   pause];

// stop:

[  audioplayer stop];
