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. 

Add the AVFoundation frame work.

Capture 15// 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];


Capture 15// Setting Volume:

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


Capture 15// Repeat play:

[ audioplayer  setNumberofLoops:2];


Capture 15// prepare  to play:

[ audioplayer  PrepareToplay];

Capture 15// setting  delegate:

[  audioplayer  setDelegate: self]


Capture 15// playing

[ audioplayer  play];


Capture 15// pause:
