Speed Control of MediaPlayer in Android

I am developing a player app and I am using MediaPlayer for that.

Now, I want to change the speed of the playing track.

I've seen so many apps with this functionality. How can I do this?

According to the flow that had mentioned here following codes are for android API 23 (Android 6.0 Marshmallow)

PlaybackParams playbackParams = new PlaybackParams();
playbackParams.setSpeed(2);
playbackParams.setPitch(1);
playbackParams.setAudioFallbackMode(
    PlaybackParams.AUDIO_FALLBACK_MODE_DEFAULT);
mMediaPlayer.setPlaybackParams(playbackParams);

Now you can use

mediaPlayer.setPlaybackParams(mediaPlayer.getPlaybackParams().setSpeed(speed))

for API 23 and up!

Beginning API 23, MediaPlayer can set playback speed using this method.

Class MediaPlayer

public void setPlaybackParams (PlaybackParams params) Added in API level 23

Sets playback rate using PlaybackParams. Parameters params PlaybackParams: the playback params. Throws IllegalStateException if the internal player engine has not been initialized. IllegalArgumentException if params is not supported.

Sample code:

MediaPlayer mp = ...; //Whatever
float speed = 0.75f;     
mp.setPlaybackParams(mp.getPlaybackParams().setSpeed(speed));

For API < 23, refer to Vipul Shah's answer above (or below).

The MediaPlayer does not provide this feature but SoundPool has this functionality. The SoundPool class has a method called setRate (int streamID, float rate). If you are interested in the API have a look here.

This Snippet will work.

 float playbackSpeed=1.5f; 
 SoundPool soundPool = new SoundPool(4, AudioManager.STREAM_MUSIC, 100);

 soundId = soundPool.load(Environment.getExternalStorageDirectory()
                         + "/sample.3gp", 1);
 AudioManager mgr = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
 final float volume = mgr.getStreamMaxVolume(AudioManager.STREAM_MUSIC);

 soundPool.setOnLoadCompleteListener(new OnLoadCompleteListener()
 {
     @Override
     public void onLoadComplete(SoundPool arg0, int arg1, int arg2)
     {
         soundPool.play(soundId, volume, volume, 1, 0, playbackSpeed);
     }
 });

soundpool only supports relatively small sound effect files that can be preloaded. You will get heap overflows with any useful length music track.

The MediaPlayer class doesn't give this functionality. Instead use the SoundPool class. It has a method called setRate (int streamID, float rate). Read this for further info. Here is a sample code for you to work with it.
