Soundpool plays only first 5 secs of file. Why?

Question

I use Soundpool in my app, so far it works good, but I do have a wav file which is 10 secs. Unfortunately, soundpool plays only the first 5 secs. How to make soundpool to pl

Answer 1

SoundPool designed to play short sound effects. To play music (big audio files) you need to use MediaPlayer

// R.raw.audio_file - res/raw/audio_file.mp3

mediaPlayer = MediaPlayer.create(this, R.raw.audio_file);
mediaPlayer.start();

This activity is works for me

public class MainActivity extends Activity {

    private Integer soundID;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        this.setVolumeControlStream(AudioManager.STREAM_MUSIC);
        // Load the sound
        AudioManager audioManager = (AudioManager) getSystemService(AUDIO_SERVICE);
        float actualVolume = (float) audioManager
            .getStreamVolume(AudioManager.STREAM_MUSIC);
        float maxVolume = (float) audioManager
            .getStreamMaxVolume(AudioManager.STREAM_MUSIC);
        final float volume = actualVolume / maxVolume;

        SoundPool soundPool = new SoundPool(10, AudioManager.STREAM_MUSIC, 0);

        soundPool.setOnLoadCompleteListener(new OnLoadCompleteListener() {
          @Override
          public void onLoadComplete(SoundPool soundPool, int sampleId,
              int status) {
                      @Override
      public void onLoadComplete(SoundPool soundPool, int sampleId,
          int status) {
          soundPool.play(soundID, volume, volume, 1, 0, 1f);
          try {
            Thread.sleep(5000); // play twice
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
          soundPool.play(soundID, volume, volume, 1, 0, 1f);
      }
    });
          }
        });
        soundID = soundPool.load(this, R.raw.sound2, 1);
      //load fx
      //playing soundpool

    }
}

You must load you sound asynchrony and check audio cache - it can be overflow.

Its very heedful

Answer 3

We have solved similar problem by decreasing in our *.ogg effects sample rate. Our initial sample rate was 44 kHz ~ and only 10 sec of sound played, decreasing to 16 kHz increase playability to 30 seconds

Solution was found in this discussion

Answer 4

So I think you reached the 1M limit in SoundPool.

SoundPool is hard code the buffer size as 1M, for all loaded file, store in pcm format.

So it do not care of ogg or wav.

Answer 5

Your file is probably too large. Try to change from stereo to mono, if you do not need stereo anyway. Or try to downsample your file.

Reducing the filesice worked in my case.
