Playing short .wav files – Android

by

The SoundPool is the correct class for this. The below code is an example of how to use it. It is also the code I use in several apps of mine to manage the sounds. You can have as may sounds as you like (or as memory permits).

public class SoundPoolPlayer {
    private SoundPool mShortPlayer= null;
    private HashMap mSounds = new HashMap();

    public SoundPoolPlayer(Context pContext)
    {
        // setup Soundpool
        this.mShortPlayer = new SoundPool(4, AudioManager.STREAM_MUSIC, 0);


        mSounds.put(R.raw.<sound_1_name>, this.mShortPlayer.load(pContext, R.raw.<sound_1_name>, 1));
        mSounds.put(R.raw.<sound_2_name>, this.mShortPlayer.load(pContext, R.raw.<sound_2_name>, 1));
    }

    public void playShortResource(int piResource) {
        int iSoundId = (Integer) mSounds.get(piResource);
        this.mShortPlayer.play(iSoundId, 0.99f, 0.99f, 0, 0, 1);
    }

    // Cleanup
    public void release() {
        // Cleanup
        this.mShortPlayer.release();
        this.mShortPlayer = null;
    }
}

You would use this by calling:

SoundPoolPlayer sound = new SoundPoolPlayer(this);

in your Activity’s onCreate() (or anytime after it). After that, to play a sound simple call:

sound.playShortResource(R.raw.<sound_name>);

Finally, once you’re done with the sounds, call:

sound.release();

to free up resources.
