How to Sync Sounds using SoundPool

问题

I have been trying to get a few sounds to play at the same time; currently i'm using a shared instance of SoundPool. I would like 1, 2 or 3 sounds to be played at the exact same time with no lag.

When calling SoundPool.play(...) X number of times in succession, the sounds are played in that order as one might think. what is the proper what to achieve this where i can prepare all of the sounds to be played at the same time and then play them as one?

Sudo Code:

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

_soundPool.load(_context, soundId1, 1);
_soundPool.load(_context, soundId2, 1);
_soundPool.load(_context, soundId3, 1);

_soundPool.play(soundId1, vol, vol, 1, 0, 1f);
_soundPool.play(soundId2, vol, vol, 1, 0, 1f);
_soundPool.play(soundId3, vol, vol, 1, 0, 1f);
