It sounds like we are working on a similar application. I have placed the same question not too long ago and have received no definite answer so I ended up experimenting with all currently available choices; JetPlayer, SoundPool and the AudioTracker, in this order. I have rejected the JetPlayer almost immediately. It is much too high level. The SoundPools looked very promising since it does allow you to play concurrent sounds but I also found it too limiting. I settled down with the AudioTrack but, not surprisingly, it has its own limits. It's interface does not support the pitch/rate control but it does allow you to stream raw date which can be synthesized during the run time. The point I am trying to make is that you will have to experiment with all the options and see what works for you. What you need to do is to design your application in such a way (strategy pattern or such) so you can replace one implementation of the sound control layer with the other, as you experiment with the different options. Let me know how you are doing. Good Luck.
