Debugging a Jni So File and Getting some data

I have a Android Jni So file, I attached the file already, so you can check it. I need to get wav data of instruments from this So binary file. I think you must have experience and knowledge in ARM assembly and Jni debugging, and Midi structure in order to complete this project. Please check so file and some result wav files, let me know if you can do it. Thanks. So file - [login to view URL] Sample output - [login to view URL]
