Is your feature request related to a problem? Please describe. Our sound system can be enhanced and made more flexible and efficient. In addition, different kind of audio quality features can be added, in terms of Quality-of-Life.

Describe the solution you'd like For the library, we may use OpenAL in place of native Java AudioSystem, then we can have more in-depth compatibility supports and advanced audio behaviors. For the in-world behavior, the audio effects can be played reflecting the distance and even the direction (with respect to the top-down south-north player's view), by the volume and direction, dynamically. Furthermore, we may even try to have 2/4/5/7 channel support as for the positional audio support, or even 2.1/4.1/5.1/7.1 sound source supports.
