Minecraft SoundCenter v0.3
Please note that you will get a Java security warning by default. This is because I don't have an expensive trusted certificate. It does not mean that SoundCenter is unsafe to use (check the source code to convince yourself).
Java is blocking the applet? Want to get rid of the security warning?
Read the recommended Java settings page.
Are you still having problems running the applet?
Download the standalone Desktop Application instead.
