I want to make a TeamSpeak 3 Musicbot in Java. But I don't find any Protocol from Teamspeak for the Voice transmission. And after searching for a Client API, for Java, I didn't find anything. Only for a ServerQuery but that doesn't help me I think. I only want the Client to connect to the Server and then plays a Song, though that wouldn't be that hard!
Maybe you Guys can help me?
Teamspeak does not have an official client-api. You can only use the Query-API and create plugins. As the Query-API does not support any voice-communication, that's not the way you should go. The (most) official way of creating a Teamspeak3 MusicBot would be to run a client on your server which has a plugin installed which allows you to play music (more or less a soundboard). Sinusbot is exactly built this way.
Another "unofficial" option would be to make use of unofficial reverses of the teamspeak-protocol and built you own client from these. If you want more information about this, this repository might help you (and look for other projects the creator pushed, they might help you too).
