Live stream from android to PC (Need app)

Hello, I just need an Android app (free or paid) to start streaming my concerts live for the fans , so I use my cellphone, and it goes directly to an IP adress where people can watch and lsiten.

Only requirement, AUDIO AND VIDEO MUST BE SYNCHED.

I've tried some apps, and while video is ok, audio is delayed over 1 seconds, and it doesn't work.

Both need to be synched, doesn't matter if BOTH have a delay of whatever seconds after they are recorded (like if I play a chord, sound and video can be delayed even 10 seconds or more, but TOGETHER).

Any help?
