Try the switches. This only changes the picture.

Step-by-step guides in English and Thai, from first install to karaoke with friends.
Read the guidesDo I need an account?
No. Every plug-in works fully without one. An account adds permanent links, your name and photo for friends, and settings that follow you.
If my internet drops, do viewers still hear me?
Yes. Audio goes from your DAW to OBS on your own computer. Only friends singing over the internet need a connection.
How much delay does it add?
About one DAW buffer, for example 5.3 ms at 256 samples and 48 kHz. The Hub shows the exact number next to the OBS status.
Which DAWs does it work with?
Any DAW that loads VST3 on Windows. We test Studio One, Cubase, Reaper, FL Studio and Ableton Live.
