VTubers and VSingers! ⚠️ If you use OBS to mix your audio, it is messing up your vocal sync and making you sound OFF BEAT! ⚠️ You get a RANDOM offset every time you restart OBS, of 30ms or more. There is NO WAY around this as long as you use plain OBS (without dedicated mixing plugins) for your inst/vocal mixing. If you have separate sources in OBS for your mic/inst, you are affected. OBS monitoring won't help you notice, because it has its own DIFFERENT random offset! This screenshot is showing recordings made with OBS on Windows 10, with both MIC and BGM audio sources coming from VAIO virtual cables, driven by the same VoiceMeeter instance. This is the BEST possible scenario. With different audio source types, it could be even worse! This happens because OBS does NOT do ANY synchronization of audio coming from different sources. It just YOLOs it, so every time you start up OBS, the audio input from each source starts at a different point in time. You can adjust the sync, but next startup it'll change.
