I had a situation where a client needed a sound louder in a stereo master so we added it as a stem on top of the original mix.
The track had some plugins on the main track that the new stem didn’t. When playing back live it sounds fine but when I render it the new stem sounds lower in volume and tonally different.
I assume this is down to some latency issue throwing off the phase.
Anyone experienced this where latency is calculated differently on an offline render?
I can just render it realtime to get around it but it makes me wonder what’s happening now on offline renders when using multitracks.
There were some UAD plugins on the main track so that might be the issue.
