Wondering if anyone can help me with this strange issue.
My imported sounds into Unreal are playing a few dB quieter compared to the raw assets outside of Unreal. We have even managed to find the hidden -3dB project-wide gain reduction in the WindowsEngine.ini file. But even with that set to 0dB, audio files are simply playing quieter that I’d expect. This is adding a bit of confusion when trying to understand the details of our loudness structures.
Hi,
The first thing that comes to mind is how Submixes work in Unreal.
Each Submix has Dry Level and Wet Level parameters. In Project Settings, the Master Submix description states that all sounds are routed through it. By default, the Dry Level is set to –96 dB, which effectively makes the sound quieter.
There are also MasterReverbSubmix and MasterEQSubmix. In a basic template project, sounds are routed through the EQ Submix by default, but not through the reverb (this is likely controlled by a send). The EQ Submix is connected to the Master Submix and is also set to –96 dB, which means the signal is effectively attenuated twice.
To check whether this is the source of the issue, try setting the Dry Level to 0 dB on both the Master Submix and the EQ Submix.
From what I’ve observed, the Master Submix and Reverb Submix always need valid values assigned in Project Settings. If you clear them and restart the project, they are automatically restored to their default settings. This suggests that simply removing them from the audio path is not a supported option.
This is just a guess, but it sounds very close to the issue you’re describing.
I hope this helps.
Best regards,
Gustaw
Is this a mono file?
