I’m hoping that maybe someone on here can help me with an issue that’s been driving me crazy.
Version = Nuendo 10 (version 10.2.20 Build 396)
Interface = RME Fireface UCX (Latest firmware & Drivers)
OS = Windows 10
Computer = Custom Dell
RAM = 64 gigs
CPU = Intel Xeon Gold 6134 @ 3.20 GHz, 8 Cores
Graphics Card = NVIDIA GeForce GTX 1080
So I’ve been working on some explosions for a video game lately and a couple days ago I noticed that my sounds were starting to have this clipping, crackling sound but my VU meters in Nuendo showed no signs of clipping. In fact, my levels were at -1 dB because of the limiter I had my audio going through. I figured that maybe I was hitting the limiter too hard so dropped the volume of all of my tracks and it seemed to help fix the crackling. But, because I lowered the volume so much, the threshold of the limiter wasn’t kicking in and my explosions lost all of their punch.
Next, I decided to try exporting with the clipping to see what would happen and when I listened to the audio in VLC Player and Sound Forge, there wasn’t any clipping present!
Finally, I decided to create a new, empty Nuendo project and place one loud explosion SFX file (stereo file, 96k/24-bit, peak 0 dB) in it to see what would happen. It still clipped. The VU meters in Nuendo weren’t clipping but when I opened the level meters for my Fireface UCX, there was heavy clipping on the main output channel. And the only way to stop the clipping was to bring down the Master Stereo Out fader to -6 dB.
Lowering the levels on my Fireface didn’t stop the clipping. Lowering the levels from the windows speaker icon in the lower right corner of the screen didn’t stop the clipping either. I also tried turning off Control Room to see if that helped and unfortunately it did not. Only lowering the levels in Nuendo worked; either on the track or on the master fader. This makes me think that there is a setting in Nuendo that accidentally got switched on and now my output is being boosted by +6 dB.
I’ve looked everywhere to try and find what could be causing this and I’m just plain stumped. Any help you all can offer would be greatly appreciated. My temporary fix for now is to mix with my Master Stereo Out set to -6 dB and then when I’m ready to export, I’ll just raise the fader back to unity gain. Then I have to check all of my exports in Sound Forge to make sure I didn’t introduce any unwanted distortion or clipping.
Thanks for taking the time to read this!
