Hello,

I'm noticing a strange metallic, digital artifact in SDRTrunk recordings in Nightly 2025-11-29. When using SDRTrunk Nightly 2025-3-22, I get no such artifacts. I'm attaching two sample calls of the same calls captured on two different machines running the two versions of SDRTrunk (The only difference between the two machines is the version of SDRTrunk Nightly 2025-11-29, and Nightly 2025-3-22).

Happy to provide any additional information and test further if needed.

Thanks!

Yes, and users reported the same on the Discord group as well. I'll look into it.
