Recording pro vocals

Hey everyone,

I’ve been struggling with a mid maybe high-frequency ringing noise in my vocal recordings when I start pushing my voice. Let me say that in studio this doesn't happen. I can’t figure out what’s causing it, and I need some advice.

My Setup: • Acoustic Treatment: DIY acoustic panels • 6 panels (180 cm x 16 cm x 58 cm, with 2 layers of earth wool) • 1 panel (120 cm x 16 cm x 58 cm, with 2 layers of earth wool) • 2 square panels (58 cm per side, 16 cm depth, with 2 layers of earth wool) • 12 fiberglass panels (2 inches thick, 30 cm per side) • Aston Halo Reflection Filter • Limitations: I can’t treat the ceiling, but the floor is carpeted. • Recording Chain: • Microphone: Warm Audio WA-CX12 • Preamp: Warm Audio WA73 (without EQ) • EQ: Warm Audio EQP-WA • Audio Interface: UAD Apollo Twin MkII • DAW: Logic Pro X on a 2012 MacBook Pro • Tracking Headphones: Audio-Technica ATH-M50X • Issue: As soon as I push my voice, I hear a harsh, high-frequency ringing in my recordings. I don’t know if it’s coming from my room acoustics, power issues, or something in my recording chain. • Troubleshooting So Far: • Checked cables and connections (all balanced XLR). • Tried recording at lower gain—issue persists. • Adjusted mic placement—still there. • Can’t treat the ceiling, but could that be the problem?

Here’s a sample of the vocal recording where you can hear the issue:

Has anyone experienced something similar? Any ideas on how to fix it? Thank you so much in advance for your answers.
