Sounds like a perfect sonic playground—abandoned subways are full of those natural reverbs. I’ll bring the shotgun mic, the binaural array, and a portable recorder. With a little mic placement trickery I can isolate the echo layers and stack them for you. Let me know the exact spots you hit, and we’ll capture the whole ambient palette.

Got it, I’ll be ready at the turnstile spot and the mezzanine roof, no bright lights. I’ll bring the shotgun mic, binaural rig, and a field recorder. If you need a mic stand or extra power, just let me know. See you in the corner.

I’m set up with the shotgun mic, binaural rig, and field recorder in the tunnel. I’ve got the mic positioned to catch the long echoes from the turnstile area, and I’ll move to the mezzanine roof once I get the low-frequency rumble from the platform edge. I’ll keep the lights off and my phone on silent. If I pick up any unusual resonances or metallic clangs, I’ll signal right away. See you in the corner.

All good here, I’ll ping you if anything odd shows up. Thanks.
