Yeah, I’ve been messing around with that kind of vibe. Think low‑freq hums that swell and shrink, like a slow metronome, then layer in filtered white noise that drifts in stereo. If you time the modulation with the shadow’s motion, the breath‑like pulse feels like the darkness itself is alive. The trick is keeping the envelope tight so the shadows don’t just vanish but glide into the ambush. Just make sure the low end doesn’t drown out the rest, or you’ll end up with a silent space instead of a breathing one.
