Finally tried stacking audio clips from a ghost hunt and got a clear voice response

I've been ghost hunting with my team for about 2 years now. We always record EVP sessions but most of it is just static or background noise. Last month we were investigating an old schoolhouse in Ohio and I caught something faint on my recorder. Instead of just amplifying it like usual, I tried stacking 5 recordings of the same spot on top of each other in Audacity. The noise cancelled out and I got a clear whisper saying "get out." Not saying it's proof of anything but it made me wonder how many other EVPs we've missed. Anyone else try this method or have better tricks for cleaning up audio?

Oh man, I've been down that exact road. Stacking audio is a solid technique, I've done it with four or five passes in Audacity too and it can really pull whispers out of the noise. One thing that helped me was tweaking the gain on each layer a little different before stacking, it stops the same background hum from just getting louder. Also try a high pass filter around 300 Hz before you stack, cuts out a lot of the low rumble that masks softer voices.

Man, I had a buddy who tried to clean up a recording of his granddad telling old war stories. The original was basically just static with a faint voice. He stacked six layers and it sounded like a creepy choir of ghosts at first. Ended up just using three passes with different EQ settings and it came out clear enough to hear the punchlines.
