Case File #003 – The Ždziar Tape: A Forest Recorder Captured What Shouldn’t Exist
CASE ID: ZD-AUDIO-001
DATE LOGGED: October 7, 2015
STATUS: Archived / Active Review
LOCATION: Ždiar, Slovakia
🌲 Chapter 1: The Discovery in the Trees
In early October 2015, three hikers exploring a remote woodland trail near Ždiar, a village at the base of Slovakia’s High Tatras mountains, came across a small abandoned backpack lodged under a tree stump. Inside, alongside a cracked thermos and a torn map, was a Zoom H2n handheld audio recorder — still powered on, battery flashing red.
Curious, the hikers turned it off and took it to a nearby police station.
What the authorities discovered after analyzing the data is now known as “The Ždziar Tape.” The recording has never been publicly released in full, but several short clips have leaked online. What’s on the tape remains unexplained.
📼 Chapter 2: Timeline of the Recording
The audio recorder logged over 92 minutes of uninterrupted recording.
- 00:00–02:34: Background forest ambiance. Birds, distant wind. The occasional footstep. Possibly the owner.
- 02:35–07:15: Sudden static pulses. Rhythmic distortions. No known wildlife matches the sound.
- 07:16–19:50: A low frequency hum begins. Infrasound, according to experts. Peaks at 17Hz — barely audible to human ears, but capable of inducing anxiety, nausea, and hallucinations.
- 19:51–26:10: What sounds like breathing. Wet, slow, close to the microphone — but no footsteps. No movement. Just breathing.
- 26:11–27:45: A whispering voice. Language undetermined. Analysts ruled out Slavic, Germanic, and Finno-Ugric roots. Some believe it may be reversed Latin.
- 27:46–...: Then — screaming. Not human. Something... wrong.
Audio engineers who examined the tape described the final 11 minutes as "inhuman in tone and impossible in acoustics." The microphone input registers shifts that suggest multiple sound sources moving in unnatural patterns — some circling the recorder at speeds that exceed human capability.
🧠 Chapter 3: Analysis & Reaction
The Slovakian Ministry of Environment initially treated the discovery as a hoax — until acoustic researchers at the University of Bratislava concluded the recording contained no evidence of digital tampering.
Experts from Austria and Germany later confirmed that:
- The infrasound waves are not present in commercial microphones by default.
- The breathing pattern is non-human in lung capacity and pacing.
- The final segments contain “acoustic anomalies” that violate physical sound modeling.
The backpack’s owner was never identified. DNA from the straps matched no missing persons. To this day, the recorder remains in custody under sealed documentation.
The case was quietly dropped in 2017 and marked as “Resolved (Inconclusive).”

👁🗨 Public Reaction
In 2019, a 4-minute leak titled forest_entity_v1.mp3 surfaced on a Romanian conspiracy forum. Though quickly removed, audio mirrors of the clip still exist in hidden corners of the web. Some claim listening causes migraines, panic attacks, and hallucinations.
No official agency has claimed ownership of the Ždziar Tape since 2018.
⚠️ Listen With Caution
If you come across the audio online, experts recommend using noise filters and low volume, and never listening alone at night.
