The Acoustic Predator

The first thing the woods took from Sylas Renn was his wedding ring. Not its physical form - the platinum band remained on his finger - but the sound of it. The faint, definitive click it made against his ceramic coffee mug each morning, a tiny percussion of habit and home. He’d been listening to the playback from his overnight microphones in Halvarth Wood when he heard it: that familiar click, perfectly rendered, nestled between the hoot of a tawny owl and the rustle of a fox. The owl and fox had been outside his tent. The mug and the ring had been inside his sleeping bag, forty miles away in his empty house.

His own life was being archived in a forest he’d just entered.

Sylas, a man who made his living recording the death-throes of ecosystems, sat frozen in his tent, the headphones sealing him into a terrifying new reality. This was not pareidolia, the mind hearing patterns in noise. This was predation. The ancient woodland wasn’t just alive; it was acoustically carnivorous, and it was digesting him. The local warning - don’t go in, and if you see the Green Lady, don’t answer her - had been a grotesque understatement. The horror wasn’t a spectre you saw. It was the one already listening to you, learning your frequencies, and playing them back to you from the dark.

The email from the property developer was slick with corporate concern. …a unique opportunity to preserve the acoustic heritage of Halvarth Wood ahead of sensitive sustainable development… Dr. Sylas Renn, adrift in his cluttered university office surrounded by hard drives full of extinct dawn choruses, felt the old, cold fury. They weren’t hiring him to preserve a soundscape. They were hiring him to perform its autopsy, to provide the respectful ambient soundtrack for its obituary.

His ex-wife, Leah, had called it his “museum of loss.” “You don’t record life, Sylas,” she’d said, the last time. “You record ghosts. You’re a taxidermist for noises.” She wasn’t entirely wrong. His life’s work was a library of endings: the last grind of a glacier calving, the final rasp of a rainforest tract before the chainsaws won. He documented the silence as it arrived.

The old farmer who leased the grazing land bordering Halvarth Wood handed him the key to the gate with a knotted, earthy hand. “Path’s clear to the old stone,” he said, not meeting Sylas’s eye. “Best be out by dusk.”

“I’ll be doing overnight recordings,” Sylas explained, patting his backpack of parabolic mics and windjammers. “The nocturnal activity is crucial.”

The farmer’s gaze flickered to the dense, brooding line of trees. It wasn’t oak and beech he saw. “Aye. Well. You mind yourself in there. And if you see her… you just leave her be.”

“See who?”

“The Green Lady. Some call her that. You’ll know if you do. Folk say she asks questions. You don’t answer. You just keep walking.”

A local superstition. A story to keep children from getting lost. Sylas offered a tight, professional smile. “I’ll be sure to keep my headphones on.”

Halvarth Wood didn’t greet him; it absorbed him. The modern world’s hum died within ten paces. It was replaced not by silence, but by a profound, layered presence. It was the difference between an empty room and a room where everyone has just stopped talking. The air felt thick, acoustic. His own footsteps on the sodden leaf litter were shockingly loud, an intrusion.

He found the “old stone” - a moss-blanketed monolith - and set up his primary recorder, its furry windjammer making it look like a sleeping beast. He placed secondary mics in a careful star-pattern, twenty meters out. This was his ritual: precise, clinical, a scientific listener imposing order on chaos.

The first night’s recording was technically flawless and sensorily unnerving. The expected sounds were there: the rustle of a badger, the whisper of the canopy. But beneath them, in the sub-bass range his equipment could parse but his ears could not, was a constant, low-frequency vibration, like the idling engine of the earth itself. And there were… anomalies. A ghostly wisp of children’s laughter, distant and crystalline, at 3:17 AM. Not from the village, the village was miles away, and asleep. A phrase in a guttural, melodic language - Cornish, but an older form than any revivalist spoke - at 5:02 AM. It wasn’t in the foreground. It was beneath the rustle of a fox, woven into it, as if the fox’s movement was playing a needle over a groove inscribed centuries ago.

He felt a prickle, not of fear, but of immense professional excitement. This wasn’t a habitat. It was an archive. The wood wasn’t just alive; it was remembering. His theory of deep acoustic imprinting, his life’s ragged hypothesis, was manifesting here. He spent the next day sleep-deprived and feverish, analysing spectral graphs. The laughter recurred, same time, same duration, a perfect loop. The language fragment was identical. This wasn’t random pareidolia; this was playback.

On the second afternoon, tired of protein bars, he decided to test a boundary. He spoke, clearly, toward a giant beech he’d designated “Mic Three.”

“Testing. One, two. This is Dr. Sylas Renn. The date is October nineteenth.”

He felt foolish. The wood swallowed the words.

That night, the playback changed.

At 2:08 AM, through his high-fidelity headphones, he heard it. First, the familiar ambient bed of night insects. Then, clear as a bell, his own voice: “Testing. One, two. This is Dr. Sylas Renn. The date is October nineteenth.” But it wasn’t a mere recording. In the spectral analysis, his voice was the carrier wave, but beneath it, woven into its very harmonics, was the children’s laughter. And beneath that, something new: a slow, rhythmic, damp sound he couldn’t identify. A spade in clay?

A cold knot tightened in his gut. The wood wasn’t just replaying. It was layering. It had recorded him, and was now integrating him into its permanent collection, stitching his voice into the same sonic strata as the laughter and the lost language.

The farmer’s warning echoed. You don’t answer.

But what if the wood was asking the questions? Not with a Green Lady, but with his own voice, thrown forward and back in time?

He should have left. Packed his gear and filed a report about “unique psychoacoustic phenomena.” But Leah’s ghost taunted him. Taxidermist of noises. Here was a place that defied taxonomy, that didn’t just hold ghosts but created them in real-time. He was no longer just a recorder. He was a participant. The scientist in him was terrified. The man who spoke to empty rooms was fascinated.

On the third day, the isolation pressed in. The wood’s acoustic density became a physical pressure. He found himself whispering, afraid to add more of himself to the sediment. He played back the previous night’s capture. There, at 4:55 AM, was a new anomaly. A voice, not his own. A man, local accent, thick with a fear so raw it was contagious: “…can’t find the path. She keeps asking. I won’t answer. Oh God, I can see the stone…” A crackle of dead leaves, a sharp gasp, and then the sound seamlessly blended back into the rustle of the actual trees.

It was a distress call from the past, perfectly preserved. A previous listener. The wood had him, too.

That evening, as a fog writhed through the trunks like searching fingers, Sylas broke. The loneliness was absolute. He was a man who spent his life capturing the voices of places, and now a place was capturing him, and there was no one to tell. He turned on his handheld recorder, not for science, but for companionship.

“Log. Day three,” he said, his voice hoarse. “The layering effect is accelerating. It’s not random. It’s compositional. I believe the wood’s acoustic memory is a physical property of the site, possibly linked to the mineral content in the stone and the unique humidity… It’s learning. It’s using my voice.”

He stopped, listening to the oppressive quiet. Then, the human need, vast and stupid, overwhelmed him.

“My name is Sylas Renn,” he said, too loudly. “I am here. Can anyone hear me?”

The fog swallowed the words. Nothing replied. He felt a fool. He packed his main rig, leaving only the secondary mics running, and retreated to his tent.

Sleep was impossible. The vibration was in his bones now. At 11:34 PM, it began.

Through his pillow speaker, connected to the live mics, he heard his own voice from the afternoon’s log: “It’s learning. It’s using my voice.” But it was changed. Slurred, desperate. And underneath it, the rhythmic damp sound was louder now. Thud… scrape… thud. And a new element: shallow, panicked breathing that was not his own, but which syncopated perfectly with his recorded speech.

Then, a clear, new sentence in his own vocal print, a sentence he had never spoken: “Why did you answer, Sylas?”

He ripped the headphones off. His heart was a trapped bird. It was a composite. The wood had taken his “Can anyone hear me?” and the lost walker’s terror and the children’s laughter and synthesized a new question, using him as the instrument.

He scrambled out of his tent into the fog-shrouded night. He had to get the primary recorder, the master file, and get out. The stone was a darker smudge in the gloom. His headlamp beam cut a feeble cone through the mist, making the trees seem to lean in.

As he reached the stone, the beam caught a figure.

Not a green lady. A man, his back turned, dressed in walking gear a decade out of style. He was moving in a slow, repetitive motion. Thud… scrape… thud.

The sound from the recording.

The man was digging.

“Hello?” Sylas breathed, the word leaving him before he could stop it.

The figure stopped. It didn’t turn. But Sylas’s own voice came from it, not from its head, but from the air around it, calm and horrible: “I’m looking for the path. Can you tell me the way?”

It was the wood. It had taken the lost walker’s intent, his own voice, and made a puppet. A question made flesh and sound. To answer was to give it more data, more of himself. To finish the recording.

You don’t answer.

You just keep walking.

But his professional instinct, the cursed need to document, fired. His hand, moving on its own, clicked on the handheld recorder in his pocket.

The figure began to turn, its movement stiff, a bad recording of a movement. Sylas’s voice leaked from the mist again, now edged with the children’s laughter. “Leah said you only collect ghosts. Is that what I am?”

Terror unlocked his legs. He turned and ran, abandoning his expensive equipment, crashing through bracken, the beam of his headlamp a frantic strobe. Behind him, he didn’t hear footsteps. He heard the layered playback - his running breaths, the laugh, the digger’s scrape, all mixed into a chasing symphony.

He found the gate, fell through it, and lay sobbing on the cool, normal grass of the pasture. The dawn light felt like a pardon. He drove home on autopilot, the woods' vibration still a phantom tremor in his teeth. For days, he moved through his sterile house like a ghost, jumping at the click of his own kettle. He deleted the files. He threw the hard drive containing the master recordings into the university’s industrial degausser. He told the property developer he’d found “nothing of note,” his voice a flat, dead thing.

A week later, a thick, creamy envelope arrived. Invitation to the Halvarth Grove “Community Visioning Presentation.” The developers were unveiling the final plans. A compulsion, sick and deep, pulled at him. He had to see it rendered safe. He had to see the monster mapped, paved, and neutered.

The presentation was in a sleek hotel suite overlooking the bay. Canapés and Prosecco. The lead developer, a man named Croft, gave a polished talk about “symbiotic luxury” and “heritage-sensitive design.” Sylas watched, numb, as renders flashed on the screen: glass villas nestled artfully between trees, a “sonic meditation walk,” a “historical echo garden.”

Then, Croft clicked to the final slide. “And to ensure our residents have a truly immersive connection to the site’s unique character,” he said, beaming, “we’ve partnered with a renowned sound artist to create an authentic, living soundscape for the community’s private audio guides.”

A familiar, pristine audio waveform appeared on the screen behind him. Sylas’s breath stopped. It was his. It was the clean, master-quality recording from his first night, the one he’d degaussed, filtered to isolate the most “evocative” elements.

Croft pressed play. Through the hotel’s high-end speakers, Halvarth Wood breathed into the room. The gentle night insects. The distant owl. Then, crystal clear and utterly out of context, the ghostly wisp of children’s laughter.

The room of potential buyers murmured, delighted. “Charming!” someone said.

“But that’s not all,” Croft said, raising a finger. “We’ve used cutting-edge AI to extrapolate and interact with this acoustic heritage.” He tapped his tablet. “Ask it about the wood.”

An assistant, smiling, spoke into a mic. “What can you tell me about the history here?”

The system processed for a second. Then, a voice responded. It was a warm, friendly, synthetic voice, but woven into its digital timbre, clear as a bell to Sylas’s trained ear, was the foundational grain of his own vocal print.

“The history here is deep and layered,” the voice said, a ghastly parody of his own professional tone. “Would you like to hear a story?”

The audience clapped. Croft looked triumphant.

Sylas stood up, his chair screeching. All eyes turned to him. He tried to speak, to shout a warning that would sound like a madman’s raving. But his throat closed. He saw not the developer, but the wood. It hadn’t been destroyed. It had been licensed. Its hunger had been given a corporate platform, a clean, wireless signal. It was no longer confined to a patch of trees; it was a product, ready to be piped into a thousand headphones, into the minds of wealthy buyers lying in beds where the badgers used to sleep.

And it was using his voice, the voice of the man who had come to bury it, as its welcoming host.

He stumbled from the room, the delighted applause for the wood’s digital ghost ringing in his ears. In the sanitized silence of the hotel elevator, he fumbled for his phone. His hands were shaking. He opened the voice memo app, a professional reflex. He needed to document this, the final, horrific perversion.

He held the phone to his lips, but no words came. Only a ragged breath.

The elevator descended. And from the phone’s tiny speaker, not from the recording, but as a live, generated response, a final, quiet sentence played back. It was in the warm, helpful AI tour-guide voice, the one built on his own stolen vocal cords.

“Don’t worry,” it said, soothingly. “We’ll find a use for that, too.”

The elevator doors opened onto the bustling, sunlit lobby. Sylas Renn stood frozen, the phone clutched in his hand, the last human listener in a world that had just learned how to listen back and was already curating its collection.

The Acoustic Predator is inspired by my novel ‘The Listener,’ a story about the profound connections we find when we truly hear the world and each other. This story exists in the haunted periphery of ‘The Listener's’ world, where the capacity to archive a soul is not a private grief, but a territorial hunger.
