Communication Outposts: Unknown Origin

Communication Outposts: Unknown Origin is a cinematic sci-fi sound effects library exploring the unsettling world of unidentified communications, mysterious transmissions, alien signals and strange radio frequencies.

Built as a semi-modular library based on layers of static, electromagnetic interference, electronic noise and unusual signal behaviour, this collection moves beyond conventional radio communications into something a little more disturbing. Strange tonal patterns emerge from the noise. Unfamiliar signals pulse through eerie frequencies. And buried within the static are traces of something that sounds disturbingly alive.

From communication arrays and active carrier signals to eerie pickups, emergency broadcasts, radar activity and unsettling non-human vocalisations, Unknown Origin explores the boundary between electronic interference and something far less familiar.

Whether you're building an abandoned communication outpost, intercepting an unidentified extraterrestrial transmission or designing a terrifying moment of first contact, Unknown Origin provides a diverse collection of sounds to bring these unsettling scenarios to life.

Organised Into 9 Sound Categories:

BACKGROUND
Ambient background hums, background noise, background rumbles and mysterious alien-like atmospheres.

CARRIER SIGNALS
Active carrier signals, radio frequencies and sustained carrier tones designed to establish the presence of active communication systems.

COMPMISSIONS
A merged combination of static-based computer sounds and radar-based transmissions, including high-tech communication sequences, transmission pulses, hollow signals and electrical static interference.

EERIE PICKUPS
Unusual tonal pickups, mysterious communication arrays, eerie frequencies, signal winds and low static textures.

EMERGENCY CHANNEL
Active emergency tones, static alarm-like broadcasts, scanning sequences and frequency shifts, creating the atmosphere of a communication system attempting to tune-in, locate, or respond to something.

NOT HUMAN
Unsettling creature-like and human-like vocal transmissions hidden within the static. Featuring eerie whooshes, mangled voices, unidentified communications, disturbing signal pickups and mixed atmospheric sequences.

SIGNALS & BEEPS
Electronic beeps, sonar pings, radar scans, tracking signals, alien pulses, frequency patterns, distress signals and unusual unidentified signal activity.

STATIC CRACKLE
Radio crackles, static pops, and static walkie talkie sequences.

STATIC DRONES
Deep static textures, electromagnetic noise, sustained static drones, lost signals and extensive interference and variations.
