Hi, my name is Max Kokopelli. I’m a field recordist and sound designer. In this post, I’d like to share with you my free EMF sound library — recorded on one of the ships. I’m still working on it, and the first full version will be released soon.

If you’re interested in these kinds of sounds, you can follow the link and download them for free.

If you’d like to listen before downloading — here’s a SoundCloud link where I uploaded a few examples.

And if you’d like to see the recording process — here’s the YouTube link, where I try to update videos as new material comes in.

Work on the EMF library is ongoing! There are still a few devices to record, but I’m really looking forward to presenting it to you in the near future.

Hello everyone.

These five months on board a working vessel were not just work — they were movement inside a functioning system.

I’ve completed an EMF sound library recorded alongside real machines and real processes: electric motors, distribution panels, PLCs, HMIs.

I listened to what is usually not meant to be heard — the pulsation of circuits, the rhythm of controllers, the tension within the lines.

All of this has been shaped into a structured EMF library, compliant with the UCS standard, with clean and precise metadata.

If you’re looking for EMF with character and context — you know where to find it.

This EMF Sound Collection brings together three electromagnetic sound libraries recorded from real, operating electrical systems — ranging from power infrastructure and electric motors to interference patterns, pulses, and signal-based textures.

All material was captured from active shipboard equipment and covers a broad spectrum of electromagnetic sounds, including buzzes, hums, noise, mechanical motion, energy pulses, and complex signal interactions. The bundle offers a cohesive and versatile collection for professional sound design, post-production, and experimental projects.

Machina from the Sky is a collection of electromagnetic field recordings captured from electric motors of various sizes and applications.

The library features sounds recorded from active shipboard and industrial equipment, ranging from compact handheld battery-powered tools to large high-power industrial motors. The material captures electromagnetic activity produced during motor operation, including start-ups, shutdowns, and changes in operating modes.

All recordings were made from real, working equipment and reflect the natural behavior of electric motors, with no synthesis or artificial sound generation involved. The sounds have a distinct mechanical and energetic character, making them well suited for precise, detail-oriented sound design focused on machinery and technical motion.

The material has been carefully selected and prepared with an emphasis on signal clarity, structural readability, and practical usability in professional sound design workflows.

This library is well suited for:

machinery, mechanical, and technical sound design

sci-fi devices, drives, and energy systems

short electro-mechanical elements, layers, and accents

film, games, trailers, and experimental projects

Voices of the Ether is a collection of electromagnetic field recordings focused on interference patterns, pulses, rhythmic fluctuations, and noise-based phenomena captured using EMF recording techniques.

The library features a wide range of electromagnetic textures, recorded directly from active shipboard equipment, including unstable pulses, oscillating signals, digital noise, interacting power sources, and complex patterns created by overlapping and conflicting electronic systems.

All sounds were recorded from real, operating sources on board ships and reflect natural electromagnetic activity, with no synthesis or artificial sound generation involved. The material ranges from short, expressive events to longer, evolving structures.

This library is particularly well suited for:

sci-fi and experimental sound design

interface sounds, signals, and abstract electronic elements

energy textures, pulses, and layering material

film, games, installations, and multimedia projects

Current Soundscape is a library of electromagnetic field recordings captured from real, operating electrical systems, focused on authentic electric textures and environments.

The collection features a wide range of electromagnetic sounds recorded directly from active shipboard equipment, including power transformers, power supplies, distribution panels and related systems. While the core of the library is built around buzz, hum, and noise-based foundations, the recordings themselves cover a broad spectrum — from stable backgrounds to complex, dynamically evolving and layered textures.

These sounds reflect natural changes in electrical load, operating modes, and interactions between systems, giving the material a living, organic character rather than a static or artificial feel.

All recordings were made in real working conditions, with no synthesis or artificial sound generation. The material has been carefully selected and prepared with a focus on signal clarity, textural character, and practical usability for sound design and post-production.

This library is well suited for:

industrial and technological atmospheres 

sci-fi and electro-mechanical sound design 

drones, backgrounds, and energy textures

film, games, trailers, and multimedia installations

 All sounds are organized according to the UCS standard and feature clean, consistent metadata. The library is fully Soundminer compatible, ensuring fast browsing and efficient workflow integration.
