Sounds from a Transit System on Pause.
Underground Ambiences and Mechanical Atmospheres for Cinematic and Abstract Soundscapes.
The Still Line is a 139-minute sound effects library capturing the rare stillness and quiet pulse of an underground rail network paused in time. Recorded during a period of minimal traffic, as public life slowly returned after lockdowns, it spans resonant tunnels, hushed platforms, and moving trains, with subtle human presence woven throughout—footsteps, luggage wheels, and distant voices—adding life without disrupting the pervasive stillness. These recordings offer rich ambiences and precise mechanical textures, perfect for grounding a scene in reality, providing unique sonic textures, or reimagining it for something entirely new.
Step into an underground transit system where empty platforms, echoing tunnels, the mechanical heartbeat of infrastructure, and sparse human touches all coexist to create a cinematic soundscape.
This mini-library offers over two hours of recordings from quiet platforms, long tunnels, ticket halls, train interiors, and the subtle machinery that sustains the network. Freed from the usual crowd noise, every detail emerges: the tonal hum of escalators, the metallic sigh of air brakes, distant trains rolling through silent tunnels, and the layered resonance of vast, reflective chambers.
What’s Inside
Whether you’re building a dystopian future, crafting cinematic tension, or repurposing urban textures for abstract sound design, The Still Line offers a unique palette grounded in reality yet open to transformation.
A collection of rending, snapping, and striking bamboo SFX + some extra added goodies.
This library consists of two different sessions where we dropped cars from a crane onto other cars and onto the ground. The first session contains lots of windows being smashed and sounds of car body debris from two hanging cars scratching against each other. During this session, microphones were positioned inside the vehicles as they were dropped from the crane as well. The left side of the onboard recorder comes and goes, but we decided to leave it in the library since it has some very nice bits in it.
Smashing plates, bowls, mugs and vases!
We’ve all needed sounds of smashing ceramics and glass, but you can’t always convince someone to let you smash things in their basement!
So I’ve done that part for you!
Variety of smash sounds recorded and exported in 24 / 192Khz perfect for extra impact in any project, whether your game character is smashing pots, or you have an angry character in your film throwing plates at someone!
• In Rock Creatures, get a visceral collection of guttural and grating vocalizations from the volcanic rocks of the Davis Mountains. Scrape rhyolite with intense pressure and hear guttural screeches with vigorous, physical energy. Hear the thick weight of boulders growling and frenetic stutters of rocks performed to sound like animals. Hear textured squeaks of small stones sliding. Hear rocks rich in titanium clattering to create otherworldly harmonics perfect for creature sound design.
• This library offers you an extensive collection of rocks painstakingly performed to bring these inanimate objects to life and transform them into intensely vocal creatures.
2% FOR THE ENVIRONMENT:
• Two percent of the price of this library is donated to an environmental cause, as an “artist royalty” for the planet!
Scratches is a comprehensive library of 700 recordings of scraping, cutting, scuffing, peeling and rubbing sounds. This high-quality collection of versatile sounds will make your skin crawl and hair stand on end.
The idea behind this project was to gather a wide assortment of objects like saws, scissors and chalks, and to record their acoustic interaction with surfaces such as wood, glass, metal, concrete and gravel. We even came to vandalize a few musical instruments (snare drums, oriental percussions, cymbals and more) with hammers and knives in order to capture weird noises and unique musical qualities.

Vibration is 40 minutes/676 MB of vibrating, rattling and resonating metal and plastic panels in 96 separate files – recorded in 24bit/96kHz using contact microphones. All files are UCS-compliant.
This is a collection of sounds that rattle, clatter, vibrate, buzz, hum and oscillate. Think huge cargo vehicles, passenger ferries or mechanical installations with loose metal panels, resonating generators and such. The vibrating was done with a 100 watt tactile transducer (like a bass speaker with no cone) hooked up to an amplifier, and getting it’s signal from a modular synth. Frequencies from LFO’s and VCO’s were mixed, to get interesting vibrations in both sub-audio and audio range.
Holding the transducer by hand allowed me to move it around and find the sweet spots on the various objects (a steel filing cabinet, a steel suitcase and a spring reverb tank come to mind). Depending on the amplitude of the input signal, different sounds would emerge from the same waveforms. Now and again, the transducer would get too hot to handle, and on one or two occasions, the thermo-relay on the amp would kick in. Excitement in the studio!
With A Sound Effect, Asbjoern has created a web site where our international community can browse, learn, and share the vast fruits of our labors. Together we are accelerating the very real potential power of sound design as a recognized art form.
A Sound Effect is an excellent resource for us to keep our animated films sounding unique and exciting.
A Sound Effect is a great asset to have discovered.
We found the site very easy to navigate, purchasing and downloads were effortless and the effects themselves are awesome! Asbjoern has done us all a great service.
We’ll definitely be back!
There are many great independent sound effect libraries available these days. The main problem with having so many, is keeping track of them!
A Sound Effect is a great hub, and is one of the first places I visit to look for sounds by category or genre. I started coming here to see if I could find libraries that I knew I had heard, but forgot WHERE I had heard them.
And in the process discovered libraries I never would have found otherwise. Great work! Keep it up!
We're always looking for new sounds to mangle, so when A Sound Effect had a holiday sale, I tried them out.
The purchase experience is really smooth and quick, and delivery is almost instant.
I'll definitely come back to them again in the future!
A Sound Effect is a wonderful resource for indie sound effects libraries. On top of that, it has some of the finest sound design, film and game audio interviews!
I often need very specific types of sounds so I've become a big supporter of independent recorders.
Until now I've always had to go to their individual websites. Now I can find them all in one place.
And, Asbjoern is great to work with!
A Sound Effect is a well curated boutique sound effects shop and a great place to find industry interviews and learning resources.
