Machine Emanation is a contact microphone and drone sound effects library focused on machines.
This collection contains multiple recordings and designed drones sourced from band saw to ceiling fan; table saw to dishwasher; thickness planer to paper shredder; bench grinder to refrigerator. Machines were recorded turning on and off, running, and at any available speeds.
Machine Emanation is built for sound design. Recorded at 192 kHz with Barcus Berry 4000 and JrF C-Series contact microphones; these high resolution recordings make for great unique sound design source material. High sample rates mean far more possibilities for stretching, bending, and manipulating these SFX into your next creation.
Also included are drones designed from each machine. Power tools and appliances are re-imagined as dark rumbling drones and unique atmospheres. A small glimpse of what can be created with Machine Emanation.
What’s included?
- Rumbling & Grinding Power Tools
- Resonant & Pulsing Appliances
- Airy & Dark Designed Drones

Ultrasonic Content
Like every other sound design library from Collected Transients, Machine Emanation is recorded at 192kHz/24bit so all of the delectable ultrasonic content is properly captured. “But I’m not a dog!” you say, “I only hear to a mere 20,000 Hz.”
Fret not, Sound Designer, the ultrasonic content in these collections is captured to allow you to massively pitch-shift and process the sounds while retaining fidelity and revealing elements you couldn’t perceive before. Don’t take our word for it. Listen to demos and learn more here!

Thorough UCS Metadata
Machine Emanation offers thorough UCS compliant metadata that works across all popular audio database software. Each file is embedded with exhaustive information about the recording. Aside from the usual ‘description’, many other fields are available that provide useful tidbits like recording notes, microphone information, category, and sub-category. All sound effects also come embedded with an image showing exactly what was being recorded.

Collected Transients is definitely one of my goto producers for highly detailed libraries for my sound design work. Incredible libraries like rOtation, thermal flux, combustion and machine emanation provide sounds you can’t even imagine and are absolutely perfect for bending and twisting into all kinds of sound design possibilities. And for all of the subtlety, energy and eventual destruction of an urban environment look no further than diffuse city, we are the people, along with implosion. The outstanding quality within every Collected Transients library makes them an indispensable part of my toolkit.

It goes without saying that the quality is very high. Machine Emanation has been fantastic for my techno music. I have used some of the machines for drones and atmospheres pretty much as is or with side chaining. Just what I need for those dark tracks. I also use them in some of my horror type scoring too. But a secret weapon for my artist work 😉
