At LeafAudio, we design and handcraft high-quality tools specifically designed for field recording. Our focus is on devices that capture sound through physical body sound vibration rather than airborne waves. Offering you a different and often overlooked dimension of sonic exploration. From contact microphones to geophones and precision amplifiers, our tools open up entirely new ways to experience and record the world around you.
With our Contact Microphone , any object or surface can become a unique sound source. Unlike conventional microphones that rely on air pressure to record sound, contact mics pick up vibrations directly from solid materials. This allows you to uncover the hidden acoustic character of everyday objects. Metal railings, wooden tables or glass panes can become instruments. It's an inspiring way to create experimental textures or rhythmic elements that would be impossible to achieve with standard microphones.
To support and enhance this approach, we offer the Field Amp , a dedicated preamp designed to amplify the signals from contact microphones with clarity, detail, and extremely low noise. Whether you're listening to the faint creak of decaying wood, the soft crawling of insects, or the flow of water in trees, the Field Amp ensures every nuance is preserved. It’s built to meet the high demands of field recordists, sound designers, and experimental musicians alike.
For those interested in deep, sub-sonic frequencies, our Geophone is an essential tool. Unlike contact microphones, which are more broadband in character, the geophone specializes in capturing low-end vibrations, starting from around 15 Hz. This makes it perfect for recording powerful, physical sounds such as underground movements, industrial machines, or distant rumbles. When used alongside conventional microphones, the geophone adds a cinematic depth and haptic force to your recordings, providing a seismic sense of space and presence.
Adapter Cable 3,5mm-to-6,3mm
available
Slimline adapter cable from 3,5 mm (1/8") to 6,3 mm (1/4"). Like the shorter ones it is made of very flexible TPE material with a nice soft and rubbery feel. They are specially made for us. The connectors are extremely slim, what's good when you use very densely packed modules or audio interfaces. Simplicity rules: this series of cables is monochromatic black & white, as we wanted to make it look clean but organized when mixed on your system.It's also available in 200 cm length as a normal patch cable plus also in shorter lengths between 7 cm and 60 cm.Facts:• Side 1: 3,5 mm (1/8")• Side 2: 6,3 mm (1/4")• 200 cm (black)• Pack of 1 piece

LeafAudio - Contact Microphone 3,5mm (1/8") Connector
available
This is the new 2025 Contact Microphone version - better than ever. This is the 3,5mm (1/8") jack connector version. With a contact microphone, any surface or object becomes a canvas for sonic exploration. Unlike traditional recording methods that capture sound waves traveling through air, contact microphones pick up vibrations directly from materials — allowing you to "listen" to objects, plants, or even soil from the inside out. This unique perspective unlocks a world of intriguing and sometimes abstract sounds, making it an essential tool for experimental recording and sound design. The 2025 edition of LeafAudio’s popular contact microphone has been completely re-engineered for maximum flexibility and features full electrical shielding for optimal performance.This upgraded model comes in a set with a durable neoprene zip-bag, ensuring safe transport while providing space for all included accessories. Thanks to its universal clamp mechanism and strong rubber bands, it can be mounted on almost any surface. Additionally, the newly developed probe mechanism — created in collaboration with sound designer Robert Dudzic — lets you capture sounds even from inside objects, soil, and more, expanding the creative possibilities even further.Equipped with a high-quality 2m (6.5ft) SC-Onyx Tynee cable by Sommer Cable, the microphone is available in two versions: one with a 3.5mm (1/8") Amphenol connector and another with a 6.3mm (1/4") Hicon connector. Includes:• Contact microphone• Neoprene zip-bag• Universal holder• Probe mechanism• 2 rubber bands• Allen key

LeafAudio - Field Amp
sold out at the moment
Field Amp is LeafAudio's solution for the world of body sound transmission: recording the world with contact microphones. It provides high-gain, noise-free amplification and impedance conversion to ensure the best possible sound quality from your contact mics.After releasing our Microphonic Soundbox, we quickly realized we’d hit a sweet spot. Many sound designers praised its clean, noise-free amplification - even if they didn’t need the Soundbox itself. So we listened and created a standalone solution: the Field Amp. If you want the Soundbox amp without the box, the Field Amp is your new best friend. Perfect for studio work, field recording, sound installations, and creative sound design of all kinds.Quality amplification & power management circuitry. No noise or beeping can be heard or seen in the spectrum, not even above the hearing range, which would come into focus later during sound manipulation processes. You can record with high sampling rates, transpose the audio by a lot and enjoy your pure sound. Just the clear, pristine audio you want to capture with your contact microphones.Optimised for travelling. The small unit is fully portable, light, offers many mounting possibilities. A professional case is included, which also can carry your contact mics, batteries and cables.Body sound transmission vs. airborne sound. We’re used to hearing the world the way our ears do—through air. Sound travels through the air before reaching our eardrums or a microphone. But with contact microphones, you change that perspective. Instead of hearing the surface of materials, you hear from within them. This shift opens up a powerful trick for sound design. It reveals a hidden world of textures and tones that are normally out of reach. Give it a try—there’s an entire universe of sound waiting to be discovered.Field Amp is optimised for Hi-Z signals of contact microphones. It also acts as an impedance converter with a powerful output signal. No loss of signal quality when you keep the wiring short between microphones and the input. The output is a strong signal and you don't have to worry about a few meters of cable.We recommend using the shielded contact microphones by LeafAudio. Generally you can try contact mics with our pre-amp, hydrophones, or guitar pickups. We offer separate adapters for both input and output to ensure compatibility with all your devices.Features:• Low-Noise pre-amp for contact mics, geophones etc.• Case included• 9V DC power supply or battery• USB-C to barrel connector adapter cable included• Up to ~50x adjustable gain• 1 mono input• 2 mono outputs (one -12 dB)• All connections 3.5 mm (1/8") mono jack• Input impedance: 3,3M Ohm• Output impedance: 1k Ohm• 12 x 12 x 3.4 cm• 410 g (incl. case & USB-C to barrel cable)• 1/4"-UNC mount on top and bottom for camera tripods etc.
