London Atmos

Trailer Music — Homay Schmitz

LABS London Atmos

Taking inspiration from Musique Concrète, Jon Hopkins & Burial, Spitfire engineers Harry and Jess took to the streets of London with a Sennheiser MKH418 to capture the spirit of the capital. From tube doors to city traffic, these field recordings have been warped to give you complete soundscapes — percussion, pads & atmospheric loops, ready to make your own.

Soft Piano

Our Time - Homay Schmitz

LABS Soft Piano

Recorded at Air Edel Studios, this sound has become a favourite of music makers across the globe. The soft tone is achieved by placing a thin strip of felt between the hammers and the strings.


Lights - Oliver Patrice Weder

LABS Strings

Fourteen of London's best string players, recorded at Spitfire HQ by wise-beyond-his-years Harry Wilson. This ensemble was captured using a wide range of microphones including a vintage BBC AXB1. It's awesome.

Hand Bells

Pluviophile — Louis Rugg

LABS Hand Bells

Add a touch of glistening magic to your music. Many years ago, we dotted a selection of hand bells around the Spitfire office, dinging them at any punchline. Hearing their sampling potential, we took them into the Spitfire studio, adding vibrato and ghostly effects.

Pedal Pads

Synaesthesia — Louis Rugg

LABS Pedal Pads

In 2018, Christian fed a Wurlitzer, felt piano and guitar through ethereal effects pedals, including Gamechanger Audio’s Plus pedal, which sustains any sound indefinitely to create a soft pad effect. Discover nine patches of ambient pads, perfect for all your dream sequences.

Music Box

Spieldosen Musik — Oliver Patrice Weder

LABS Music Box

Discover the bewitching sounds of two music boxes. One was made and performed by award-winning composer and artist Hannah Peel, and features on her score for HBO’s Game of Thrones: The Last Watch. She made it by hand printing notations on paper with a hole puncher — the sound of the paper rolling through the box adds a beautiful texture. The other was sampled at Spitfire Studios on top of a piano, for extra resonance.


Pollinators — Louis Rugg

LABS Dulcimer

Two dulcimers, recorded by composer and Spitfire Audio founder, Christian Henson. He sampled a range of playing techniques to capture the versatility of the instrument. Choose hammered for a round, warm tone, fingerpicked or tremolo for a more metallic edge, and discover the spellbinding quality of the mini dulcimer, with glissandi.

Scary Strings

Louis Rugg — Off-Kilter Butterfly

LABS Scary Strings

These haunting string evolutions were the inspiration behind Spitfire’s Evolutions libraries, born out of the need for subtly shifting textures. Performed by a small ensemble of string players, we give you three distinctive presets: Cool, which creates icy overtones; Sustain, for longer notes; and Stretched, for a disturbing, drawn-out effect that will make your hairs stand on end.

Modular Piano

Mute Reformer — Louis Rugg

LABS Modular Piano

In January 2019, Christian Henson made a modular piano. He sampled his upright Schimmel felt piano and Wurlitzer, passing the signal through his modular rig — an array of analogue reverbs, delays, and other goodies — to give you twelve unique, beautifully atmospheric sounds with a slightly industrial edge.

Peel Guitar

Gaia — Louis Rugg

LABS Peel Guitar

Sampled by Christian Henson back in 2006, this classic instrument has been used all over his scores, and despite its simplicity, is a directors' favourite. Created using a Fender Telecaster fed through a 15w vintage tweed amp with a hint of vibrato, tremolo and distortion, we offer you a guitar sound synonymous with British indie music.

Frozen Strings

Of All Man's Appetites — Louis Rugg

LABS Frozen Strings

LABS Frozen Strings was the spark of inspiration that led to the making of one of Spitfire's most renowned libraries — Albion V Tundra. With just six strings players, recorded dry on a cold day in January 2015, Christian Henson set out to create a sound of stark beauty, something that would fit against low, grey skies — the super sul tasto is a haunting highlight.

Synth Pads

And the Robot had a Voice - Louis Rugg

LABS Synth Pads

Recorded in May 2018 by Spitfire engineers Harry Wilson and Harnek Mudhar, LABS Synth Pads was created using Christian Henson’s much-envied synthesiser collection. They fed five vintage synths through reverb, guitar pedals and a selection of outboard gear to create a super celestial sonic universe!


Virus — Oliver Patrice Weder

LABS Choir

In June 2017, we sampled the exceptional Eric Whitacre Singers at Air Studios, London, to create our first ever choir library, curated and conducted by Eric Whitacre. LABS Choir features ever-changing choral samples, created by combining three evolutions from this epic vocal encyclopaedia — the textures weave in and out of each other and evolve constantly as you play, offering you endless inspiration. 


The Armadillo — Louis Rugg

LABS Charango

This charango — an Andean guitar-like instrument — was recorded back in 2006 by Christian Henson on a KM184 mic in his Soho flat, played by his brother Joe. This was the instrument that inspired Christian and Paul to create Spitfire Audio.

Electric Piano

Neutral Planet — Fiifi Mills

LABS Electric Piano

This legendary vintage electric piano is set to become a firm favourite for all. Recorded and engineered in-house by our very own Henry Cornish in April 2018, it has become hugely popular at Spitfire HQ.

Amplified Cello Quartet

Asphyxia — Louis Rugg

LABS Amplified Cello Quartet

LABS Amplified Cello Quartet was recorded by our founder Christian Henson and engineer Harry Wilson in 2017, here at Spitfire HQ. Christian played with the sound during the live recordings using effects pedals, with the celli in one room and the amps in another. The amps were driven incredibly hard, allowing you to turn your strings up to 11!


Kickback — Louis Rugg

LABS Drums

Recorded at Spitfire HQ in 2012 using top-of-the-range mics, these drums showcase the talents of drummer Oliver Waton and engineer Stanley Gabriel. Play and program an awesome piece of kit — ba dum tss!
