The story of Soundiron
Soundiron was founded in 2011 in the United States by Mike Peaslee and Christopher Marshall. Their vision was clear: capture the sound of instruments most studios don't own, from prepared pianos to tribal bells, including full choirs recorded in exceptional acoustics. Unlike the industry giants that favour mass catalogues, Soundiron chose the path of sound craftsmanship. Each library is the result of meticulous collection work, often centred on rare historic or ethnic instruments.
Very quickly, the brand made a name for itself among film and video game composers. Its Olympus series (symphonic choir), its solo voice libraries (Voices of Rage, Voices of the Wind) and its world instrument collections set a quality standard. Today, Soundiron continues to innovate with collections such as Hyperion Strings, the Hopkin Instrumentarium and Basse Machina, while staying true to its artisanal approach.

The Soundiron library ranges
Orchestral and strings
The Soundiron orchestral range includes the Hyperion Strings Micro series, Hyperion Strings Solo Violins and Hyperion Brass Micro. These libraries offer detailed string and brass sections, with multiple articulations, dynamic layers and a realistic rendering for orchestral music. The Ensemble version completes the offer for rich, powerful arrangements.
Voices and choirs
It's in the vocal field that Soundiron particularly excels. The Olympus Choir Micro library offers a complete symphonic choir, while Requiem Symphonique and Mercury (boys' choir) cover specific needs. Solo voices are also well represented with Voices of Rage, Voices of Rapture and the Voices of Gaia series. The Voices of the Wind (Audrey, Connie, Kimba) offer expressive female voices for narrative compositions.
World music and rare instruments
Soundiron is renowned for its collection of world instruments. The Ancient Greek Winds library recreates the wind instruments of Greek antiquity, while Didgeridoos captures the sound of the famous Australian instrument. The Hopkin Instrumentarium series offers unique experimental instruments: The U, Boites Rumba, Rattletines, Lames Métalliques and Cordophones.
Synthesizers and vintage
For fans of electronic and vintage sounds, Soundiron offers Alpha Organ, a virtual organ with warm timbres, and Basse Machina, a library of powerful synthetic basses. These virtual instruments are equally suited to electronic production and cinematic sound design.
Percussion
Percussion is a pillar of the Soundiron catalogue. Apocalypse Percussion Micro offers an epic cinematic percussion kit, while Shaker and Panacée Percussions Accordées cover more specific needs. The Rythmique Odyssée V2 and Rythmes Moteurs offer ready-to-use rhythmic loops.
Pianos and keyboards
Soundiron's Emotional Piano has become a classic for composers looking for a piano with an intimate, emotional character. Recorded with a close microphone, it offers a warm sound perfect for ballads, film themes and ambient compositions.
