Unidentified Sound Object is an independent sound effects library publisher with an all global client base. We offer licensing of high-quality commercially usable sound effect libraries for your projects. U.S.O.* was founded in 2011 by Matteo Milani. (*pronounced /ˌjuː.esˈəʊ/ /-ˈoʊ/) With more than 20 years of experience, our services today include complex sound design, composing and mixing for commercials, documentaries & films. As a post-production audio specialist, Matteo still explores creative opportunities both in the studio and in the field, inventing world-class sfx libraries. The packages contain a wide variety of original sources: materials generated through analog and/or digital synthesis, or recorded with unconventional miking techniques. All of the audio files have been loudness-normalized and embedded with metadata for detailed and accurate searches in your software asset management.
