Lost Audio is a digital audio company that produces sample packs, preset packs, and production templates for electronic music producers. Operating out of the website lostaud.io, the company was formed by a collective of producers aiming to make studio-quality sounds accessible and royalty-free for everyday creators. Their releases span a wide range of contemporary electronic genres, including tech house, drum & bass, color bass, dubstep, trance and neo-trance, UK garage, hardwave, hybrid trap, jungle, amapiano, and hardstyle.

The catalog is built around themed collections, often produced in collaboration with guest artists. Notable releases include Eon, a Serum preset pack and sample library focused on neo-trance and Y2K-inspired electronic music; Virtual, drawing from trance, 90s house, and jungle; Nature, a Porter Robinson-inspired sample pack; Sugar, conceptualized around Flume-style granular textures, drums, FX, and pads; and UKB2, a UK bass collection inspired by producers like Taiki Nulight and Skrillex. Other contributors and pack creators include CURE97, David Feldman, Teneki, Altered Soul, onumi, YZENIA, Maria Ellis, and Jaydon Lewis.

Lost Audio markets itself toward modern bedroom and professional producers working in bass music, dance, and hybrid electronic styles, with all material licensed 100% royalty-free. Beyond paid releases, the company maintains a free downloads section and a Discord community for producers.

Lost Audio has 18 products cataloged on Equipboard, including Trance - General, EDM, and Bass Music - General.
