8Dio is a developer of deep-sampled virtual instruments and sample libraries for Native Instruments Kontakt, founded in 2011 by composer Troels Folmann and Broadway producer Tawnia Knox. Based in Santa Monica, California, the company grew out of Folmann's earlier production-audio venture 8Dawn and built its reputation on large-scale, cinematic sampling projects aimed at film, television, and game composers.

The catalog focuses on orchestral, choral, percussion, and hybrid scoring tools, including the Majestica symphonic orchestra, large-format choir libraries, taiko and epic percussion ensembles, multi-player cello sections, and a line of deep-sampled pianos. 8Dio also publishes EDM, guitar, and sound design libraries, alongside a free community-built collection called Free Home.

Folmann's background as a BAFTA-winning composer and Ph.D. in music technology informs the company's emphasis on deep-sampling techniques, layered articulations, and specialized controllers inside Kontakt. Their instruments are widely used by composers working on film scores, trailers, video games, and television productions.

8Dio has 72 products cataloged on Equipboard, including Kontakt Instrument, Strings, and Synth Plugins. Their gear is featured by 7 artists, with the strongest followings in Stage & Screen, Electronic, and Orchestra. Notable users include Paul Haslinger, Hiroyuki Sawano, and Trevor Morris. Most 8Dio products sit on the budget-friendly end of the spectrum.
