Discovery Sound is a Japanese sample library label operated by Discovery Firm, Inc., founded in 1990. The company specializes in ethnic and world music sample libraries, focusing on authentic recordings of traditional instruments and vocalists from across Asia and beyond, including Japan, India, Tibet, Thailand, Indonesia, China, Vietnam, and the Republic of Tuva.

Its catalog spans titles such as Discovery Japan, Koto, Shamisen, I Love Tibet, and India Surprise, alongside genre-focused collections covering dance, hip-hop, jazz, R&B, vintage sounds, drums, percussion, and chiptune-style packs like 8 Bit Family II. Recordings typically feature soloists tracked in isolation rather than as ensembles, capturing instruments like shakuhachi, koto, and shamisen in detail. Libraries are delivered in a wide range of formats including ACID, REX2, WAV, Kontakt, Battery, HALion, EXS24, Akai, and Reason (RNS).

The label is aimed at composers, producers, sound designers, and creators working in film, television, video games, and multimedia who need access to traditional and regional sound sources. Its world music titles in particular have been reviewed in publications such as Sound on Sound.

Discovery Sound has 17 products cataloged on Equipboard, including Asia, World - General, and Synths.
