Realivox is a line of vocal sample libraries developed by Realitone, a virtual instrument company run by producer and composer Mike Greene. Built for Native Instruments' Kontakt, the Realivox products focus on capturing studio-recorded female vocalists for use in pop production, film scoring, and electronic music.

The range includes Realivox Ladies, which features five Los Angeles session singers (Cheryl, Teresa, Patty, Julie, and Toni) recorded across multiple articulations for lead and backing vocal arrangements; Realivox Ladies Lite, a stripped-down version focused on background "oohs" and "ahs"; and Realivox Blue, a deeper solo-voice library with more than 12,000 samples and a word-builder interface that uses six vowels and 23 consonants to construct phrases. The libraries are built around realistic phrasing and round-robin sampling rather than synthesized vocals.

Realitone's broader catalog includes other sampled instruments such as Sunset Strings, Sunset Choir, RealiBanjo, RealiDrums, and Hip Hop Creator, but the Realivox name specifically refers to the vocal-focused libraries that established the company's reputation in the Kontakt sample library market.

Realivox has 2 products cataloged on Equipboard, including Kontakt Instrument.
