Dreamtonics is a Tokyo-based audio software developer founded in 2019 by engineer Kanru Hua, specializing in AI-driven singing voice synthesis. The company's flagship product is Synthesizer V, a vocal synthesis platform built around neural network models trained on recordings from real, licensed singers. Synthesizer V Studio 2 Pro, the latest iteration, functions as a standalone editor and plugin for producing lead vocals, harmonies, and choral arrangements with fine-grained control over pitch, pronunciation, timing, and expressive delivery.

The Synthesizer V ecosystem spans more than 75 voice databases covering English, Japanese, Mandarin, Cantonese, Spanish, and other languages, released both by Dreamtonics and by third-party partners such as AHS, Eclipsed Sounds, and Quadimension. Dreamtonics also produces dedicated choir voice collections and sells commercial-use licenses, which has made the software a common tool in songwriting demos, indie releases, game and anime soundtracks, and vocaloid-adjacent music communities.

Often compared to earlier vocal synthesis systems like Vocaloid, UTAU, and CeVIO, Dreamtonics' software is known in the vocal synthesis community for its naturalness of output, cross-lingual voice capabilities, and a relatively open model that welcomes third-party voice developers. The company operates an online store at store.dreamtonics.com and maintains an official community forum.

Dreamtonics has 50 products cataloged on Equipboard, including Expansion Packs, DAW Software, and Pitch Shifter Plugins.
