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 3 products cataloged on Equipboard, including DAW Software, Pitch Shifter Plugins, and Virtual Instrument.
