Openutau

OpenUTAU is a vocal synthesis editor and neural vocal workstation designed for composing singing voice sequences. It functions as a digital audio workstation for virtual singer composition, featuring a MIDI vocal arranger and a sequencer compatible with the UTAU voicebank standard.

The platform integrates with external neural network synthesis servers to generate high-fidelity singing audio. It provides a phonetic singing controller for mapping lyrics to phonemes and fine-tuning pitch, vibrato, and articulation curves.

The software includes a comprehensive suite of phonetic processing tools for multi-language phonemization, linguistic rule processing, and cross-language transitioning. Sequencing capabilities cover piano roll editing, multisyllabic word mapping, and vocal track management, while tuning tools allow for precise phoneme envelope adjustments and pitch bend modulation.

Extensibility is provided through a plugin system for custom phonetic editing and automated macros.
