In their own words
NEUTRINO
NEUTRINO is an AI singing voice generator that synthesizes vocals from sheet music. Users provide lyrics and melody; the system estimates vocal timing, pitch, voice quality, and breathiness, then a vocoder produces the singing. The project says its models draw vocal traits from recordings made with performers' permission or audio released by public institutions, rather than existing pretrained models. The FAQ describes Muon voice retakes and adjustable quality and processing speed, with advanced, standard, and elements modes. Advanced and standard output is 48 kHz, 16-bit mono WAV; elements output is 24 kHz, 16-bit mono WAV. It is available for Linux, macOS, web, and Windows. Users download the software and add a voice library. NEUTRINO is free for general music and audio production, but embedding the software or using generated audio inside an application requires separate permission. Character-specific terms also apply to ordinary audio-file uses and vary by character and asset type. Users cannot currently create their own voice libraries with a released framework, according to the FAQ.
