xinxin-song is a free, open-source local pipeline for creating an AI vocal cover from an original song and a selected voice model. Its documented process separates vocals and accompaniment with Demucs, converts the vocals through RVC, and mixes the result back with the accompaniment. You can provide already separated vocals and instrumental audio to skip Demucs; UVR5 is suggested for preparing vocals externally. The V1 workflow performs inference for one song at a time and does not train voices. Voice-model training is handled separately in RVC WebUI. The Windows-oriented command line includes pitch shifting, selectable F0 methods, RVC index tuning, denoising choices, and WAV or MP3 export. FFmpeg applies loudness normalization and a limiter during mixing. Each song normally receives an output directory containing intermediate audio, the finished cover, a parameter snapshot, and a run log. Setup requires two Python environments, FFmpeg, RVC assets, and a trained model; the documented RVC setup uses Python 3.12 and CUDA 12.8, with an RTX 5070 Ti as the development target. The code is MIT licensed. The README advises authorization before public sharing and warns against impersonation.
Who it is for
It suits Windows users comfortable with Python environments, RVC assets, and command-line audio processing. Users must handle voice and copyright permissions before sharing covers.
