RVC WebUI review
A feature-rich local toolkit for training voice models and converting audio.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
RVC WebUI is an open-source framework for training and running retrieval-based voice-conversion models. It is aimed at people who want local control over model training, real-time voice changing, or offline audio conversion rather than a simple preset-based changer. The project includes a WebUI for training and offline inference alongside a separate real-time voice-changing GUI, with support for single- and multi-speaker models.
Its feature set reaches beyond basic timbre conversion: users can adjust pitch and pitch extraction, apply Top-1 retrieval to reduce tone leakage, fuse models to change timbre, and separate vocals and instrumentals through PyMSS/MSST models. Batch processing covers files and directories, and exports include WAV, FLAC, MP3, and M4A. The surrounding tools include FFmpeg, Gradio, RMVPE, and HuBERT. That makes RVC WebUI a fit for workflows involving model training and audio-file processing, as well as live conversion. Users seeking character presets should note that the project documents user-provided and multi-speaker models instead.
The project targets local installation on Windows and Ubuntu, with hardware-specific dependencies for CPU, AMD, Intel, and NVIDIA systems. Buyers should account for that setup and hardware variation when considering it; it is not presented as a broadly hosted or cross-platform service. Real-time input and output audio devices are supported, but a virtual-microphone feature is not verified, so users who need direct virtual-mic routing should consider a tool that explicitly offers it. Choose RVC WebUI for configurable, open-source training and conversion; look elsewhere for a simpler preset experience or verified virtual-microphone support.
RVC WebUI pros and cons
- Where it wins

- Trains and fuses voice models, with pitch and retrieval controls
- Exports audio as WAV, FLAC, MP3, or M4A
- Where it doesn't
- Targets local installation on Windows and Ubuntu
- Hardware-specific dependencies vary across CPU and GPU systems
- No verified virtual-microphone feature for routing changed audio
