| # RVC-Realtime-GUI |
| **A self-contained Windows desktop application for low-latency, real-time RVC voice conversion.** |
|
|
| This release is a focused real-time inference client derived from |
| [RVC-WebUI](https://github.com/RVC-Project/Retrieval-based-Voice-Conversion-WebUI). |
| It is designed for live microphone use, virtual audio routing, and audio-file |
| playback through a compact CustomTkinter interface. |
|
|
| Source code: [niel-blue/RVC-Realtime-GUI](https://github.com/niel-blue/RVC-Realtime-GUI) |
|
|
| ## What's new in this release |
|
|
| **This build includes the real-time inference performance updates introduced |
| after 2026-07-18.** |
|
|
| - CUDA Graph warm-up for lower per-chunk inference overhead after startup |
| - Updated real-time inference path and input/output noise-reduction fixes |
| - CUDA 12.8 runtime for current NVIDIA GPUs, including Blackwell-compatible |
| environments |
| - Native ASIO buffer preservation: starts ASIO with the driver's preferred |
| buffer size instead of allowing the high-latency default to select a larger |
| buffer |
|
|
| ## Download |
|
|
| Open the **Files and versions** tab and download the archive that matches your |
| NVIDIA GPU. |
|
|
| | Package | Status | Use it when | |
| | --- | --- | --- | |
| | `RVC-Realtime-GUI_cu128_260729.7z` | Current standard build | You use a current NVIDIA GPU, including Blackwell-compatible environments. | |
| | `RVC-Realtime-GUI_cu118_260729.7z` | Legacy build (available) | You use an older NVIDIA GPU that cannot use the CUDA 12.8 build. | |
|
|
| Extract the archive to a short local path, for example `C:\RVC-Realtime-GUI`. |
| Do not run it from inside the archive. |
|
|
| ## Quick start |
|
|
| 1. Extract the downloaded archive. |
| 2. Open the `models` folder. |
| 3. Start `RVC-Realtime-GUI-CUDA128.bat` for the CUDA 12.8 package, or |
| `RVC-Realtime-GUI-CUDA118.bat` for the CUDA 11.8 package. |
| 4. Choose a model, audio devices, and press **Start**. |
|
|
| The package already contains its Python runtime, PyTorch/CUDA stack, FFmpeg, |
| and inference assets. No separate Python, CUDA Toolkit, FFmpeg, or RVC-WebUI |
| installation is required. |
|
|
| ## Adding models |
|
|
| Create one folder per model under `models`: |
|
|
| ```text |
| models/ |
| MyVoice/ |
| MyVoice.pth |
| added_MyVoice.index |
| preview.png |
| ``` |
|
|
| - The **folder name** is shown as the model name in the app. |
| - Put the model `.pth` and its `added_*.index` file in the same folder. |
| - An optional `.png`, `.jpg`, or `.jpeg` image in that folder is shown as the |
| model preview. |
|
|
| Restart the app or use **Reload** after adding or changing a model. |
|
|
| ## Features |
|
|
| - Real-time RVC inference with CUDA Graph warm-up |
| - WASAPI and native ASIO audio-device routing |
| - Separate input, output, and monitor devices |
| - Model gallery with previews and model-specific general settings |
| - Audio-file input through bundled FFmpeg |
| - WAV recording: separate input/output files, mixed recording, or split L/R |
| - Japanese and English interface |
| - Runtime log viewer, log export, and recording status display |
|
|
| ## Notes |
|
|
| - This release is for **Windows and NVIDIA GPUs**. |
| - Start with conservative chunk and buffer settings, then lower latency only |
| after confirming stable audio on your device chain. |
| - Native ASIO uses the driver's preferred hardware buffer size; RVC processing |
| chunk length is kept separate from that setting. |
| - ASIO and WASAPI can differ substantially by driver and virtual-audio setup. |
| - RVC models are not interchangeable with this package unless they are valid |
| RVC `.pth` models. Use only voices and audio material you are authorized to |
| use. |
