What is KohiRVC?

KohiRVC is a real-time voice conversion app that reimplements the open-source AI voice changer "RVC" as a native C++ application, without Python.

• Use your existing RVC v2 models directly. Just import your models (.pth) to use them.

• Lightweight and quick to start. Its native design, with no dependence on Python, keeps startup waits and memory usage low for comfortable use.

• Designed specifically for real-time conversion. Along with low-latency, stable voice conversion, it aims for an intuitive experience with a simple, easy-to-read UI.

Ideal for changing your voice in real time while you talk, such as in in-game voice chat and game streaming.

Features

• Standard-format RVC v2 models: Supports the standard RVC v2 format (with pitch (F0), 32kHz / 40kHz / 48kHz). Load your existing models (.pth) directly. Index files (.index) are also supported.

• Fast startup and lightweight operation: Its native C++ implementation keeps startup time and memory usage low. Designed with use alongside games in mind.

• Real-time automatic chunk adjustment: Dynamically adjusts the chunk length used for audio processing according to the GPU load during conversion. Even when GPU load changes in games and similar situations, it adjusts automatically to keep voice conversion low-latency and stable.

• ASIO® and low-latency WASAPI: Supports ASIO input and output and low-latency WASAPI. Set up input and output to suit your audio devices and environment.

• Pitch and formant: Adjust the pitch and tone of the voice. Settings are saved for each model, and switching models automatically uses that model's settings.

• AI noise reduction: Reduces noise in the microphone input. Turn it on or off as needed.

• Simple, easy-to-read UI: A clean layout that keeps everyday functions within easy reach, with detailed settings available when you need them. Stream mode shows a small window, so you can check the status and start or stop conversion without getting in the way of your game.

ASIO is a trademark of Steinberg Media Technologies GmbH, registered in Europe and other countries.

Privacy

All voice conversion takes place on your own PC. The developer does not collect your microphone audio, converted audio or imported voice models. KohiRVC has no telemetry of its own.

Imported voice models are stored on your PC.

For details, see the privacy policy included with the product.

Before you buy

Please check the following requirements and notes before purchasing.

• Operating system: Windows 11 (64-bit) only. Other operating systems are not supported.

• Steam sign-in: Starting KohiRVC requires signing in to the Steam client.

• GPU: Requires an NVIDIA GeForce RTX 30 series or newer GPU (6 GB VRAM or more) and an NVIDIA driver that supports CUDA 13. AMD or Intel GPUs and CPU-only operation are not supported.

• No voice models are included: Please prepare your own voice models. Standard-format RVC v2 models (with pitch (F0), 32kHz / 40kHz / 48kHz) as .pth files are supported.

• A virtual audio device is required: To send the converted voice to voice chat, streaming or other applications, you need to install a virtual audio device such as VB-Audio Virtual Cable separately.

• Using ASIO: Using ASIO requires a compatible audio device and driver.

• Performance and latency: Actual performance and latency depend on your GPU, audio device, drivers, the voice model used, the load from other applications and so on.

• Rights to voice models: Check the terms of use of your voice models and respect the rights of the voice owners and model creators. Impersonating others or any use that infringes their rights is prohibited.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Some artwork for the store page and the app was created with the help of AI tools. While running, KohiRVC uses an RVC voice conversion model to convert your own microphone audio into another voice, entirely on your PC. No voice models are included.

Name of AI model included with the game: RVC (Retrieval-based Voice Conversion) v2. Voice models are imported by the user; none are included with KohiRVC.
