Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

woys is a Linux-native voice changer for people who want real-time microphone conversion through RVC models. It uses ONNX Runtime CUDA for inference and PipeWire for audio input and output, then exposes the converted signal as a selectable virtual microphone. That makes it suitable for solo Linux users running PipeWire-aware applications such as Discord, particularly those comfortable managing terminal tools and local model files.

Its standout capability is the combination of real-time conversion, model switching, and PipeWire routing in one self-hosted workflow. Users can download and switch RVC ONNX voice models, convert compatible RVC .pth checkpoints to ONNX, and optionally add RNNoise post-processing. The virtual microphone source lets applications consume the converted audio without requiring a separate hosted service. The design is focused rather than broad: it targets Linux audio setups and RVC workflows instead of offering a cross-platform desktop interface.

woys is free to access through its public installation path, with no paid tiers described. The trade-off is hardware and setup specificity: the stated requirements call for PipeWire, a supported NVIDIA GPU such as an RTX 2070 or better, and no CPU fallback. Operation centers on command-line controls and a terminal UI, while support is community-based. The project is not open source, with original code described as proprietary despite including MIT-licensed upstream-derived code. Choose woys if Linux, CUDA hardware, and terminal operation fit your workflow; choose another voice changer if you need Windows or macOS support, CPU operation, or a conventional graphical setup.

woys pros and cons

  • Where it wins
    • Real-time RVC conversion with ONNX Runtime CUDA inference
    • PipeWire-native routing with a selectable virtual microphone
    • Switches RVC ONNX models and converts compatible .pth checkpoints
  • Where it doesn't
    • Linux-only, with no Windows or macOS support
    • Requires a supported NVIDIA GPU; there is no CPU fallback
    • Terminal UI and community support may challenge newcomers
