What vc-rs is

vc-rs is a free Windows voice changer that converts microphone input in real time or processes WAV files with ONNX-format RVC models. It offers a standalone graphical interface, a bundled command-line tool, and a VST3 plugin for digital audio workstations. The GUI provides live gain and pitch controls, audio-device selection, diagnostics, and optional input denoisers. Voice models are not included, but supported RVC v2 F0 PTH models can be converted to ONNX, while the GUI can download ContentVec and RMVPE support models. The CLI handles batch WAV conversion, scripting, model inspection, diagnostics, and Windows ML execution-provider settings. In a DAW, the VST3 plugin supports pitch and gain automation and saves model paths and settings per project or preset. Windows packages include Windows ML and native TensorRT backends, with DirectML plus experimental MIGraphX and OpenVINO paths. Packages target Windows x64. Windows ML requires Windows App SDK Runtime 2.x; TensorRT requires an up-to-date NVIDIA driver. MIGraphX and OpenVINO NPU use are unverified, and overload can cause audio drops or silence.

Who it suits

It suits Windows users converting voices for standalone work, batch processing, singing, or streaming in a DAW. Users need to supply models and meet the package-specific runtime or driver requirements.

What it does well

  • Real-time microphone conversion
  • Standalone GUI, CLI, and VST3
  • Live pitch and gain controls
  • Batch WAV conversion and scripting
  • Project-level VST3 settings

What to know first

  • Voice models are not included
  • Windows x64 packages only
  • Some processing paths are unverified
  • Unsigned binaries may trigger warnings

Verdict

vc-rs combines real-time voice changing, file conversion, command-line workflows, and DAW integration in a free Windows package. Its setup depends on external models and, for some backends, specific runtimes or drivers, while overload may produce drops or silence.
