The record

Product: OpenVoiceChanger is a self-hosted web application for real-time AI voice conversion using ONNX or RVC models.
Live conversion: It streams microphone audio over WebSockets and also supports model-free DSP voice effects.
Voice controls: The studio includes pitch and formant shifting, 16 F0 methods, 12 DSP effects, and 16 built-in voice presets.
Custom presets: Users can save custom presets containing the complete Voice Lab settings.
File conversion: The offline converter accepts WAV, MP3, FLAC, OGG, and M4A files and renders WAV output; the configured maximum is 600 seconds.
Model formats: The app supports ONNX models and RVC PyTorch .pth or .pt models, with RVC requiring a HuBERT content encoder.
API: The backend exposes HTTP endpoints for health, models, presets, and conversion, plus a WebSocket endpoint for live audio.
Integrations: The README documents ONNX Runtime, PyTorch, RVC, and GitHub Releases for updates; it does not list third-party conferencing integrations.
Security: The backend binds to localhost by default, checks browser origins for HTTP and WebSocket requests, and loads RVC checkpoints in safe weights-only mode by default.
Local storage: Recorded takes are stored in browser IndexedDB on the same origin and may be cleared or evicted by the browser.
Updates: The app checks public GitHub Releases, but installation requires a user action through the managed launcher and a clean main branch.
Platforms: The quick-start instructions target Windows PowerShell; the README says other platforms use manual setup and documents POSIX-shell or WSL Makefile commands.
License: The repository identifies its license as MIT.
Requirements: The listed requirements include Python 3.10 or later, Node.js 20.19 or later, and npm.
