Voicebox: Local-first Voice Cloning Studio

TL;DR: Voicebox is an open-source desktop studio for voice cloning and speech synthesis using Qwen3-TTS, offering multi-track editing, on-device models, and Metal-accelerated inference on Apple Silicon.

• Uses Qwen3-TTS for near-instant voice cloning from a few seconds of audio
• Built with Tauri (Rust) and an MLX backend for native Metal acceleration on Apple Silicon
• Desktop-first design with multi-track timeline, audio trimming, and conversation mixing
• Releases available for macOS (Apple Silicon and Intel) and Windows; Linux builds pending
• API-first approach for integrating synthesis into other projects without cloud dependence
