Transcriptor

Transcriptor is a Rust + React app that transcribes WAV audio with Whisper running on the Candle crate.

Stack

• Backend: Rust, actix-web, Candle + candle-transformers Whisper
• Frontend: React (Vite)

Features

• Upload a WAV audio file from the React UI
• Run transcription on the Rust backend using Whisper (tiny.en)
• Download transcription as TXT or DOCX

Run backend

cargo run

Backend starts on http://localhost:8080.

Run frontend

cd frontend
npm install
npm run dev

Frontend starts on http://localhost:5173 and calls http://localhost:8080 by default.

To customize backend URL:

VITE_API_BASE_URL=http://localhost:8080 npm run dev

Notes

• Whisper model files are fetched from Hugging Face on first transcription request and cached locally by hf-hub.
• Current backend expects 16kHz WAV input to match Whisper preprocessing.
