0107_44s.mp4

A wrapper for Meta's SAM Audio Editor that handles audio files of any length (Meta's demo has a 29-second limit).

Upload an MP3/WAV/M4A and edit it with natural language prompts like "remove vocals" or "isolate the drums". Audio >29s is automatically split into chunks, processed in parallel, and stitched back together.

Setup & Run

Run the setup script (handles everything automatically):

./setup.sh

The script will:

• Install ffmpeg (if not present)
• Install Chrome (if not present)
• Create a virtual environment (uses uv if available for faster installs)
• Install all Python dependencies
• Install Playwright and its dependencies
• Install all frontend dependencies (uses bun if available)
• Optionally start both backend (port 8000) and frontend (port 3000)

Then open http://localhost:3000

Notes

Built on top of Meta's SAM (Segment Anything Model) audio demo.
