alibaba/unified-audio ? reverse-engineered prompt

Build me a clean open source project site and codebase for QuarkAudio, the unified audio system that can handle speech enhancement, speech restoration, speaker extraction, separation, voice conversion, audio editing, audio tokenization, and text to audio demos.

I want a simple homepage that explains the project in plain language, shows the main tasks it supports, and makes it easy to find the paper, demo, and model links. Please make the repo feel ready to share, with a polished landing page, clear README, and example usage for the main audio workflows.

If there’s any setup or missing detail, look up the current docs online and fill in reasonable defaults. Keep it focused on audio processing and generation, and make it easy for someone to understand what each part does and how to try it quickly.
