tizerk/ytiz — reverse-engineered prompt

Build me a clean, self hosted web app for downloading audio from SoundCloud, Bandcamp, Twitter, and TikTok without the sketchy popup ad experience those sites usually have.

I want a simple page where someone can paste a link, pick the audio quality from low up to 256 kbps, choose the format as MP3, FLAC, or M4A, and download it quickly. Please include embedded metadata like the track title, artist name, and cover art when possible. It should also let people trim the download to a short clip, up to 5 minutes, before saving it.

Make the interface feel fast and modern, with optional browser notifications and a little sound effect when a download finishes. If there are edge cases or unsupported links, show friendly error messages instead of breaking.

Please wire up whatever frontend and backend are needed so it runs locally with a straightforward setup, and include clear env examples and start instructions. You can look up current docs online if needed.
