Gharmonize is an open-source, Node.js-based media processing tool that works alongside yt-dlp and FFmpeg to download and convert audio or video from YouTube, YouTube Music, and Spotify (via metadata matching). It also supports processing external audio and video files beyond YouTube/Spotify URLs, allowing users to convert or re-encode their own media with the same advanced codec engine.
