Physics-based visualizer with OS-level pause suspension, but yt-dlp YouTube extraction isn't novel.

Strengths

•Physics-driven 30+ FPS visualizer with gravity peak-drop and symmetry is technically impressive
•OS-level process suspension for stutter-free pause without buffering cuts
•Textual-based TUI feels modern and responsive with proper keyboard navigation

Weaknesses

•Requires YouTube API key setup and external ffmpeg dependency adds friction to installation
•YouTube Music functionality directly competes with established clients (Spotify CLI, ncspot) with no differentiation

Post Description

Most CLI players have very rudimentary visualizations, so I focused on creating a "Quantum Spectrum Analyzer"—a high-frame-rate, physics-driven rainbow visualizer that uses gravity-based peak falling and mirrored symmetry.

Under the hood, it manages a pool of ffplay instances and uses OS-level process suspension (via ctypes on Windows and signal on POSIX) to provide an "instant-off" pause experience without cutting the audio buffer mid-stream.
