Show HN: Music Visualizer Online – Mix audio waves with image/video background (musicvisualizer.online)

I built a free online music visualizer that lets you create unique audio visualizations by combining your music with any background image or video. The tool analyzes audio in real-time to generate synchronized wave patterns that overlay perfectly on your chosen background.

Key features: - Mix audio waves with any background (upload images/videos or use our presets) - Multiple wave styles (classic waves, circular spectrum, particle effects) - Real-time frequency analysis and beat detection - Works directly in browser - no software installation - Supports common audio formats
