I'll create a minimalistic and futuristic music visualizer inspired by Kraftwerk's aesthetic. This will use the Web Audio API to capture audio and create clean, geometric visualizations.

I've created a minimalistic and futuristic music visualizer inspired by Kraftwerk's aesthetic. Here are the key features:

Features:

• Audio Capture: Uses Web Audio API to capture audio from your microphone/system

• Three Visualization Modes:

  • Bars: Classic frequency bars with grid overlay
  • Circle: Radial frequency display
  • Wave: Waveform visualization

• Kraftwerk-Inspired Design:

  • Clean geometric shapes
  • Neon color palette (cyan, magenta, yellow)
  • Grid patterns and minimal interface
  • Retro-futuristic typography
• Theme Support: Toggle between light and dark modes

• Interactive Controls:

  • Sensitivity adjustment
  • Keyboard shortcuts (Space to play/pause, H to hide controls)
  • Mode switching buttons

Design Elements:

• Colors: Cyan, magenta, and yellow gradients in dark mode; blue, red, and orange in light mode
• Typography: Thin, spaced-out fonts reminiscent of electronic music aesthetics
• Grid System: Subtle grid overlays for that technical, precise feel
• Glow Effects: Subtle neon glow effects on the visualizations
• Minimalist UI: Controls fade away for immersive experience

The visualizer will ask for microphone permission to capture audio. For the best experience with computer audio, you might need to use virtual audio cables or enable "Stereo Mix" in your system's audio settings.

I'll redesign the visualizer with a more minimalistic approach, fix the alignment issue, and implement system audio capture to pick up music instead of microphone input.

I've redesigned the visualizer with a much more minimalistic approach:

Key Improvements:

Minimalistic Design:

• Monochromatic color scheme: Primarily black/white with minimal cyan accents
• Clean typography: Ultra-thin fonts with wide letter spacing
• Reduced visual noise: Subtle grids and minimal UI elements
• High contrast: Pure black/white for maximum clarity

Fixed Alignment Issues:

• Proper frequency range: Now focuses on mid-range frequencies (10%-80% of spectrum) instead of full range
• Better data distribution: Uses power curve to enhance visual distribution
• Correct canvas scaling: Fixed pixel ratio and coordinate system issues
• Centered visualizations: All modes now properly distribute across the full width

System Audio Capture:

• Screen sharing method: Uses getDisplayMedia() to capture system audio
• Automatic fallback: Falls back to microphone if system audio isn't available
• Audio source toggle: Switch between system audio and microphone
• Better frequency analysis: Enhanced FFT settings for music analysis

Enhanced Audio Processing:

• Improved frequency filtering: Focuses on musical frequencies
• Better smoothing: Reduces noise and creates smoother animations
• Dynamic range: Enhanced sensitivity controls for different audio levels

The visualizer will now ask for screen sharing permission to capture system audio. When you click "System" mode and start the visualizer, select "Share audio" in the browser dialog to capture your computer's audio output instead of microphone input.
