klangbild

An immersive web-based audio player and visualizer that transforms music into stunning visual experiences using the Web Audio API and real-time graphics.

Background

klangbild emerged from my fascination with the intersection of audio and visual art. The goal was to create a web application that could analyze audio in real-time and generate corresponding visual representations, making music not just something you hear, but something you see and experience.

Technologies & Tools

• SvelteKit
• Web Audio API
• Tailwind CSS
• HTML5 Canvas
• JavaScript

Features

• Real-time audio analysis and visualization
• Multiple visualization modes (waveform, frequency, spectrogram)
• Responsive design for desktop and mobile
• File upload and drag-and-drop support
• Customizable visual effects and color schemes

Challenges

The main challenge was achieving smooth real-time visualization while maintaining good performance across different devices. Optimizing the canvas rendering and managing the Web Audio API efficiently required careful consideration of frame rates and memory usage.

Learnings

• Web Audio API provides powerful tools for audio analysis
• Canvas optimization is crucial for smooth animations
• User experience design is essential for creative tools
• Performance considerations are critical for real-time applications
