Audio Dojo
Audio Dojo is a web-based interactive training platform that helps musicians and audio engineers develop critical listening skills through real-time audio processing and dynamic quiz generation.
This project demonstrates the ability to design and build a full-featured frontend system that combines complex logic, real-time interaction, and user-focused experience.

KEY HIGHLIGHTS
- Built a dynamic quiz engine that generates questions based on parameter combinations (frequency, gain, shape)
- Implemented real-time audio playback system with strict state control (original vs processed)
- Designed full user flow: setup → quiz → feedback → summary → history
- Developed persistent state management using Context API and localStorage
- Created export system (PDF & Excel) for user performance tracking
- Focused on UX: responsive layout, mobile support, and clear feedback loops
TECH STACK
