## Description

Sharpen your audio engineering skills — random quiz questions from Ohm's Law to RT60, with instant formula explanations after every answer.

A quiz app for practicing audio engineering calculations with randomly generated questions. No login, no ads, no tracking — works completely offline.

■ Electrical
· Ohm's Law (current/voltage) questions
· Power (P=V×I) questions
· dB ↔ power ratio conversion questions
· Speaker impedance (series/parallel) questions

■ Delay
· Speed of sound by temperature questions
· Distance ↔ time delay questions
· BPM-based note length questions
· Haas effect (precedence effect) zone questions
· Multi-zone speaker delay (with precedence offset) questions

■ Acoustics
· Wavelength (λ) questions
· Period questions
· RT60 reverberation time questions
· SPL falloff by distance questions

■ Tempo & Pitch
· Playback speed ↔ pitch (semitone) conversion questions
· Loop BPM questions
· Buffer size / sample rate latency questions

■ Mixed
· Combined questions from all four categories above

Choose 5, 10, 15, or 20 questions per round — a fresh set of random questions every time. Each answer comes with an instant explanation showing the formula, and you can track your round progress, hit count, and accuracy in real time.
