Shazam uses audio fingerprinting technology that converts sound into spectrograms via Fast Fourier Transform, then identifies unique patterns to match against millions of songs. The system works by analyzing frequency peaks rather than melody or lyrics, making it robust to background noise. This technical approach allows near-instant song identification even in challenging acoustic environments.
