Spectrum Analyzer

What is Spectrum Analyzer?

Spectrum Analyzer displays the frequency content of audio in real time using FFT analysis. Upload an audio file or use your microphone to see frequency distribution, peak levels, and spectral patterns on a responsive canvas visualization.

How to use

1. Upload an audio file or select microphone as the input source.
2. Adjust FFT size, frequency range, and visualization style (bars, line, waterfall).
3. Play the audio and observe the real-time frequency spectrum display.

Result

A sound engineer uploads a vocal recording and identifies a resonance peak at 3.2 kHz that needs EQ correction, visible as a persistent spike in the spectrum display.
