Frequently Asked Questions

What frequency range does the visualizer show?

The visualizer displays the frequency spectrum from 0Hz to 16kHz, covering the full range of human hearing. This includes sub-bass, bass, midrange, presence, and brilliance frequencies.

What visualization modes are available?

We offer 7 modes: Bars (frequency bars), Circular (circle spectrum), Wave (waveform line), Spectrogram (time-frequency heatmap), Mirrored (symmetric bars), Radial (radiating bars), and Dots (intensity points). Each mode displays the 0Hz–16kHz frequency spectrum differently.

What is a spectrogram?

A spectrogram is a visual representation of the spectrum of frequencies over time. It displays frequency on the vertical axis, time on the horizontal axis, and intensity as color brightness. It's widely used in audio analysis, music production, and sound design.

Why 16kHz and not higher?

16kHz covers the full range of human hearing (20Hz–20kHz). Most audio content falls within this range, and frequencies above 16kHz are typically not perceptible to most listeners.

Is my audio uploaded to a server?

No! All audio processing happens locally in your browser using Web Audio API. Your files never leave your device, ensuring 100% privacy.

Can I use the visualizer for commercial projects?

Yes, all visualizations are royalty-free. You can use them for personal or commercial projects.
