About Spectrum Analyzer

About the Spectrum Analyzer

The Spectrum Analyzer shows how a recording's energy is spread across frequencies — bass on the left, treble on the right. It is a quick way to spot a boomy low end, harsh highs, or a noise problem you can hear but can't place.

Use it alongside the Equalizer to see what you are shaping.

Frequently Asked Questions

What does the spectrum show?

How much energy the audio has at each frequency. Peaks reveal dominant tones; a raised level across the top hints at hiss or noise.

How do I use it?

Spot problem areas — excess bass, harsh peaks, or noise — then fix them with the Equalizer and re-check.
