About the spectral display

The spectral display shows audio by its frequency components, where the x‑axis (horizontal ruler) measures time and the y‑axis (vertical ruler) measures frequency. This view lets you analyze audio data to see which frequencies are most prevalent. Colors represent amplitude, ranging from dark blue for low amplitude to bright yellow for high amplitude.

The spectral display is perfect for removing unwanted sounds, such as clicks, coughs, buzz, hum and other artifacts. This is known as frequency‑space editing.
