About the waveform display
The waveform display shows audio as a series of amplitude peaks and valleys. The x-axis (horizontal ruler) measures
time, and the y-axis (vertical ruler) measures amplitude on a decibel scale that ranges from –∞ (negative infinity) for
silence to 0 dBFS for loud peaks. Quiet audio has both lower peaks and lower valleys than loud audio.
With its clear indication of amplitude changes, the waveform display is perfect for identifying percussive changes in
vocals, drums, and more. To find a particular spoken word, for example, simply look for the peak at the first syllable
and the valley after the last syllable.

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.
