When Audacity records a sound, that sound is put on a: ________________GridLineTrackBar graph

The correct term to fill in the blank is "Waveform."

When Audacity records a sound, the sound is represented visually on a waveform display, which resembles a graph. This waveform captures the amplitude of the sound wave over time, allowing users to see the fluctuations in volume. The x-axis typically represents time, while the y-axis represents amplitude. This visualization helps users edit, analyze, and apply effects to the audio tracks easily. The waveform can display various characteristics of the audio, such as peaks and troughs, which can indicate loud and quiet passages, respectively. This feature is essential for audio editing because it allows users to make precise adjustments to their recordings based on visual cues.
