Hljóðbylgjulínum
Hljóðbylgjulínum, also known as sound wave lines, refers to the visual representation of sound waves. These lines are typically depicted as oscillating curves on a graph, where the horizontal axis represents time and the vertical axis represents amplitude or pressure variations. The shape and pattern of these lines convey information about the characteristics of the sound.
The frequency of a sound is perceived as its pitch and is represented by how close together
Hljóðbylgjulínum can also illustrate other sound properties such as timbre, which is the quality of a sound
