How do you read audio waveforms?

Reading an audio waveform is simple: the x-axis (horizontal) represents time, and the y-axis (vertical) represents amplitude. Basically, the higher waves are for louder frequencies, while the shorter waves are for softer sounds.

How do you describe waveforms?

A waveform is a graph that shows a wave's change in displacement over time. A waveform's amplitude controls the wave's maximum displacement.

What does a waveform represent?

The generic term waveform means a graphical representation of the shape and form of a signal moving in a gaseous, liquid, or solid medium. For sound, the term describes a depiction of the pattern of sound pressure variation (or amplitude) in the time domain.
