How is audio represented graphically?
Sound waves can be graphically represented by plotting the density or the pressure variation against the distance at a particular instant of time.
What does an audio 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.
What is the visual representation of audio called?
A spectrogram is a visual representation of the spectrum of frequencies of a signal as it varies with time. When applied to an audio signal, spectrograms are sometimes called sonographs, voiceprints, or voicegrams. When the data are represented in a 3D plot they may be called waterfall displays.
What is a graph of audio called?
A spectrogram is a detailed view of audio, able to represent time, frequency, and amplitude all on one graph.
