a photographic record of a spectrum
a display of energy levels as a function of frequency vs
a display of the frequency content of a signal drawn so that the energy content in each frequency region and time is displayed on a grey scale
a graph of Apple iTunes Plugins for Apple iTunes Apple iTunes Plugins for Apple iTunes
a graph that shows time on the x-axis, and wave frequency on the y-axis
an application used to visualize music based on frequency analysis
a plot of the short-term power of the signal in different frequency bands as a function of time
a visualization technique for acoustic events or audio material
a plot of sound frequency (Hz) against time (seconds).
A machine-made graphic representation of sounds in terms of their component frequencies, in which time is shown on the horizontal axis, frequency on the vertical axis, and the intensity of each frequency at each moment in time by the darkness of the mark. Shows the frequency components of a soundwave, with the relative intensity (indicated by the darkness or color) at each requency (vertical axis) plotted as a function of time (horizontal axis). (LC:297) representations of the amplitude and frequency of the componet vibrations composing a complex oscillation (by Fourier analysis).(H:555)
used interchangeably to refer to either (1) the instrument used in acoustic phonetics to provide a visual graph of acoustic features representing a given utterance or (2) the graph itself.
a photograph of an astronomical spectrum.
Visual representation of sound.
The spectrogram is the result of calculating the frequency spectrum of windowed frames of a compound signal. It is a three-dimensional plot of the energy of the frequency content of a signal as it changes over time.
