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. Also, sonogram. When the data are represented in a 3D plot they may be called waterfalls.
What is a sound spectrogram used for?
A sound spectrograph is employed to record these waves in the form of a graph that may be compared to graphs of other individuals and differentiated. Though voice graphs (or voiceprints) have been used in courtroom proceedings, the accuracy of this technique in identifying individuals is…
What does an audio spectrogram show?
A spectrogram is a visual way of representing the signal strength, or “loudness”, of a signal over time at various frequencies present in a particular waveform. Not only can one see whether there is more or less energy at, for example, 2 Hz vs 10 Hz, but one can also see how energy levels vary over time.
