In a spectrogram representation plot — one axis represents the time, the second axis represents frequencies and the colors represent magnitude (amplitude) of the observed frequency at a particular time.
WebIt plots over the time, for a given range of frequencies, the power (dB) of a signal. This allows us to spot periodic patterns over time, and regions of activity. Spectrograms are used in state-of-the-art sound classification algorithms to turn signals into images and apply CNNs on top on those images. There are several types of spectrograms to ...
