WitrynaA spectrogram shows time on the x-axis and frequency on the y-axis. That means the bottom of the spectrogram is the lowest frequency, and the top is the highest frequency. Moving left to right on the spectrogram represents moving forward in time. A spectrogram also shows a third dimension: amplitude (loudness). 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. Spectrograms are used extensively in the fields of music, linguistics, sonar, radar, speech …
