WebA 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). Webwhitened log-scaled mel-spectrograms. The average classifi-cation accuracy obtained is respectively 68% for the baseline and 73.6% for the best performing variant of the …
