WebFeb 24, 2024 · Spectrogram Augmentation. The normal transforms you would use for an image don’t apply to spectrograms. For instance, a horizontal flip or a rotation would substantially alter the spectrogram and the sound that it represents. Instead, we use a method known as SpecAugment where we block out sections of the spectrogram. There … WebA spectrogram is a representation of a signal (e.g. an audio signal) that shows the evolution of the frequency spectrum in time.
