Not without standardizing the scale, color, and other display aspects of the spectrograms. An uncropped photo of a rabbit still looks like a rabbit (as long as it isn’t so far away that it’s just a dot in the photo). A spectrogram looks radically different depending on the scale you use. Additionally, people may use different color scales (grayscale will look different from inverse grayscale which will look different from various color scales).
Edit to add: there is a feature request (Automatically add a spectrogram view to observations with sounds) that if executed, would produce standardized spectrograms for audio when uploaded.
