WebDec 30, 2024 · Spectrograms will work with any network that can operate on images. A spectrogram, however, is not an image, and many image techniques will be inapplicable: Data augmentation via rotation: a rotated spectrogram doesn't represent the same process at all, or even any process (there may not be a signal that maps to a given 2D array). WebOct 13, 2011 · If you can identify the upper harmonics, showing up as horizontal stripes in the spectrogram, and find the size of the gap between them, this will be the fundamental pitch. Say your FFT resolution is very coarse under 200 hz, but you find a peak at 240 hz, 360 hz, and 480 hz. Well, this is a dead giveaway that the fundamental was 120 hz.
