We have developed an online spectrograph program with a bank of over 30 audio clips to visualize a variety of sounds. Our audio library includes everyday sounds such as speech, singing, musical instruments, birds, a baby, cat, dog, sirens, a jet, thunder, and screaming.

∗1. 1. National University of Singapore. 17 Nov 2020 To make building models that operate on time-frequency domain data - like audio or moving machines - easier we have now introduced the new In the spectrogram, the harmonics appear as horizontal lines. In this example, the pitch doesn't change, so the frequencies of the spectral lines are constant. Video created by Universitat Pompeu Fabra of Barcelona, Stanford University for the course "Audio Signal Processing for Music Applications". STFT equation After first considering the information content of a general Cartesian diagram, the upper limit of information content in a piece of sound spectrogram is derived.

Spek (IPA: /spɛk/, ‘bacon’ in Dutch) helps to analyse your audio files by showing their spectrogram. Spek is free software available for Unix, Windows and Mac OS X. Tweet

The horizontal axis represents time (in this implementation time is displayed in milliseconds) while the vertical axis represents frequency (in Hz). Create a spectrogram from a audio signal.

The link provides information of how we can reconstruct an audio signal from STFT magnitude. Even for that they highly rely on the signal itself for the magnitude portion. I want to see if we can extract the same information from the spectrogram image in the first place.
