[music-dsp] spectrograph / sonogram visualization

[Aaron Brick]

hello all,

i'm new to the list, and finding it fun & educational. thanks for having me.

i have been experimenting with visualization techniques, and having gotten
familiar with the conventional amplitude/time and fourier
amplitude/frequency graphs, i'm trying to determine how to get a
frequency/time graph; these are called spectrographs or sonograms?

there is a built-in function called "specgram" which i have not had success
using; since i want to understand the theory of such a transform i'm asking
here. also, are there any other useful 2D visualizations?

thanks very much,

aaron.
