spectrogram visualization (specgram() usage)

[Aaron Brick]

hello all,

i don't understand how to use specgram(). when i follow the examples in its
help, it doesn't yield anything, and its output can't be directly plotted.
it says to also see "spectrogram", but i don't have it.

i would really like to better understand the algorithm behind this
transform, as well as why it takes so many arguments. any insight is
welcome!

thanks!

aaron.
