Default Software VU Meter

I'd like to write VU meter screensaver for my player running on Raspbian.
Has anybody done that using Python? I believe ALSA API should be used for this task similar to this:
ameter
There is some Python wrapper for ALSA:
https://github.com/larsimmisch/pyalsaaudio
Is it the only way to go? Does ALSA use DBUS?
Is it possible to write spectrum analyzer using ALSA API?

Thank you! The first links give pretty good idea how that can be done in Python using mpd and without installing any additional library/software.
