Spectrographing Windowlicker
============================

Tuesday 27 January 2009 20:03

I've all my CDs ripped to oggs and served by
Mediatomb running on my OS X PPC to my Playstation
3 (just to avoid AirTunes). Ok, that was running
for a while, but now I looked at the import script
and found out the whole chain supports a bit of
Unicode. The issue is that the Playstation's user
interface is a bit annoying when you need to scroll
through lists of hundreds of artists or albums, so
that's why Mediatomb supports customizing the
generation of these lists through a JavaScript
import script. Using that script, I now have my
music first divided into an index of first letters,
and the next level is a combination of albums and
artists starting with that letter. But to
distinguish between an artist and an album I wanted
a nice indicator. Which is possible because I can
edit the import.js script as utf-8 and then
Mediatomb can treat it as utf-8 and the Playstation
also does utf-8. So I put in the Unicode symbol for
sun ☉ to indicate the entry is an album, and
renamed my server from New York to I♥NY just to
check that out. Then I wanted to get the notorious
second track of Windowlicker right, but that would
need MathML because it's a bit to complicated for
just Unicode. And just because you can't trust a
Wikipedia article, I checked the Spectrograph
myself by opening the ripped wav in Sonic
Visualizer. Would be nice if the Playstation had a
realtime spectograph visualizer instead of the just
a bit off useless ones. But the Wikipedia article
is right about the spectrograph: [IMAGE]
