GasLight :: 2013-05-27


GasLight was my first attempt at an iTunes Visualizer. Nothing groundbreaking – it’s essentially yet another frequency spectrum analyzer. It’s pretty customizable, though, and uses a whole bunch of pretty graphical tricks.

Technical details


Version 2 is fully compatible with iTunes 11 - apologies it's taken so long to come out. Since GasLight was first released, Apple have deprecated and/or removed half a dozen frameworks that it used to rely on, so it’s taken a while to rewrite it all. Some of my 9 year old code is pretty hideous, too.

It still has a number of rough edges, particularly in the text handling, but it ought to work fine for the most part, as long as you’re running 10.7 and iTunes 10 or above. I still need to get a Mac developer account so it’ll probably complain that it’s from an unsigned source, I’m afraid.

And no, this won’t run on the Windows version. I use a bunch of Apple specific OpenGL extensions, and the windowing code and configuration options are heavily tied to Mac code. I don’t have any plans to port this in the near future.

Screenshots don’t really do it justice, so just download it and give it a whirl…
