When iTunes went 64-bit, it broke every third party visualizer plugin. Yes, you could use them by setting iTunes to run in 32-bit mode, but that obviated access to more memory and improved security with 64-bit.

SoundSpectrum has announced the release of WhiteCap 5.7 and G-Force 4.3.1, which both do something nifty when they install — if you’re running OS X 10.5 or earlier, the installers will remove the x86_64 binary which would cause the stand alone apps to crash in older versions of iTunes. The latest version of Apple’s jukebox + kitchen sink would refuse to load these visualizers.

These issues have been addressed. Additionally, the updated plugins include a range of other improvements and tweaks, including new (BT) colormaps and improved audio support.

Also from the good news department, SoundSpectrum (a.k.a. Andy O’Meara) is saying we should be seeing Softskies and Aeon releases soon.
