DDMF has announced that the freeware equalizer IIEQ is now also available for Mac OS X in VST and AU effect formats.
The Windows version has also been updated: the GUI has changed, but under the hood it's still IIEQ. The Windows version is now also available as a 64-bit plug-in. The rest of the DDMF plug-ins will soon follow.
IIEQ is a free, fully parametric 10-band equalizer with its own, characteristic sound and low CPU consumption. The 1st and the 10th band are low and high shelf filters, respectively; all other bands are peak filters. Individual bands can be switched on and off (click on the small green buttons).
