The 6144 is an Audio Unit and Inter App Audio equalizer which aims to recreate the legendary sound of the Neve hardware EQs.

Now start turning the knobs on any of the five bands and you'll be amazed: it's really possible to add copious amounts of gain without ever sounding harsh, at all. The 6144 has been a not-so-secret weapon for audio engineers in the desktop realm for some years already, and is now finally available as an iOS plugin for use in an Audio Unit or Inter App Audio compatible host.
