EQ curves can be converted into impulse responses. This means I can make a custom IR of headphone correction software, such as Sonarworks, and load it as an IR on the Quad Cortex. This lets me use my headphone correction curve directly on the Quad Cortex. Currently I have to use an IR loader block on every preset, which gets very tedious. Ideally, I would like to be able to load the IR globally, similar to the global EQ section. Being able to choose which outputs the IR is applied to would also be great, again similar to the global EQ. Essentially, I want the exact same functionality as the global EQ, but in the form of an impulse response. ---

Not _exactly_ what you’re asking for, but check out this existing request: > [@Please make Global EQ available for headphones](https://unity.neuraldsp.com/t/please-make-global-eq-available-for-headphones/10803): > > Hi, the introduction of Global EQ is super handy, but unfortunately it doesn’t work on headphones out. Most headphones need some sort of eq and that’s also true when working with IEM in manu contexts. It would be super nice if Global EQ was available for headphones as it is for main outputs. Thanks.
