There is a project on GitHub created by Jaakko Pasanen called AutoEq in collaboration with audio Masters like Crinacle, Oratory1990, and Innerfidelity that have created a huge repository of frequency responses that automatically equalise your IEM’s or headphones with no prior knowledge of how to EQ but can significally improve the sound of your gear.
Other know applications I know of that use this same EQ functionality is SoundSource by rogueamoeba and eqmac by emac.app.
Having 1000’s of EQ’s at your disposal, that you can select with no experience, no need for additional hardware, and on-the-go would be incredible. I for one can really appreciate the difference an EQ can make to an IEM or headphone which is why the next evolution of PLEXAMP needs this feature recommendation, please!
Thank you in advance.
