Hey all,
There is a fantastic compendium of parametric EQ settings for many models of headphones, in a github repository called "AutoEQ": GitHub - jaakkopasanen/AutoEq: Automatic headphone equalization from frequency responses
The typical route seems to be setting up a parametric EQ at the operating-system level, so that all audio gets routed through it. However, this is a bit of a pain and/or expensive, particularly when you have multiple computers / OS's.
I'd like to look at the possibility of using a DSP to make a physical widget which can implement the AutoEQ repository. I'm a newb when it comes to DSP, so any and all feedback / advice is welcome here.
(meta note: I wasn't sure if this belonged in the "headphones" or "digital source" subforum)
It looks like there is a relatively cheap set of DSP boards from WONDOM built around the Analog Devices ADAU1701: WONDOM | STORE
Does anyone have any experience or opinions with that DSP?
Any other DSP's or boards I should look at? How would you approach this project?

Richard Marsh discussed just such an implementation in his Linear Audio article "A Headphone/Buffer Amp and Auto-EQ for Headphones". (LA/Volume 3, April 2012). Jan will sell you the article for EUR 0.49.
