I would caution against applying an EQ curve to headphones without review beforehand. If EQ includes large boosts (which the example image and table shows) that can easily introduce clipping distortion if applied linearly without appropriate headroom adjustments.<p>Additionally, depending on transducer performance large bass boosts may simply increase transducer distortion in the bass frequency. Some headphones respond well to EQ, and others not so much.<p>I am not opposed to EQ, but it should be applied judiciously, and at least partially by ear. I don't believe trying to exactly match a target curve will necessarily provide good results compared to a more judicious approach.
It even has settings for Apple’s Ear Pods [1] (the wired earbuds). I remember being surprised how applying these values makes them resemble regular headphones.<p>[1]: <a href="https://github.com/jaakkopasanen/AutoEq/tree/master/results/oratory1990/harman_in-ear_2019v2/Apple%20EarPods" rel="nofollow">https://github.com/jaakkopasanen/AutoEq/tree/master/results/...</a>
Autoeq is not just a collection of ready-made EQ settings for different headphones, it's also a database of measurements from few different review sites and a tool for creating custom EQ curves. Do you have a specific target that you like? You can create a custom curve tuned for that target. Do you want to know how a certain model of headphones sounds? You can make your current ones sound almost exactly like them.
Really cool project.
I created and opened up the design of a standalone DSP [1] that leverages AutoEQ. The DSP is optimized for our home brewed headphones for VR, but I’ve been using it for my desktop headphones too.<p>AutoEQ is not a perfect tool, but an amazing (and free) starting point to get the most out of your audio systems.<p>[1] <a href="https://github.com/tanvach/prettygood_dsp" rel="nofollow">https://github.com/tanvach/prettygood_dsp</a>
The precompiled AutoEQ/results/ tree has been a godsend, and so is Wavelet. I honestly would think about buying a pair of headphones that's not in it, unless I'm actively looking for a specific sound signature (but it's really all about price and comfort as far as I'm concerned).
FYI, EQs will distort audio. Especially if the adjustments are large.<p>Your average EQ will introduce phase shifts to the various frequencies that make up a sound.<p>Linear-phase EQs don't phase shift but they also introduce pre-ringing and post-ringing effects.
It would be interesting to compare the suggested EQ curves here vs. commercial offerings that claim to introduce a neutral response like Sonarworks. In theory I think they should be doing quite similar things, but curious if there are any real differences or if they land in the same general area.
If you have an iPhone X or older, you can jailbreak it and use EQE (<a href="https://eqe.fm" rel="nofollow">https://eqe.fm</a>) which is system-wide and has AutoEQ integration built-in
All this assumes the headphones are linear devices... which clearly isn't the case!<p>None of these tools seem to do anything but rudimentary nonlinear correction... Even simple things like measuring and cancelling harmonics nobody seems to do...
it's great project. No idea why some people do not want to eq their headphones at least a little bit. It can make a huge difference. Also frequency response is IMHO at least partially a matter of taste.
Unfortunately on Windows is uses EqualizerAPO which has to be re-enabled every time Windows is updated or it stops working. I've given up on my headphone EQs because of it.
