Thank you for this! It's awesome. You should just make a git repo so that you can quickly update if you wanted to.

Does this work as expected in newer EasyEffects versions? Trying in T16 Gen 1 AMD but don't notice much of an improvement.

The preset format has changed for EasyEffects 7.0.0: https://github.com/wwmm/easyeffects/blob/master/CHANGELOG.md#700
The changelog states that it should be possible to load old presets but since I'm still on 6.3.0 I can't test that. So it's possible that this preset doesn't work with EasyEffects 7.0.0.

I may try to make every change by hand in EasyEffects to mimic this config :P

Thanks for this preset, makes a massive (positive) difference on my AMD P14s Gen2! I searched for "lenovo p14s loudspeakers suck" and found this :D Sure there's a bit distortion going on but way better than not hearing those frequencies at all.

PS: Running EasyEffects 7.0.0 without issues.

In case, you didn't know, you can improve the sound of your headphones by using these presets here: https://github.com/jaakkopasanen/AutoEq/tree/master/results

Those guys use very expensive measuring equipment to get the best sound out of many, many headphones.

This would be the corresponding file for my Beyerdynamic DT700 Pro X: https://github.com/jaakkopasanen/AutoEq/blob/master/results/oratory1990/harman_over-ear_2018/Beyerdynamic%20DT%20700%20Pro%20X/Beyerdynamic%20DT%20700%20Pro%20X%20ParametricEQ.txt

You can just import them into EasyEffects.

i've applied this to my ideapad 5 15itl05 and the sound feels much better!

This is fantastic on my T14s Gen 1!

Easy Effects 7.0.8 ported the Filter effect to Linux Studio Plugins which requires adjusted parameters. The updated ersion can be found here: https://github.com/sebastian-de/easyeffects-thinkpad-unsuck
