I think this could be removed since we only use the ParametricEQ

This is not needed. Check that the old EQ Settings are not empty. Do the conversion once and let the old EQ settings.

Great job. The settings view looks great. To be honest the calculation is way over my head. I have no idea if that what is displayed is correctly applied to the audio engine. I left a couple of comments.

I have two other questions:

Thanks BLeeEZ, I'll go through and apply the changes and update 😊 I used the CoreAudio engine calculations as the base, so hopefully they should be accurate. You never know with Apple whether that will change something in the future which will break the calculations. It's a very good thought, I will try to add a 'detail' slider to hide/show the detail such as the gain/cut calculations as some users may find it too technical. For your other questions:

|
Is there any progress on this? I’d love to see it implemented. |
|
Not yet from my side unfortunately. My work and family life has got crazy busy. I'll try and get the slider done soon. Maybe someone else is able to help out and clean the revised changes BleeEZ recommended? |

I noticed a gap in the market for music players that have really decent, but easy to use, Parametric EQ capabilities. Amperfy is my go-to music player. So I wrote one!
This PR swaps the existing graphic EQ system for a comprehensive Parametric EQ system.
I've run it through the testing and formatting tools in the Amperfy repo, all of which pass. I've built it locally on my Mac and tested using simulators, but would welcome on-device testing.
It would be great to be able to allow the user to switch between the existing graphic and Parametric EQ's. Happy to build this functionality out if useful.
