Hey,  
I’m looking to switch from Equalizer APO to FxSound and the biggest thing holding me back is that the EQ is very limited  
I’m using [https://autoeq.app](https://autoeq.app) to get the correct my frequency response of my headphones, and I want to use that in your app  
I’ve seen people discuss about this before, I really think this should be implemented  
Thanks!

The Q value is 1.52743447, and the Bass Boost Effect works at 62,5 Hz (which I discovered by opening a Preset .fac file in WordPad).

For the feature request to add more EQ bands, see:

> <https://github.com/fxsound2/fxsound-app/issues/13>
>
> Multiple users have requested the addition of one or more bands at the low end o…f FxSound's current 9-band EQ, in order to allow more precise control of frequencies below 86 Hz (with 20 Hz generally accepted as the bottom limit of human hearing).

For the feature request about AutoEq Presets, see:

> <https://github.com/fxsound2/fxsound-app/issues/22>
>
> Multiple users have requested the addition/creation of AutoEq presets to be used… in combination with FxSound.
> AutoEq presets are automatically generated Equalizer settings tailor-made for various different headphone models, aimed mainly at neutralizing their respective frequency response output.
