I would love separate L-R EQ (though for hearing loss compensation rather than in car listening). Where to put / how to implement this script, in the meantime? Thank you!
Hi Pawel,
You can enable 'live programmable dsp' then select a type (any type will do). At this point click 'edit selected script' and paste the contents of your desired scripted within it. You can either make the adjustments in this window or by going into the 'additional script parameters'
I am currently using this eq which has 8 parametric EQ per channel, delay and an all pass filter.

Amazing, thank you. I have saved your example as a separate script (Pawel_EQ_LR.eel) and imported it — now just need to tweak it. It's so helpful :)
Glad to hear it! Set the all pass filters on both channels to 0 as well as the delays on both channels!

I did. Here is my script, in case it's helpful for anyone (and may I suggest that equalization / compensation for hearing loss is added to the app description in Play Store? I spent ages looking for one, and this one is just amazing!).

Hello... Very useful as I was looking for something like this. May I ask you what type of filter this uses, like peak filter, etc.
Hi FlavioPonte,
They are parametric biquad IIR filters.

Thank you for your work.
Hello,
First of all thank you for taking the time to develop this application, much appreciated! I was hoping to implement an EQ per channel for ppl that want to EQ a car for off axis response and time alignment. Taken care of the GUI and string encoding/decoding and working through the library now. In the meantime I have been using this dsp script if anyone is interested:
