isn't it just subtract the audio from the filtered output?
I guess you

There is an explanation in Miller's book if you like unit circle math:

can;t remember where I saw about this, but check this link

see the quote An easy and practical way to remove the zero-frequency
component from an audio signal is to use a one-pole low-pass

I guess you can get inverse freq response just by that

You could send the original signal in parallel and invert the phase by
multiplying with -1. You might have to delay
