Spectrum to EQ curve

I have Audacity 3.5.1

I just downloaded NY Spectrum to EQ curve. I am no sound engineer so I may come off a little clumsy in this post.

I am an audiobook narrator and I have just recorded a chapter that I love the sound. The (Spectrum Graph?) looks great. I need to export a file from the spectrum graph from book chapter 5 and put it into the filter curve eq to plot the curve to all other chapters (i know I would need to do each chapter separately).

I am fairly good with audacity. I’ve been using it for about 2 years, However, I am new with this specific command, so I would need someone to go step by step with me to understand how to do this.

That plugin does not work with Audacity3 :frowning_face:
There are $tore-bought plugin$ which can match EQ which work in Audcaity3 …

[ I think there is a try-before-you-buy option ]
