Again, no, 25 dB of attenuation was not applied to achieve this. There is indeed 25 dB of peak to peak variation in the response and typical of about every room measurement I receive and I have received hundreds from around the world. But again, this is not how digital room correction works using FIR filters. As @tktran303 has suggested, let me take this on in another thread or better yet, a video I have been planning for this precise topic. of how state of the art FIR filtering actually works. So I will bow out of this thread as it is a review of a product and get back to you with a walkthrough so folks can see how it is achieved. Cheers.
Thank you, Mitch, I will be subscribed to the other thread!
