Popular Post mitchco Posted June 2, 2020 Popular Post Share Posted June 2, 2020 It is unfortunate how few people really understand Digital Room Correction 😞 While Audyssey (and many others) call their products digital room correction, they are far from SOTA. Matt did a nice job of showing that with Audyssey. However, nothing in the video applies to SOTA DRC products and this is where it goes sideways. Here I explain what the technical issues are with Audyssey, miniDSP, Trinnov, etc as the tech used is limited. https://www.audio “science” review/forum/index.php?threads/audyssey-room-eq-review.12746/page-10#post-380033 EDIT: I can't get the link to paste properly. Copy the link and remove the spaces and quotes around "science" Acourate and Audiolense are SOTA DRC products, way ahead of the pack, based my comparisons of these products over the last 10 years. The simulations produced in these two products are virtually identical to the measured response. I have done this dozens of times, even here on AS if you look at my articles that have a validation section you can see for yourself. My book has several comparisons of the simulations and the measurements, down to a .25 dB tolerance match across the band. What you see is indeed what you get. Wrt on axis, versus off axis measurements. In my my book, I show a detailed example of using a single Acourate measurement analysis to design to generate a DSP correction filter. I then used REW to measure at 14 different locations over a 6' x 2' grid area like this: Here are the results: It is too bad I can't invite folks over for a listen and can hear with ones own ears how smooth and even the response is no matter where one sits on the couch. @asdf1000 I have asked you before, have you tried Acourate or Audiolense yourself? If not, there are demo versions of both that you can try with the tutorials I have written on this site. You can also validate for yourself that the simulations indeed match the measurements perfectly. You can also verify for yourself the question of a single analysis measurement versus multiple measurements... and listen. Good luck. thewas, The Computer Audiophile and asdf1000 2 1 Accurate Sound Link to comment
