  1. Just keep in mind, if you want to use any of the BEQs that don't list S, you'll need to convert Q to S. I recommend Excel to do the grunt work. There's a bit of discussion about that earlier in this thread:
  2. Yes it is. Here's a link with an image from Logan the little bit of spoken word at the beginning and end removed:
  3. If you'll recall, 3II3d00d, I had to come up with a slightly different formula for Excel to work correctly. I'm not sure why our experiences different, but here's what I finally settled on for S: S = (A^2*Q^2+Q^2)/(A^2*Q^2-2*A*Q^2+A+Q^2) For A I used what comes from the Audio EQ Cookbook: A = 10^(dBgain/40) More specifically, I set up a spreadsheet where you input the desired dB gain in cell B1 and the target Q value in B2. Then I have a formula for A in E1 and S in E2. Here's what those formulas look like: A: 10^(B1/40) S: (E1^2*B2^2+B2^2)/(E1^2*B2^2-2*E1*B2^2+E1+B2^2)
  4. Sorry if this is seems like asking the obvious, but I want to make sure I understand correctly. You mean run a loopback measurement of the entire movie to see if the measurement matches what was posted in the graphs? I could do that. I suppose I was hoping for something that didn't take ~2 hours to verify. That, of course, assumes that this is easy for someone to verify my work. After I posted my question, I realized there is a quick way to do a sanity check. I took a look at a coupe of the more recent posts where maxmercy posted both S and Q. In both cases, if I plug his Q value into my Excel spreadsheet, my S and his match.
  5. I'm finally going back and redoing my BEQ filters for JRiver by converting Q to S. I'd love it if someone could take a look at my calculations and make sure I've done the conversions correctly: LCR: 1. Gain -7dB 2. Low Shelf 25Hz, S 2.35, +6dB 3. Low Shelf 26Hz, S 2.35, +6dB 4. Low Shelf 27Hz, S 2.35, +6dB 5. Low Shelf 52Hz, S 0.51, +5dB LFE: 1. Gain -7dB 2. Low Shelf 18Hz, S 2.32, +6.5dB (3 filters for 19.5dB correction) 3. Low Shelf 36Hz, S 0.51, +5dB Surrounds: 1. Gain -7dB 2. Low Shelf 22Hz S 2.28, +7dB 3. Low Shelf 23Hz S 2.28, +7dB 4. Low Shelf 24Hz S 2.28, +7dB 5. Low Shelf 25Hz S 2.28, +7dB 6. Low Shelf 22Hz S 0.53, +8dB
  6. Awesome. Now I have a reason to upgrade the MC22.
  7. What do you consider an aggressive house curve. Is something based on the Harman curve aggressive? That's not my exact curve, but it's the general idea.
  8. Not yet, but hopefully they'll get around to that soon enough. My assumption is that they'll start supporting S values greater than 1 before they start supporting Q values.
  9. Assuming you're planning to post the BEQ values in the thread, can I convince you to post S as well as Q. It makes implementation in JRiver easier.
  10. They would just point you back to the AVS review where the film is given a 100 out of 100 for audio: http://www.avsforum.com/san-andreas-3d-blu-ray-review/
  11. I wonder if the new 4k remaster is any bass-ier. It has an Atmos sound track, plus a 7.1 TrueHD track for those of us without Atmos.
  12. It looks like JRiver's 1.0 limitation for Q (or really S, but Q in the UI) means many of these BassEQ settings can't be properly implemented. I had previously created all of mine in JRiver 19, before they implemented notification that values over 1.0 are ignored. I've recently upgraded to JRiver 20, and while it imported my old BEQ filters, including ones with a Q>1, if I try to edit it, I get an error message notifying me of the problem. One of the best features in JRiver is how easily it allowed me to implement BEQ. This is a blow.
  13. Excel barked at that formula for S. There was an extra parenthesis, and for the life of me, I couldn't get it to result in ~1.7. Here's what I came up with: S = (A^2*Q^2+Q^2)/(A^2*Q^2-2*A*Q^2+A+Q^2) It comes back with a value of ~1.7, so it matches what you found.
