AV Rant #402: Interview with Chris Kyriakakis of Audyssey

October 1st, 2014 1 comment

This week we bring you a special interview with Chris Kyriakakis of Audyssey. In it, Chris addresses all the questions you asked and some you didn’t including:

1) What are the things to remember between the different versions of Audyssey?

2) What are some of the differences between FIR filters, parametric EQ filters, “notch” filters, etc.? And what does Audssey MultEQ use? (from Andy E.)

3) What are the sampling rate and bit-depth limitations of the various versions of MultEQ?

4) Some AVRs that include MultEQ XT or MultEQ XT32 also say that they “support MultEQ Pro”. What is MultEQ Pro? And how close does MultEQ XT32 with Sub EQ HT get to MultEQ Pro without the upgrade? (from Jason S.)

5) Should speakers that measure very well anechoically still be EQ’d? (from Andy E.) Are there any special considerations when setting non-traditional speakers such as electrostatic or magneplanar, etc.? (from Matthew D.) What about di-pole Surround speakers where the 1st measurement position will be in the null? (from Jared M.)

6) We’ve frequently recommended using Audyssey Dynamic EQ. Can you explain how Dynamic EQ works – especially the “Reference Level Offset” feature?

7) What about Dynamic Volume and Low Frequency Containment – how do those technologies work?

8) So Rob H. has introduced this myth that setting an AVR’s master volume to 0 (zero) dB prior to plugging in the Audyssey setup microphone improved the automatic setup results vs. leaving the master volume at some other setting (eg. -30dB). Is there any possible way that the setting of the master volume level prior to plugging in the setup microphone is actually making any difference what-so-ever?

9) What parts of the automatic setup process are handled by Audyssey? What parts of the setup process are dictated by the AVR’s manufacturer? For example: speaker distances, trim levels, sizes (small or large), crossover frequency.

10) Home Theater Shack has a massive “Audyssey FAQ and Setup Guide” (LINK). It’s far too large to go over everything, but we’re particularly interested to know whether their description of “How Audyssey Works” (LINK) is accurate. And we’d also like to know if their examples of various microphone placement patterns (when using a version of MultEQ that supports taking measurements from several different positions in the room) is good advice that should be followed (LINK). –(from Tony C.)

11) Related to the last part of the question above, How does Chris personally go through the Audyssey automatic setup and room correction process? Does he exit the room completely or stand in a particular spot within the room during the measurements? Does he use a particular microphone stand? Does he place the microphone in a particular pattern? (from Cameron K.)

12) Is Audyssey MultEQ going to change or introduce a new version now that Dolby Atmos is here and other “immersive audio” formats are on the horizon? Is Audyssey looking at a way to implement elevation measurements? (from Cameron K.)

13) How will the current implementations of MultEQ cope with the Atmos-enabled upward-firing speakers and Modules?

14) This year, it appears as though Onkyo/Integra opted to no longer license MultEQ. That leaves fewer manufacturers that are still offering MultEQ in their AVRs and Pre/Pros. Is Audyssey MultEQ going away? (from Cameron K.)

15) Audyssey as a company offers more than just MultEQ, what would you like to share with our listeners about Audssey’s other products and services?

AV Rant #401: Budget Speaker Recommendations

September 25th, 2014 1 comment

Special thanks to Niels and Todd for supporting the podcast. We can’t do this without you! This week, an announcement about our Audyssey interview with Chris Kyriakakis and an update about our interviews with the Digital Media Zone guys. If you have HTPC or home integration questions, get them in now. Camereon sent us a link to the first reported sighting of Dolby Atmos in a tablet – the Kindle Fire HDX 8.9 (LINK). Dolby also released more information about Atmos Mobile (or whatever they are calling it). (LINK) Mike is interesting in more speakers on his ceiling, Nick compared three of our favorite speakers and reports and he also has a sub recommendation, and Sim wants to know what we think of multi-tweeter speaker designs. Infinite Gary has some questions about powered speakers, Atmos speakers, and whether a reflective floor or reflective ceiling is worse. Bill is planning his home theater and has questions about screen size and projector choice, Damon asked for some budget speaker recommendations (LINK) and Rob forgot to mention EMP Tek (LINK), and Tim is upgrading his 90’s equipment and wants to know what to keep and what to toss. Rob and Tom disagree on that one. Cameron has some questions about localizable bass and what to do with his OTA antenna, Jay is curious about amplifier ratings, Dan wants to know who to trust when shopping for a TV and our specific recommendations, Michael is having DVR issues, and Leighton wants to know if he should upgrade his speakers.

Special thanks to Niclas H. for supporting the podcast. His work to get us on TuneIn is much appreciated. Don’t forget to get your home automation and Audyssey questions in. We’ll be doing interviews soon. Steven has a suggestion on how to add a sub to your system, Andy recommends the videos from the Southeastern Michigan Woofer and Tweeter Marching Society (LINK), and Barney is interested in the CEDIA announcements from Trinnov (LINK). Gary has some questions about DTS UHD, Anthony Grimani’s assertion that the subwoofer crawl doesn’t work (LINK), Grimani’s high-end speaker offerings (LINK and LINK), and an article about 2.35:1 screens (LINK). Kevin wants our help on what to buy next for his growing home theater, Michael has a crossover question and a problem with connecting a record player (vinyl) to a receiver, and Bruno is concerned about a light in his home theater. Cameron is worried about a planned SVS sub shaking his doors and the thin jumpers on his speakers while Sim has a subwoofer placement question. Tom talks a bit more about the Oppo PM-2 headphones (LINK) and Rob makes a very strange recommendation.

September 10th, 2014 14 comments

Tom is back and he’s determined to keep the podcast under two hours…and he DOES! Thanks to E. Don and Robert for being our listeners of the week by supporting our podcast. Your donations keep us going. We have a few announcements about upcoming interviews so get your questions in now. Eliezer enjoyed Lee, Jonathan remembers DAK, and Cameron is tests out slap echoes (time to look into room treatments). Gaylen updates us on his Onkyo replacement saga, Jared has some information on B&W headphones (reviews HERE and HERE), and Tom gets the skinny on setting 0dB before running Audyssey. Has Michael found the most decoupled speaker (LINK)? Alan found our talk of subs last week interesting and wants to take a look at the pdf’s that Rob mentioned last week (links below). Jared wants some advice on dipole speakers and Audyssey, Mark is looking for advice for his Dad with surround sound speakers and subs, and Barney wants to know how Trinnov and Dolby Atmos will work together. Jay switched his sub cable and now has a thump, Jonathan wants to tailgate with good sound, and Gary wants to know what screen we’d pick. Michael is looking for help on how to read subwoofer specs, Bruno wants to know how to plan his home theater, Alan wants to know if mixing speakers with different sensitivities could cause damage, and Bill is building a home theater and wants to know if he should move a wall.

AV Rant #398: Lightning in a Lee

September 3rd, 2014 5 comments

Jeff G. is our Listener of the Week. Thanks, Jeff, for supporting the podcast. The Dolby Atmos Speaker Positions photo album was a hit (LINK). skriss corrected us about why Audyssey Dynamic EQ can sometimes create bloated bass. John thinks gaming PCs top consoles. Lee just built a new PC. And here’s a guide (LINK). Gary thinks some home theater seats are dumb, he’s interested in Datasat as an alternative to Trinnov (LINK), and he wrote to Dolby regarding Pro Logic now that Dolby Surround is here. Ashley asks about 3D TV calibration and speaker wire lengths. Nathan and Eliezer both saw a ridiculous “cable calibration” ad (LINK). Zach wanted to learn more about Burmester products. The review he found made Rob lose it (LINK). Atul asked about Bose vs. JBL and got the quickest answer ever. Joe and Allen both had subwoofer placement questions. Rob wrote directly to the experts at SVS, and the news is good! Lee fills us in on his current bass woes. Michael asked about speaker stands. Cameron asked about slap echo (LINK). Raul loves his new projector, but he isn’t so pleased with having to use “high altitude mode”. And Frank has possibly our most unique question yet: he’s building a gigantic model train and wants to shake the earth with sound!
