Mar 28, 2016 · [1] X-Curve Is Not An EQ Curve, Michael Karagosian, SMPTE 2013 [2] Ioan Allen describes the history of Dolby Sound at the University of San Francisco, [3] Presentation on Cinema Audio, PowerPoint presentation prepared by Dr. Floyd Toole concerning issues of audio reproduction and the current standards, Audio Engineering Society, 2012

Feb 14, 2016 · Cinema X-Curve Target Response The standard practice for movie sound production is the "X Curve" (from the letter "X" in Experimental) which was determined and codified in ISO 2969 and SMPTE S202 specifications in early 1970s. Figure 2 shows what its target response looks like.

Dec 8, 2016 · Basically the X Curve is used in the film industry for both production and playback environments (read theaters). Those particular speakers are designed specifically for film post production, so by industry standards, using the X Curve would be a requirement if they were actually being used for that purpose.

Mar 28, 2016 · I don't use the X curve or a modified one or any sort of EQ. I just play Dolby's noise filtered from 500-2K adjusted to -20, encoded in both Dolby TrueHD and DTS MA, and aim it to 85 dBC Leq (82 for surr.) with a SPL meter put on a tripod.

Mar 28, 2016 · Validity Of X-curve For Cinema Sound In my article in Widescreen Review Magazine published recently titled “There Is No “There” in Audio,” I made a brief reference to X-curve used for calibration of Cinema Sound and mentioned that there is no good reason to follow it for home theater...

Mar 28, 2016 · Dolby measure it using RTA / pink. And yes the goal is flat response from the speakers. (I.e. In a lot of cases, once a speaker system is calibrated to be "flat" in a large room, it'll be fairly close to the x-curve, but there are a ton of variables that can throw the correlation out if you're unlucky, obviously)

Feb 23, 2018 · It was concluded that X-Curve does not sound good and takes out too much of the high frequencies. Another conclusion was that theatres do not follow the X-Curve naturally from an acoustic point of view...ie the natural high frequency roll off is nowhere near that described by the X-Curve even though it is part of Dolby accreditation standards.

Feb 14, 2016 · The "correct" curve will vary based on the speakers dispersion characteristics, the size and characteristics of the room, etc. Also, a well engineered speaker will naturally give you the correct in-room slope, you don't have to force a target with room correction systems (such systems can however be used to reduce room interaction especially in ...

Aug 13, 2022 · It has correct positioning, proper soundstage, proper separation. And finally low end comparable to a subwoofer with monitor speakers (fortunately not that consumer Harman V-curve which amir uses, which is just horrible standard, imo!). All in all, DT 900 Pro X, to me, is a headphone worth double it's current 225€ price.

Feb 7, 2021 · Nice review. My primary issue with the DT770/1770/700 Pro X, other than the overemphasized treble, is the dip present in the lower-mids, causing quite a hollow sound. Thankfully with literally just one EQ filter you can remedy that issue. I'm assuming the DT770 Pro X is more similar than different to the DT770.
