  1. I agree, it's quite painfully formulaic. Admittedly I watched it on a plane the other day but I watched Ant Man beforehand, totally different ball game.
  2. What sort of difference in thd have you seen from going to increased loads? This sort of data (thd vs freq at different output and under different loads) seems almost completely absent from published specs so I am curious to know what sort of real world impact is.
  3. https://yabb.jriver.com/interact/index.php?topic=98734.msg699035#msg699035
  4. I was referring to the use of zones to output to different locations and/or devices. It is not so much me over complicating zones as zones being able to be used for some relatively complicated use cases, it can be nice to have options though. BTW apparently that dsp preset approach wasn't working properly for video anyway, fix in the next build.
  5. The jriver DSP interface certainly has some ease of use issues.
  6. yep it would and it is see https://yabb.jriver.com/interact/index.php?topic=91434.0
  7. you have 2 choices 1) manually load and unload the DSP configuration before & after watching the film 2) set the DSP field on every film in your library
  8. It can be done. The feature to load/save DSP was introduced in MC20 and is described as NEW: DSP presets can be loaded per file by setting the DSP field (the list is from Load/Save on DSP Studio). This means you can enter it once, save it and then load it on a per film basis. Alternatively you set the value in the DSP field in your library. However if you do it this way, bear in mind that it is implemented in a slightly crap way atm, it loads it when you play it but doesn't unload it back to a default state when you stop. This means you'd have to update the DSP field on every other track with your default setup. Whether this works for you depends on your setup, I think it plays particularly badly with multiple zones for example.
  9. I didn't mean to scare you off!! To enter the filters in jriver is just those pics I showed of the jriver DSP. It is literally just clicking a few buttons. Ignore the discussion of exactly what filters to enter. It is a shame jriver doesn't support a simple way to import a filter set as that would make it way easier. BTW http://yabb.jriver.com/interact/index.php?topic=99096.0 is the current thread that collects various eq related features that people want in jriver. Feel free to post there to show support for some of those requests.
  10. ah right, yes I see what you mean red is, I think, the sum of your LFE filter cyan is using 2 LS with Q=0.707 plus 2 peaking filters; 1 at 17Hz, Q=1.5 and gain +5 & the other 12Hz Q=1.5 and gain +1 blue is cyan + another peaking filter at 35Hz, Q=1.5, gain -0.8 I don't think I'd recommend using that 19Hz peaking filter with the jriver shelf filter, it results in a fairly prominent notch in the shelf
  11. All of these are entered via the PEQ block in DSP studio. Note that if the PEQ block is before room correction then subwoofer means the LFE input channel, if the PEQ block is after room correction then subwoofer means the physical subwoofer output channel. You want the PEQ block to be *before* room correction. 1. Gain -4dB Click add/adjust volume Enter -4 Select subwoofer from the channel dropdown 2. Low Shelf 15Hz, Q of 0.94, +6dB 3. Low Shelf 15Hz, Q of 0.94, +6dB As per the previous post, this is not directly supported in jriver so you have to approximate. Click add/adjust low frequencies (low shelf filter) Enter frequency 15 Bandwidth 1 Gain 6 Select subwoofer from the channel dropdown Repeat 4. Peak 19Hz, Q of 2, +6dB Click add/adjust low frequencies (low shelf filter) Enter frequency 19 Bandwidth 2 Gain 6 Select subwoofer from the channel dropdown You can now just repeat the same procedure for the next block, just choose the relevant LCR channels from the channel dropdown instead of subwoofer. EDIT: see next post, the filters might need fine tuning for use with jriver.
  12. This is a v steep LS that has some overshoot at the top and bottom of the shelf isn't it? I guess this is because you wanted a steeper rise from the shelf? A low shelf with this Q is not supported directly by jriver. It's low shelf is described in terms of Q but, as I understand it, it really mean S (shelf factor) and it limits this to a max of 1. The formula to convert Q to S is listed in http://www.musicdsp.org/files/Audio-EQ-Cookbook.txtand is 1/Q = sqrt((A + 1/A)*(1/S - 1) + 2) where A = 10^(dBgain/40) If you solve for S you get 1/((((1/Q)^2-2)/(A+1/A))+1) which means you'd need jriver to accept a value of ~1.7 for the LS If you go with a shelf with a S of 1 (roughly a Q of 0.707 in the minidsp terms) and increase the gain to 6.2dB then you get the following; black is your version, brown is what jriver can support. I suppose this is close enough?
  13. I use Jriver and have applied these sorts of filters before. You just add them to the peq block in the DSP window. I can lost an example later.
  14. they are already there aren't they? http://www.speakerpower.net/order.html there is also http://www.speakerpower.net/dealers.html(I got mine from seaton)
  15. Probably worth following that up in http://data-bass.ipbhost.com/index.php?/topic/19-speclab-waterfall-scene-capture-tutorial/
  16. you don't need the DTS decoder no, at least not if using a recent jriver as that's supported by LAV now. you do need to be able to read BDs yes, I use anydvdhd.
  17. post 8835 in http://www.avsforum.com/forum/113-subwoofers-bass-transducers/1333462-new-master-list-bass-movies-frequency-charts-295.html#post23468771 it is page 221 of 566 for me but avs forum software is rubbish so working out a direct link is always tricky, the above is using the default no of posts per page
  18. I'm not sure I'd call that commentary a "review"
  19. go to File/Audio Files & Streams/ Analyse and Play File (with DSP) and choose the wav from the file dialog remember to switch your mic cal filter to bypass
  20. The method for calculating the composite rating is in http://data-bass.ipbhost.com/index.php?/topic/12-the-low-frequency-content-thread-films-games-music-etc/?p=86I would think the difference will be that the composite rating considers the whole film not just the most aggressive scenes. I don't see that there would be any difference between a actual voltage based reading and one based on dBFS as long as both are clean and you use an equivalent reference for the max signal.
  21. I verified it for Q of 1,2,3 and they look the same to me. The spreadsheet has a rather low resolution for higher Qs but it still looks accurate to me. I tested Qs 1,2,3,4,5,10 with +10dB gain at 60Hz, graph attached. I can share the mdat if anyone wants it.
  22. FWIW I bought mine from seatonsound, it was both cheaper and ships with http://www.neutrik.com/en/audio/powercon/powercon-32-a/nac3fc-hc on the end of the power cable. EDIT: actually now I reread my emails I see he said it normally comes with the powercon but he includes a terminated power cable, not clear from the above whether the connector is the problem or the cable. I suppose not such a big deal for us in the UK anyway.
  23. is BEQ for Tron Legacy available? (you can guess who got this for xmas!)
