  1. Is anyone been able to use the software version of Dirac with their Microrendu or similar DLNA network player? If so can you please describe your signal path. What software are you using, Jriver, HQPLayer, Roon etc.
  2. Hi all, please bear with me because I will describe my system first before go to my question. I plan to try Dirac as my DRC. I use win 8 and JRiver 19 as a player outputting 2.0 channels since my DAC ionly accept 2. 0 channels input and outputting 2. 0 as well. My set up is pretty simple. Laptop - USB - 2ch DAC - unbalanced RCA - integrated amplifier (with LR outputs) - the mains speakers has passive XO and connected by speaker wires from speaker terminals in the integrated. However for my stereo subwoofers the chain is a little different : preamp LR output - Behringer DCX2496 (active crossover with stereo subwoofers output) - powered subwoofers. Again the Behringer would be used srictly as an active XO for strereo subwoofers only. It won't have any connection to my mains at all. I want to run my mains "full range" without HPF and let their natural drop off naturally. My concern is the Behringer's latency. I don't know the exact number yet but expect to get reply from Behringer soon. But that's kind of not the main point. My point is if the latency too high that I have to move the subs closer to my sitting area, I can't do that without involving a divorce lawyerr LOL. Here is the main question, assuming the Behringer's latency is 5ms and I cross the LPF at 120Hz/24db, would I be able to apply 5ms delay for frequency above 120Hz (hopefully I could set the slope to 24db also) using Dirac to compensate the delay caused by Behringer? Or perhaps JRiver could do that as well? Assuming eiter Dirac or JRiver could do group delay but not be able to set the slope below 120Hz) Am I correct to say hat means all my speakers are time alligned,? What will happen on the over lap freq around 120Hz? My mains are small ported monitors which roll off around 100Hz with 24db slope. So there is a considerably huge 20Hz gap between 100-120Hz and some freq bellow and above those points (the over lap freq down slope). So I imagine if my subs are delayed because the latency from the Behringer while my mains are not delayed I don't think I would get good sound. Am I correct to expect that the sound near the XO LPF point would be bad? Would anyone kindly explain in layman terms how the sound will be affected. Such as the sound near that freq would has "echo" or maybe they would out of phase and produce cancelation or that group delay would create deep null/peak in my freq response, etc? And again could DIRAC solves my problem? Note: I apologize for my writing errors and wrong technical terms. Feel free to correct me. My native language is Indonesian and I'm very new in home audio / HT hobby also don't have EE knowledge at all. Cheers, Thomas Narukama
  3. I have an 80 Hz crossover enabled in my Sound Blaster Zx with speakers set to "Small" so measurement is done with the crossover applied. As you can see there are massive nulls and resonances in my room. The LFE channel also has a massive dip of -16 dB at 50Hz. I have a Wharfedale SPC-12 and I can only listen to my system at something like -12.0 dB before the subwoofer severely distorts. The PC is connected via analog to my receiver so there is no DSP in the receiver. Is it possible that the crossover is behaving unpredictably when receiving filtered audio from each channel which has massive cuts and boosts? Could the total boosts in each channel be clipping once they are crossed over? As far as I understand, unless Dirac does its own crossover before filtering there will always be problems. The speakers and sub have to be measured without crossover. Then based on the findings, Dirac should apply its own crossover and mix the LFE channel before applying any filtering. Applying a digital crossover at a later stage will always result in some kind of clipping or overdrive. Basically measurement should be done without crossover and filtering should be done after crossover. It can be done with advanced routing but that has problems of its own and defeats the simplicity of the Dirac playback device.
  4. Hi there! Been here a while, ghosting Flak and a lot of threads on the Dirac LRCS subject. I've found a few target curves in other threads but they were simply pictures of the curves. I'd really like to try target curves developed by users who have had way too much time fiddling around. Here's a link to my first target curve. I've also added it as an attachment. Isn't overdoing it just the way we like it..? torklan_target1.txt
  5. Hello, The system: MacMini with Audirvana DAC LessLoss 2004 Pre-amp Nagra PL-L Power monoblocks Nagra MPA Speakers Vivid Audio V1.5 Subwoofer JL-Audio F112 (with dedicated power line) The problem: Even though these are all high-end components with an amazing resolution and a sound I love, I'm fighting with the fact that the system's performance is being very limited by my current living room. I tried several full range speakers and they all had serious bass problems. Apparently my living room is the culprit. So I decided to go for a pair of monitors and a good subwoofer with room calibration. That kind of made it bearable to listen to music there. But still... my system doesn't sound relaxed. Thanks to the subwoofer my main problem is now with the higher frequencies. I find that when I start raising the volume, the music quickly becomes tiring and confusing. So I end up avoiding music with lots of dynamics or feel tempted to start lowering the volume. But this is not acceptable for me. An acoustics specialist went to my home and after measuring the living room, said its proportions are very bad for listening to music. He said the first thing to take care of were the first reflections but I have a window on one side and a sliding door on the other, both right where treatment should be applied, which makes it a hard case. Still, he said I should install diffusion panels on the back wall and on the ceiling. I'm very reticent to invest so much money into something which will have a serious aesthetics impact and without the possibility of testing it. The salesman is suggesting that I buy Amarra iRC saying it probably solves a good part of my problems. But not only I'm fond to Audirvana, I also don't like the idea of being stuck to Amarra. And then I heard about Dirac Live. The questions: 1. How much of this will Dirac be able to solve? Will it reduce the impact of first reflections for example? 2. Won't the Dirac algorithm reduce the quality of the result (detail, etc), since it's transforming the information? 3. Would it still be advisable to put diffusion in the back wall for example? (I consider putting it in the back wall, but I really would like to avoid installing it in the ceiling, even though I hear it's much more important there) 4. Will Dirac Live (2 channels) work fine even though I have a subwoofer or will I need the full version because of it? 5. How will Dirac's room correction relate to the subwoofer's room correction? Should I turn of the subwoofer's room correction? Thanks in advance! Nuno
