  1. I don't know how to distribute my correction file settings for DRC-Desginer (Which DRC-FIR uses). I quite like it as for now (version named settings is for now v3.81). But I try to distribute it, I am not very good at english, sorry... A small guide to use the correction file is also written somewhat technically guided. It could be, DRC-FIR users would like my work of filters setting file. Hi everyone that like to use DRC-FIR as DRC correct audio systems. (Settings for 96khz audio systems with very technical correction file) I have in many months tried different settings, mostly changed regulating normfactor as "enemy of distortion" and stage sound creation, the custom settings sound very differently according to normalize filters settings. I have matured the correction filters quite well on my measurement microphone. I have changes Window Exponents to 1.3 as it corrects more extensive to windowed correction filters. I have very had extensive work on equalization microphone correction, but cannot share it because many different ADC and Microphones, you could create your own microphone correction file. I hope you guys would like to check my normfactor settings to DRC-FIR. "DRC Designer" that use DRC-FIR as app source for correcting filters. ( www.alanjordan.org/DRCDesigner/DrcDesignerHelp.html ) If you want to try it out, here is a small guide: Install the DRC-Desginer somewhere, download the attachment file from here "strong96000.drc", copy it to "DRCDesigner\drc-3.2.0\sample" install folder directory (and yes overwrite it), run the app, and record sweep you sound system at 96khz samplerate. Go to "Generate Standard Filters" check only "strong" as the correction file on attachment is configured/written on strong 96khz setting, and you can use your own "microphone calibration file", and click "Generate Selected Filters" and it should process the convolution filters... Wait 6-16 minutes (yes very long time, as it corrects extensively sound, minutes is depending how fast computer is.) When it is finished. Go to "DRCDesigner\ConvolverFilters" folder, there should be a file named "Stereo96000STRONG.wav" that you can use for Convolution - DRC Correction, use it for Foobar (with convolution plugin) or other compatible Convolution enabled Apps or Devices. Try it, it could be that you will very well like the correction file filter. If you like the filters settings I created, try tell other DRC-FIR users to check this correction settings out. Link for drc-fir settings is down here strong96000.drc
  2. I've read that correcting artefacts introduced by converters used to create the sound files is a major MQA selling point, with producers, musicians, engineers involved. How about correcting the target curve used to eQ the monitors in the mastering room ? Nonsense for it requires convolution and much more info than the origami can fit , even if more bits for musical information was retrieved thanks to XXIst century post NyquistShannon maths ? Well, who is talking nonsense ? I yet have to hear differences introduced by MQA, power cords, usb cables etc etc on par with eQ in terms of order of magnitude. Meanwhile, I'm playing with target curves based on good ol' B&K and Harman. Bet both are used to calibrate monitors here and there... I'll be happy to share my REW profiles and findings
  3. Hi I am wondering what the best music server software is and the best digital room correction software to go with it is, please. I have a work system that I plan to upgrade over time. It has a decent buisness PC and a Xindac DAC5 feeding Linn 11L active speakers. The problem is that the upper base can blurr together. I will upgrade in time. I expect to get a Hugo DAC, then amp(s) at least the cost as the DAC, and, say Neat Iotas, then... etc. I love the Naim sound, but if the DAC V1 isn't the greatest, then I wait longer to get my first black box. I am computer literate and have written a Word Macro once, used to know how to update my website and wrote something once in keystroke emulation software that I can not know the name of. So, I'm not a technophobe, but I wont be programming in source code anytime soon. I know that dB is a log scale that doubles every three dB, but I forget the rule of thumb to add two sources together to get total loudness. I don't want the be all and end all, but I can be a bit obsessional about stuff. A mainstream, powerful solution would be fine. I figure I should chose the software to work together. JRiver and Acourate? If so, that's great. It's a pitty HiFi books and magazines give NO guidance about this. I will really appreciate any help!
  4. Greetings folks, I am ready to step into the world of DRC and this is my first foray into anything that require measurements. I am looking at either of a Behringer ecm8000 or the umik-1 usb and plan to follow the steps described here: Creating a DRC Room Correction Filter for your Squeezebox. Basic steps involve measuring L speaker with mic with R line-out from amp into R channel input of soundcard/mixer for the reference channel, then swapping L and R mic/card. I looked up the behringer 302usb and 502usb and it looks to be the most convenient. But I dont know how to use it. I've never used any kind of recording gear before and wondering where to plug the mic and rca-out of amp on it. The mixer has a dedicated mic input socket and separate L+R input pairs. So do I plug in the mic into the mic socket and the rca-out from amp into the R-in of one inputs? Or do I plug the mic into the L input and the rca-out of amp into the R input? Also do you have any recommendations for any other mixer/soundcard hardware that is external and will work with linux without drivers (or has linux drivers for ubuntu)? The whole investment is going to be a one time usage only (or every time I move house once in a few years). Once I am done with it after a week of fiddling with generating FIR files it will stowed away, so I need something cheap that will not auto-sample and allow L+R inputs separately for measurements. If I buy the umik-1 or any usb based mic, I dont know how I will input the other reference channel from Amp, unless there is a cheap external usb box that will work with one usb on mic and another on the usb soundcard. (I hope arecord or Audacity will work with two usb inputs for recording)? Thanks for all your advise. G0bble
