New loudspeakers & room digital correction service - SwissBear - 12-Aug-2017 Hi everyone, I would like to introduce a new service provided by a young fellow in the field of room correction: https://www.homeaudiofidelity.com/ As some might know, I spent quite a bit of time studying these topics of active correction. I started with a Trinnov Amethyst, tried Dirac, then Acourate and finally REW/RePhase. Only this last solution gave me total satisfaction because it allows for making very clean corrections, with minimal phase, easily portable to all players ... May I recall that a well-done active correction allows:
RE: New loudspeakers & room digital correction service - petrik - 12-Aug-2017 Looks interesting. Perhaps I could give it a try although I am quite happy with the filters that I have created with Acourate. Did you get the standard filters or the ones with cross talk correction?

I have got both. I personally prefer the ones with x-talk cancellation. RE: New loudspeakers & room digital correction service - Hifi_swlon - 12-Aug-2017 Interesting idea. I've often wondered if there are people in the UK that specialise in this sort of thing. First thing that springs to mind is it's quite expensive, well relative to the cost if something like Acourate. But then again time and expertise has to be paid for, and it looks like repeat business is much cheaper - which is a good idea. Might get in touch at some point and arrange a sample.

Well, on both my systems, this unique correction technology was kind of a game changer... Two sides to the coin as always:
Having said that, and relative to the price of the systems, the value brought by these corrections largely exceeds its cost RE: New loudspeakers & room digital correction service - Celts88 - 13-Aug-2017 (13-Aug-2017, 08:00)SwissBear Wrote:(12-Aug-2017, 21:58)Hifi_swlon Wrote: First thing that springs to mind is it's quite expensive, well relative to the cost if something like Acourate.

But do you like it RE: New loudspeakers & room digital correction service - petrik - 21-Aug-2017 I received the filters from Thierry yesterday. I have no idea yet does these sound any good but measurements look pretty good. Without filters: With filters: RE: New loudspeakers & room digital correction service - Hifi_swlon - 21-Aug-2017 Have no idea because you havent listened to them yet, or you've listened and aren't sure about the results? Measurements look pretty good, as far as you can tell without knowing exactly what's shown. Interesting he's made a bass slope kind of like the REW default, rather than straight line slope, or B&K type slope. Not saying that's a bad thing - it may well be great I've tried curves like that - just wondered if you guided this decision or it's his default. I'm actually tempted to use him pending your feedback. Sure I could but Acourate and do it myself - and that probably is a better approach long term - but I just don't have the time/desire right now.

I haven't listened to them yet. I'll try to do listening tests during this week. It will be really interesting to hear are these filters better than the other ones that I have created with Acourate. I didn't give any guidelines for the target curve. Thierry said that he usually starts with something neutral & according audio standards. If I don't like the tonal balance, then he will adjust the target curve and create an another set of filters for me.

Petrik I'm also eager to hear your thoughts on the filters, when you get the time. I haven't done any measurements yet with REW, and really don't think I would do it justice, hence why I'm willing to pay the money for Thierry to do his magic on it. Thierry had mentioned something on the New Loudspeakers & Room Digital Correction Service computeraudiophile thread regarding house curve Pkane200 - Will you be able to accommodate a house curve, and if yes, in what format? Thierry - Our goal is to propose the optimal filters set by default. But if you have some preference in terms of tonal balance we can adapt to different kind of house curve format (text file, picture) The process is to start by our proposal and iterate if it is really mandatory Pkane200 - Thank you. I would definitely want to start testing with an optimal, flat filter. But, my experience flattening the frequency response did not produce the best results. A very slight house curve (a few dB bump below 70Hz and a few dB gradual roll-off after 5KHz) made a big difference. I'll do some measurements and contact you to do a test with a sample track. Thierry - Just to be clear when I said "optimal" I didn't mean "flat" : as you said optimal refer more to what will sound natural in your listening environment. Looking forward to your measurements!
