Hey Brian, I want to thank you directly for recommending Focus Fidelity. In response to todayās Paulās Post, I placed this comment:
This whole series of Posts has coincided beautifully with my first experiments using DSP room correction software. About two weeks ago I followed the advice of someone in the PS Audio forumās new Rooms & Treatments category(something I suggeted to Paul McGowan to add and surprisingly he thought it was a good idea), bought a measurement microphone ($100) and software for measurement (free) and filter-generation ($250) from Focus Fidelity. There are certainly MUCH more expensive options for this, but FF is in my budget and a huge shout-out to David there who answered my newbie questions and recommended a fantastic book to help explain the whole procedure.
The general philosophy behind this is that your room - whether itās a bedroom, family room, outhouse, or dedicated isolated listening room like mine, has unique acoustic characteristics that WILL change how your system delivers music to your ears. Sounds like EQ, right? But itās a lot more than EQ. It makes many of the assumptions Paul made when he said in this Post, āSome designs simply canāt reproduce spatial information wellāeither because their off-axis response is uneven, or because they smear phase and time alignment.ā Just like speakers, rooms affect these characteristics. Whatās more than EQ is this statement from the intro to the book: āthe goal is to accurately reproduce music as close as possible to the content on the recording.ā ( Barnett, Mitch. Accurate Sound Reproduction Using DSP, p. 6). So itās not ācoloringā sound as much as doing what it can to reproduce what the engineers and producers heard when putting the recording together. The author is singing my song because he has great experience on BOTH the recording and playback sides.
So last night with great anticipation and a bit of nervousness, I plugged the digital filters into Roon⦠and⦠I was amazed. From the get-go, I noticed that I lost no detail, but the detail was more homogenous with the overall sound. The center-channel features - vocals, instrumental - are still there, but better mixed, less āedgy,ā a bit softer. Itās funny, but in another Post I was saying how my ears had to get used to that center channel being so pronounced when I first started listening in my room a few years ago, but now I think they might have to adjust to NOT softening the center channel so much. The soundstage is every bit as wide, but central to this Post, DEEPER and more 3-dimensional. And reading the suggested book, I see how it has a lot to do with time accuracy. Not just in the center, but all across the stage, things were immediately deeper. As for definition, I need to listen further, but nothing has been lost.
So the reason I replied to you [pmj in the Post] is to use your list:
1 phantom center.vocalist - BETTER
2. the singer is in the room and the speakers disappear - BETTER
4. the soundstage is 3D and is beyond the width and depth of the speakers - BETTER
5. 4. I am transported to the venue - BETTER, except there were no glasses clinking.
Again, thanks for the recommendation. More experimenting to come, but I think this might be the best single improvement Iāve seen since building the room.
