The mains were clear, crisp, and well integrated. We evaluated the imgaing with some pink noise and confirmed what we already knew, they were setup to image proper. I was particularly impressed with the vocal clarity of the center. It was really spot on IMO. I'm really picky when it comes to dialog but the Meridians sounded nice.

Measurement Comments: The room has come a long way both aesthetically and acoustically. The ringing was significantly lower this go around as evident in the waterfall. The problem areas in the sub FR are room related confirmed by coincidence of major group delay swings at the sharp dip frequencies. Every bit of bass trapping will pay major dividends for those areas. I do wonder though how they(subs) would measure with the mouths on the floor or one mouth up and one mouth down...... Maybe next trip!?

Overall Nice Job man, cant wait for the Next time!

Hey Nick. What software/adware do you use for your measurements? And do you do acoustic analysis professionally? It certainly sounds like it judging by your knowledge base. It will be a great learning experience to see how JD will acoustically treat the room to smooth response. Thanks to both of you for sharing the process!!!!

I attached a doc that has been shared over on the Audyssey thread. Basically you play pink noise through two speakers. The sound should image directly center between them if distance/phase/level is set correctly. For example playing pink noise through the L and R, the noise should center between them. Adjusting the distance setting on one or the other will shift the image if it is not properly centered.

I am by no means an expert. I use REW(software), external sound card, and mixer, and a calibrated microphone. All this is run to a VERY modest laptop. The software is freeware and if you dedicate some time anyone can learn to use it.

Nick, which calibrated mic do you use? Im still getting the hang of REW but have OM as well for a quick measure. It truly is a nice n easy way to get a quick idea of what your system is doing and confirming measurements with REW, the mic is pretty close to spot on.

I was always planning to add some bass trapping but I didn't want to do it until the room was measured. The way I see it if you don't have data how would you know if you helped or hindered?

Hey, everybody! I just wanted to let you all know that I'm still alive and kicking! I appreciate the texts and facebook nudges asking about progress and my welfare! biggrin.gif

It has been 3 weeks since Maker Faire:NC and I just wrapped up the last of my official business / obligations for 2012. 2013 planning starts soon though.

I have been busy every weekend with birthday parties, camping trips, cleaning house, working out of town, etc. etc. and it it feels like I haven't had a chance to breathe. I sat down on Sunday night and started playing with XBMC and I'm totally sold. I think I'm going to save up for a Mac Mini to install as a dedicated HTPC running XBMC.

So... theatre progress: none. Feel free to blame the projector hanging (hangs head in shame) but I have been seriously busy with life too. tongue.gif

I have the part 13 video footage in the can but I'm only just starting to edit it. I'll try to get that out some time this week. Theatre Status: functional but not "done". We've got a couch, we've got sound and video, we've got snacks. biggrin.gif

My to do list (in no particular order):
1. build and wrap frames for screen wall
2. design and build rear wall decorative piece (see draft below)
3. build and wrap absorptive wall panels (Spoonflower-printed)
4. install bass trap behind screen
5. install molding between ceiling and soffit
6. drywall / cover up the hole where the heater used to be
7. paint closet door in rear
8. paint rear wall where decorative panels aren't going
9. replace carpet on stairs
10. reinstall bannister on stairs
11. finish painting stairwell
12. install sconce light in stairwell
13. fill with sand or replace door at top of stairs
14. replace exterior door to left of stage with solid door (no window)
15. design new air vents, cut, install on ceiling
16. design and print can-light inserts for soffits
17. touch-up drywall, paint
18. buy and install rear channel speakers (can I find a single DSP 5000 somewhere!?)
19. save for and install Meridian HDMI switcher and upgrade to lossless audio

Draft of the rear wall decorative CNC-cut MDF:
406
This is a 4 x 16' x .75" MDF carving that I'm going to do on the ShopBot CNC. Design will change but you get the idea. Not sure what color I'll paint it.
post #938 of 1281
Wow - that's all - how about in your spare time?? smile.gif
Really like that design for the rear wall!
post #939 of 1281
I like the slight downhill angle to the overall curve pattern - very nice touch! Looking forward to more updates and your next video!

Thanks! I wanted to vary the carving depth as the wave moved. We'll see...

OK, OK. I admit it. Progress has been halted because I hung the projector. We are down there almost every night thoroughly enjoying the room! I know that I owe you guys a new video and some pics of the painted and furnished room. I'm going to try to knock that out RealSoonNow.

I did somehow manage to find time to assemble a kick-ass XBMC Home Theatre PC! I've had AppleTV served by iTunes all around the house for a while but I really wanted to stream uncompressed Blu-ray rips and experiment with a new user interface.

The XBMC user interface is very good. I am amazed at the power of the software. You can install scripts and plugins to do all sorts of things. I installed plugins for browsing all kinds of free streaming networks (ABC, Hulu, HGTV, ESPN, DIY Network, &c. &c.).

For hardware I took the cheater's way out. I bought a base Mac Mini and upgraded the RAM to 8GB from the standard 2GB. I added two 3TB external hard drives for local storage rather than installing a NAS. I currently have about 350 of my personal DVD rips, a half dozen of my personal Blu-ray rips, and about two dozen TV shows ripped from my DVDs on there. And yes, I own all the original discs! :-p

If you haven't tried XBMC I highly suggest checking it out.
post #943 of 1281
How do you control the XBMC program on the Mac Mini? Is it through an iPad or an Android device? Or can it operate via IR with a normal remote (up, down, left, right, enter, etc.)? I've always just used physical media and I know I have a lot to learn on putting together a nice streaming content system....that can be easily controlled by an AMX, Crestron, Savant, etc. It would be nice to see how your XBMC setup came together.
post #944 of 1281
Are you running XBMC Live or running it on top of another OS?

That's a great question. I was very concerned about control and it turns out that it's very capable. Out of the box XBMC will respond to an
  1. Apple remote (U,D,L,R,select,menu,play/pause)
  2. Keyboard
  3. HTTP (it has a built-in web page but also will accept HTTP commands via Crestron, AMX, iPhone apps, etc.).


Currently I'm controlling the XBMC using an iPhone app called HippoRemote and a simple Apple bluetooth keyboard.

I'm integrating a module to control the XBMC via HTTP through my Crestron system. That has lots of advantages because I'll be able to have direct access: browse titles, see cover art, etc. live on the touchpanel instead of monkeying with up,down,left,right, etc. commands.

XBMC wasn't very hard to configure once you wrap your mind around how it wants to work. I used Apple TV for years with a Mac running iTunes 24/7. That has disadvantages like the lack of file format support (no uncompressed Blu-ray rips, etc.) and, frankly, I don't like the user interface as much as the XBMC.

Good question. I'll explain for everyone's benefit too.

XBMC is free software that can run one of a couple ways:
  • Just like any other program on a suitable computer (supports Windows, MacOS, and Linux)
  • XBMCbuntu on a suitable computer

XBMCbuntu is an all-in-one solution that can install on inexpensive hardware and it just works out of the box. This includes the operating system and XBMC.

I chose to run Mac OS X on my Mac Mini but set it up so that XBMC is started automatically. There's really no reason why anyone in the family would ever have to know that XBMC isn't just an appliance instead of what it actually is (a program running on a computer). I like being able to have a full computer down there so I can do other things (web browse, Netflix, Pandora, etc.) that XBMC can't currently do.

Great info. Thanks.

Thanks for the info! I have a full-blown AMX Netlinx system that I am dumping in the coming months and replacing with a Savant System (www.savantav.com) which uses a Mac Mini for "the brains" of the system and is highly integrated with all Apple products. In fact, Savant is one of the few companies blessed by Apple as a preferred partner.

I would prefer IP control, which is close but still a bit different from HTTP. I'd love to talk with you about this part of your system set-up sometime or even road trip with some cold craft beer in-tow to see how an automation expert really puts one of these together without the restrictions from iTunes.

My primary remote will be the Savant SSR which is essentially an iPod Touch welded into a configuration with hard buttons. After your post above I have every confidence my future Savant system will be able to work with a streaming set-up like yours. I am willing to live within "the box" and kiss the king's ring when it comes to complying with Apple's interface, but as you pointed out - that doesn't do anything for all of the other files I have, including any potential full-res lossless Blu Ray rips so I am actively looking for another solution. I also came across the Popcorn Hour C-300 as a potential device and someone else had recommended the Dune HD Max. It's very confusing when you don't know all the pros and cons of all these different streaming devices, including control options.

Here's a link to the Savant remote in case you haven't seen it: http://www.savantsystems.com/product-details/savant_select.aspx

Here's a link to the Popcorn Hour C-300 device. By the way, I called them and these are HDMI 1.3b devices with 1.4 devices on the way later this year or early next year. As a consequence they cannot do 3-D streaming at the moment: http://www.popcornhour.com/onlinestore/index.php?pluginoption=catalog&mainItemId=47

Sure, no problem. Hopefully it will be useful for you. I'm learning a lot about the control side of things.

I'm using MKV containers generated by MakeMKV on the Mac. I like the "one-file" approach. I could compress them through Handbrake but I don't like what it does to the picture quality.

You are right about the ceiling I painted mine Tricorn black flat Sherwin williams color since the Mrs works for them... I primed it and it still took 2 coats. Love the videos

I've heard great things about Savant although I don't have first-hand experience. When I said HTTP control I really meant IP control. I'm pretty sure that the control uses TCP (might be UDP not sure) so, for Crestron, you can just use a native socket in Simpl+ or a TCP server object in Simpl Windows.

I know there are huge fans of the Popcorn Hour out there. Again, I don't have first-hand experience but I remember that there were a couple deal-killers for me. The user base of XBMC is huge and it's a mature product with lots support available. No matter which system you go with you still need to work within its constraints (file types, file hierarchy, naming conventions, etc.). I found that XBMC was the most flexible so it won. biggrin.gif

Thanks for the compliment!

It seems like you can't put enough coats of black on the ceiling! I gave up after 2.5 (when I ran out of paint)! Looks fine. Everyone that comes in there just sees the giant screen though so it doesn't matter too much!

Lol ill tell you one thing.. Dont put no florescent bulbs on it because it will make you go nuts... Thats why I kept painting it because that was the only lights I had down there at the time

^^^^So you are saying the best way to get paint coverage that you are happy with is to paint in the dark? I LIKE it! wink.gif

I actually worked on the theatre yesterday!

I went out to TechShop and built five frames to surround my screen and rack. I used the same 1.5" finger-jointed primed pine that I used to build the screen and screen wall. I'll post some pictures later.

I LOVE the Kreg jig! Someone at the shop asked me why I didn't do half-lap scarf joints instead of pocket screws... I was like - {blink} {blink} - "because I wanted them done today?!

I've also been playing around a LOT with the XBMC build. I installed the Cinema Experience script and have been amusing/punishing my family with "Let's go out to the Lobby" videos, THX trailers, and other movie-theater-like pre-roll before I'll let them watch a movie.

Remember this one? They put it on Youtube in 1080p! Perfect!

We watched Transformers: Dark of the Moon on Friday night and it was pretty cool! Those two micro-sized transformers annoy me, though. They are the Transformers equivalent of Jar Jar Binks.

Looking good! What skin did you settle on for XBMC? I planned on spinning my own, but after trying some of the usuals I realized the family didn't enjoy all the flash. And as a result didn't want to use it. So I currently settled on Quartz. I'm pretty sure I can convince them it's just another Apple TV with it rolleyes.gif.
post #959 of 1281
I know what you mean about all of the little "pre-show" videos. I took that same Regal one and cut out the very beginning and end to get rid of the "Regal Entertainment Group". Now I show it before every movie.

My sister saw the "Birthday Party Rooms Available" though and now insists that she can invite all of her friends over for a movie and I have to serve them cake just like at the "real theater".....

I'm using Aeon at the moment. I really like the eye candy of the fan art for movies and tv shows. I've spent a fair bit of time customizing the main menu so that the family's most-frequently used things are available without going more than two menus deep.

The BlueCop Amazon Prime plugin is excellent as is Free Cable. I wish that there was a functioning Netflix add-on but, hey. I can't have everything!

Haha! Busted! Now you're required to have birthday parties there! I edited out the opening few second of that video too. I love it when friends see it and say "Hey! I remember that roller coaster from high school!" Loads of fun. biggrin.gif
