I have done my utmost to make sure this program functions correctly, including testing on several machines, virus-scanning the archive before posting it, etc. I don't expect any problems, but please keep in mind that you use the tool at your own discretion.

Feel free to email me with any bugs, suggestions, or requests. My email

At the suggestion of a forum member, i've added a paypal email for donations.
If you feel the tool has helped you out and you'd like to support further development, you can paypal any amount to smith@kulkarnicorp.com. Thanks

It ran on my Vista Home Premium with Intel duo 2 core 6750 running at 3.2 GHZ with 2 Gb ram GTS8600 GPC, Raptor HDD, in the versin you now have on the thread.

This is a really neat app. Would be cool to develop further into a home theatre design tool so you can picture how things will look in a planned theatre.

1) I can't set my front tower speakers on the floor. They won't go any lower than your 4" limit off the ground! I can't use this like that, so I shrink my speakers 4" as a compromise.

2) My speakers are toed in quite a few degrees. Any plans to accommodate toe angle?

3) The screen doesn't look like it can go flush with the ceiling. That's how it must be in my setup. Not key for first reflections actually, and probably has nothing to do with it, but I just wanted to see how it looked in here

4) Any plans for surround/rear speakers?

I am only a reader here, but some of your questions were answered earlier in the thread

1) distance is to middle of speaker

2) sound field generated by speaker is usally large enough where toe-in will not matter in calculation. Jeffrey gives an example as to why in a earlier post.

3) screen is transparent

4) Jeffrey's research shows that reflections from rears are not an issue. See earlier posts.

Ok, fair enough, but how can it be the distance to the middle of the speaker when my speakers are 39" tall and the thing bottoms out at 4"?

If your speakers are 39" tall the mounting height is 1/2 of 39 or 19.5" therefore the bottom of 4" is irrelevant With that mounting and the size of the speaker input, the software should see the speaker as if it was standing on the floor. Although I see in the graphic that the speaker is still floating above the floor.

For the moment I am going by Jeffrey's statement that the height is to center of speaker and that the software would then calculate the reflections for your setup as though the speakers were sitting on the floor.

Maybe I misunderstood him earlier.

Since I do Mechanical Engineering with Autocad and numerous calculation software I have seen over the years that what ever is shown graphically may not reflect what the calculation is actually doing.

Hi everyone,

Great app, I ran it on vista premiun works great!

I just wanted to ask a few questions:

**if my speakers are divided like half the size (bottom) is only the wooden box and the top half has the actual drivers...
should i measure the whole wood box or just the part that has the drivers in ?

**is it possible to "toe in" the speakers ?

**why can't I see the reflections behind the speakers?
i've read some material on the web, that says acoustic treatment should be made at the sides of the room and behind the speakers
first, because these are the most problematic areas.

thanks,
tomer.

THis is a great program...Installed it ran it. LOVE it.


Now more importantly what does it mean

How can I tell the distance of my reflection points so that I can place my sound absortion boards in the correct positions?

Also is there away to cut and paste the picture....is there a "save as" feature? I guess I can use Snap IT and just screen capture the pic and post on my build thread.

Again, Awesome piece of software. Where do I send a donation?

When you measure:

offset of side speakers from side wall -- where do you measure to on the speaker (the mid point of the speaker -- or the closest part of the speaker to that wall)?

height of side speakers off floor: do you measure to bottom of speaker; or top; or in the middle?

when you measure off-set of speaker from front wall: do you measure to the front of the speaker; to the back of the speaker or the middle?

What exactly is the width, height and depth of a listening position? I have no idea what measurements are being asked for here.

I have 3 chairs in my front row. The chairs are a total of 10 feet wide. But what about the "height of the listening position" and how does that differ from the "height off the ground"? And what is the depth?

Can someone explain EXACTLY what is being asked for here in the listening positions? It is not clear.

Also, iIs there any way to make fine adjustments on the sliders. When I need to go only one inch, I can't get it to do that.

This software no longer seems to be listed on the page referenced in the first post. Did I just miss it or is it available somewhere else?

Thanks

I'm having trouble with the links in the original post.

Hmm. It doesn't seem to be available. Is there a way somebody can send me that file or someone can host it please?

Thanks! I could really use that program! It looks amazing.

I'm with the fellow bumpers on this post. I'd like to take a look at it and have been watching the posts for a while. I wish I had downloaded it earlier, but I'm ready now to really start checking out my speaker layout and don't have the software!

That looks like it works for me. The program runs (after I downloaded the DX9 patch thing), but I haven't tried calculating reflection points yet. If I got that far, I'm sure the reflection points calculation will work. I'll verify tonight. Thanks!

Edit: It works great!

OOPS...
As I was saying.... works.
When the user starts adding crappy software that has not been debugged (read... software vendor releases to general public to debug FOR THEM), the OS/machine WILL have problems.
I worked for Dreamworks Animation for 6 months and they were running photoshop on G5's. An animator would walk away from his station and when he came back the machine would be locked up... NOTHING HAD HAPPENED IN BETWEEN!!!
Consequently, my PC's at home (4 online weather stations, 2 doing SETI calculations) will lockup occasionally as well.
Bottom line... I grew up a PC person, and desire to stay, but If I started with Apples, I would probably stay apple as well...
Personal preference and familiarity!!!
GET OVER YOURSELVES!!!

Is there a way to zoom into the room so the grids used for measurement can actually be "measured". I know the program is not the be-all of reflection point calculation software, but I think its great and a zoom would be wonderful (unless of course its always been there and Im doing something wrong?)

Do any of the users have answers to these questions. I am assuming that you measure everything from the middle of the speaker. Good assumption? I also don't understand the the difference between hight off the ground and height of listening position. Would appreciate any help.

Generally a great program. I hope that Jeffery found that great job and will eventually return to this thread. In the meantime help from anybody else would be appreciated.

Won't work for me. My room is 26 X 21 but the theater is only in a 13 X 21 portion of it. This assumes everything is centered. I need to move everything over and have a big empty space to the left. Oh well.

Jeff,

Nice software!

I can't save or load rooms without it crashing, but it otherwise works.

It would be cool to add a toe angle to the front L/R speakers.

Thanks,
Dave
