First Reflection Points

* Language: C/C++
* Graphics API: DirectX 9.0c
* Download Link: Download Here (Requires DirectX 9.0c and XP)

This tool was originally written to aid some friends in the design of their home theatre. The idea is to locate areas of wall/ceiling where sound from the front speakers can bounce and reach the listener's ears. These "first reflections" arrive at the ear slightly after direct sound from the speaker, since they travel a slightly longer path through the room. They result in a smearing or muddying effect on the sound. Special acoustic dampening material can be placed on the walls/ceiling at these locations to absorb the sound and prevent it from reaching your ears. I released this tool to the home theatre community on www.avsforum.com. It has been downloaded approximately 1000 times as of June 2007.

The GUI elements were written from scratch using some of the nice new functionality in D3DXSPRITE. The reflections are solved using my voxel accelerated raytracer described below.

In the screenshot above, the splotches of color on the walls correspond to these first reflection zones, color-coded by speaker, and each should be treated with acoustic dampening material.


edit: I agree, broken link, I have the software but since I did not write it or have permission from the author I can't zip it to you, sorry, I respect the IP of the author.

My work must have a firewall up for that, anyway glad it's still downloadable to the avs community.
All I get is a 172k file that does not load anything, not like my prior app

Too bad this doesn't work any more.

Tried to run the DirectX patch, no luck.

Should have been written for the Mac. That way it would actually work.

I'm not sure Mac people should be throwing stones about backwards compatibility. Aside from that holy war, this seems to work fine for me. I'm running Vista x64.

I got it to work by right clicking on first102.exe, going to the compatability tab and choosing windows2000. Now it loads up fine for some reason. Wish the author didnt fall off the map .

I'm running XP sp3.

Does anybody have any idea what happened to the OP/developer? The software lists the author as "chris.smith@pcrx.ca"... Google turns nothing up, but the site was down after mid-'08. His profile says his last activity was 10-09-07 09:09 AM. FRV is an awesome tool and I wish the developer was still around. I hope nothing happened to him.

I believe v1.02 was the last/latest.

Cheers,

Can you ask your brother for permission to post the updated version? Or if he has time to post an working version the community would greatly appreciate the support.

Thanks.....

Hi Timmy. We've already had the discussion about rotating speakers and the fact is rotation doesn't make much of a difference when it comes to reflection points since the app casts such a wide cone off each speaker anyway.

Re small group or wide group...if you mean listener zones, the smaller the better. The smaller you make the green boxes, the less sound will reflect off the walls and hit them, resulting in smaller clusters of points, so you get to make less panels!

As for the past few posts about feature requests, I will consider all of them for future releases, but for the next version, which will be 1.1, I have now locked in the features that will be available. They include:

1. Cathedral Ceilings
2. Ability to setup speakers off-center in the room x-axis
3. Ability to setup listener zones off-center in the room x-axis
4. Ability to selectively disable listener zones
5. GUI redesigned to support these features
6. Sound now passes through listeners to back wall and reflects, resulting in
more reflections shown on back wall. Before I was assuming the green boxes intercepted all sound fired at them, which won't strictly be the case unless you're a family of fatheads.

behind the scenes improvements:
Raytracer now 2x faster than v1.02. Default scene on my machine is < 5 seconds. Can't make it much faster.
GUI drawing code is 3x faster
CPU utilization down 15% on my machine

I'm not sure when this release will be since I will be away most of the next month, and I am only about 1/2 done the modifications, but i'll do what I can.

Is it safe to assume a newer version was never released? The zip I downloaded contained version 1.02 but has none of the features listed by the author. Any word on the status of this software?

Yea - having all those updates would be cool, even though I'm "done" my brother and brother in-law could use the new release....

Haha, good one Mike.

I don't know about the mirror trick not being enough, I've got all the points either already absorbed or marked with painter's tape anyway. But I'm suggesting it to others so it'd be nice to have an up to date version. I like it if for no other reason than it reminds people that they need to consider the ceiling and floor! Although now that I think of it, it's not showing front wall points either, much less rear wall. But it's the only tool I've ever seen that is meant for a large seating area rather than a one-position situation such as an audio control room.
