You didn't miss at thing.  In fact, what you pointed out was an oversight on my part.  I'm not sure why the look angles are set to 20 degrees.  If you have insight into why this may have occurred, I'd appreciate any input.  This may be a default when not using the Head Tracker - although, I thought the default would have been set to 30 degrees.  I took the measurements with LOOK ANGLES:AZI and I don't recall having to enter a look angle value.  I'll have to redo the PRIR when I have a chance.

Thanks for trying out the PRIR and for pointing out the look angle setting.

The look angles have to be input as part of the set up for the emulation. Page 26 of the manual I/O ASSIGNMENT AND ANGLE ENTRY. I only brought this up because the image seemed to move a little as I moved my head. This usually doesn't happen with the head tracker. Thanks for down loading your PRIR.

Thanks for the tip on the ANGLE ENTRY.  Good to know for anyone taking measurements without using a Head Tracker (HT).  I had to reset L/R and Ls/Rs to conform to ITU the spec.

 

Seems odd that you are getting movement when you move your head.  For me the image is stable. But I did notice after the measurements, when I first connected the HT, the center image shifted a bit to the left. I had to slightly adjust the angle of the transmitter on my headband to zero it in on the receiver.  Once adjusted, the image was centered and stable.

@jackhamm,

 

I've uploaded a PRIR with the corrected look angles to folder - Home - B&W 804S 5.2 with Velodyne DD18 Sub (near-field corrected).  Also added a second virtual sub to this PRIR.  First time I've tried multiplying a sub using the AVG LOOK C: 2* process described on pg 58 of the User Manual (for firmware dated 3 August 2011).

 

In essence, what the Realiser has allowed me to do is transform my 2.1 stereo system (valued at $8,100 retail) into a 5.2 home theater system with a retail value of $18,000.  Not a bad ROI for a less than $3K upgrade.

Thanks jazzfan, I'll give it a listen as soon as I get a chance.

Jazzfan, The new PRIR sounds great. I get a more stable center image that doesn't move when I turn my head. Dont know if thats due to revised Angle Entry, but it seems to make a difference. Very detailed presentation. Thanks for downloading your PRIR.
Regards

Hi everyone,

 

I did an interesting experiment today. I have uploaded the two PRIR's from today's measurement session: "Dropbox/Darinf/Magico Enigmacoutics Super Tweeter"

 

I was testing a new product: http://www.enigmacoustics.com/prod-in-finale.asp?idno=92

 

I first heard this super tweeter at the Newport Beach Home Entertainment Show. Their demo just blew me away. Once they hooked up the super tweeters, the Magico speakers sounded SO much better.

 

So I was curious to see if the Realiser could pick up the difference between using a super tweeter or not. It goes all the way from 10Khz up to 40Khz

 

Fortunately they sent my friend a pair to demo, so took them to my other friend with Magicos to see if the Realiser was sensitive enough to pick up the difference.

 

Let me know if you can hear the difference.

Here's what's in the read me file:

The actual system measured is pictured here:
 
I generated a 7.1 PRIR from their 2.0 channel system.
 
There are two PRIR's. One is with the Sopranino super tweeters and one is without the super tweeters.Can you hear the difference?
 
The difference with and without them on the actual system was dramatic to say the least. The super tweeters added tons of detail, air, transparency, imaging, etc. I was truly impressed on how much better the $40,000 Maigco's could sound!

Hi Darin,

I read about these super tweeters earlier this year.  I thought they were interesting, but I dismissed them because of the cost.  Thanks for giving us the opportunity to listen to the tweeters with the Magicos (it's great that we can do this with the Realiser).  Unfortunately, I haven't tried your PRIRs yet.  But I will after this heat wave breaks - we don't have AC so I haven't been listening to headphones at all.  I'll give you an update next week.  Thanks again for sharing!

For the hot weather, I use CIEM's so my head doesn't get hot.

 

If you have speakers with a dynamic tweeter, the I would seriously try to audition the Enigmacoustics Sopranino. It's not cheap at $3700, but for the right speakers, they could be much cheaper than upgrading to better speakers.

 

Anyway, I am not very confident that the Realiser can pick up the difference with and without the super tweeter. I was going to wait before commenting on my perception, but I am not sure what went wrong with my measurements, but to me, the PRIR's sound VERY different even though I used the same mic insertion to do the measurements with and without the super tweeter. In theory, the difference between the PRIR's should not be that significant. There must be something else influencing the measurement.

 

Now that I think of it, there was some "tube noise" coming from the preamp which the owner said was due to a tube starting to go bad. There was nothing I could do to fix that at the time. But I figured the noise would be the same for both measurements. Perhaps the noise was higher or lower for each measurement.

 

I don't think the PRIR's are a good representation of what I heard.

I do not own a Realiser (some day...), but I have been reading up on it quite a bit and had a thought I wanted to run by those with more knowledge and experience: when I am travelling, I am much more likely to use IEMs than supra- or circumaurals for ergonomic reasons. I realize it wouldn't be possible to put the Smyth mikes and IEMs in at the same time, but wouldn't it be possible to create a mold of one's ear canal with one of the DIY CIEM mold kits and make a replica of your canal (with materials that are similarly absorptive to the tissues in the ear) and create a PRIR suitable for IEMs?

I know it probably wouldn't be easy, but depending on the materials needed for the replica, you might even be able to find someone with a 3D printer to make them... Anyway, if this is a crazy idea, let me know and I'll go back to wearing my tinfoil hat and muttering to myself. tongue.gif

Actually, I think the "Smyth Realiser READY FOR PURCHASE" thread is the proper place to ask this question.

 

Also, I don't use IEM's so I'm not really qualified to answer from firsthand knowledge or experience.  But I believe that when using IEM's to listen you do not need to use an HPEQ file, which is the second file utilized by the Realiser when listening through external over-ear headphones.  The HPEQ is only required when listening through external over-ear headphones, and is created by having the microphones inserted in your ears and then putting your headphones on, over your ears with the microphones still inserted. That "measurement" process produces the HPEQ (corresponding to a specific external over-ear headphone/amp and your own ears).

 

The listening environment itself is "measured" through microphones inserted in the ears WITHOUT HEADPHONES OR IEM'S INSERTED, and produces a PRIR file, which is the first file utilized by the Realiser to duplicate that listening environment for playback/listening through a Realiser preset.  To complete the playback/listening preset an HPEQ is selected if using external headphones, or no HPEQ if using IEM's (i.e. only the PRIR is needed when using IEM's).

 

In other words, the PRIR required for playback/listening is required for any type of listening... either using over-ear headphones or IEM's.  And the creation of that PRIR is done simply with microphones inserted in your ears.

 

The HPEQ required for playback/listening is only for over-ear headphones, but is not required when using IEM's.  So there is no issue such as the one your are concerned with if you're going to be listening through IEM's, as the preset only consists of a selected PRIR.

Hi guys , I just found some French PRIR club at http://www.smyth-realiser.fr/?t=fichiers_salle with interesting setups to compare. Registration needed unfortunatly I don't speak french maybe someone of you can.

You can use "Google Translate" and get a good idea of what is on the website:)

hello,
early December, I go to Paris at av-in (french dealer of the realiser) to configure my realiser with my fostex th900. I'll tell you more how  to get the prir of the club. Loïc

post #345 of 350

So I sold my O300's for good money and "downgraded" to Neumann KH120A for desktop.. uploaded few PRIRs to Hekeli/Home.

 

I will make some 5.1/7.1 later with my SVS PB12-NSD sub. Going to position, tweak and measure to try to surpass my old trusty Siba 8260A PRIRs for movies..
