Ohm Walsh Micro Talls: who's actually heard 'em?

Mapman to answer your questions. I used the recommended USB microphone: UMIK-1 and bought a USB cable extender so it could reach around my room. I used the stereo version of the software (they make a home theater / more channel version) which is around $430. It is expensive, but there is no other product that is going to what Dirac can do acoustically for the money. But I would say if you can swing it even after getting Dirac get acoustic treatment in conjunction with Dirac. Dirac can only fix so much including room nulls.

Nice!


I like the overlay of target, before and after measurements! I’m noticing the target is not flat response. I’m guessing that is because software attempt to compensate for non-flatness of human hearing. Just a guess?

Did you attempt any nearfield measurements with the OHMs ie measure them with room acoustics minimized? Just wondering what that would look like.

What’s is your assessment of the results after Dirac versus prior from a non technical music enjoyment perspective?

Very interesting stuff. Its a software only (no special hardware required besides microphone) significant tweak for sure as measured for the cost. Nothing grey or left to uncertainty from a technical perspective there.

Very cool!!!! Affordable software only tweaks like this are just another reason to like computer audio.

Hey guys .. a while back I posted about Amarra Symphony and its Dirac component (iRC).

At the time there was no Dirac stand-alone option for OSX and Amarra Symphony was it. It's fantastic software and if you are new to room correction you will be pleasantly surprised with the ease and flexibility it offers, never mind the great sound. Another recommended mic and the one I use is the XTC Microphone Pro. Highly recommended.

I use Plex and other apps on a PC so standalone option would seem to provide the flexibility I need. 

I've added Dirac to my wish list.....

Mapman,
As I said in an above post I have boosted the EQ curve to be tilted towards the bass. I tend to like this sound as it sounds a bit more reinforced on the low end.

Dirac, by default does not use a flat curve. it is +2 db in bass and -2 db at the treble. According to their research most listeners tend to dislike a flat response as it sounds thin due to the fact that our ears don't heard evenly. As I have said I bump the curve a bit more as I prefer that sound. Other manufacturers like Audio Source who make numerous equalizers has the exact same position about flat frequency response. However you can make the EQ curve flat if you so choose or really anything.

Dirac will let you set a target curve any which way you like and will tailor the response according to the target curve.

I have never done nearfield measurements with the Ohms.

Listening to Dirac in my room provides a couple of cool things. First listening becomes more fatique free, imaging becomes less blurry, and the overall presentation is more natural and spacious. You also tend to hear more information in tracks as things seem to be presented in a more even handed manner. Certainly worth the $500 price of admission after you purchase a calibrated microphone.
