Re: Cheap, Makeshift Parabolic Dishes?
Do the dimensions matter? i'm seeing a lot of shapes and sizes... are there simple rules-of-thumb that people use?

Re: OPA-Based Binaural Head
My apologies for the huge file size, I¡¯ll keep that in mind for any future posts. I do plan on adding ears to it so hopefully that will aid in ?generating something approaching an HRTF.

Re: OPA-Based Binaural Head
This sounds like a decent, dry stereo recording, did not feel any "binaurality" which you get if recording live in your own head with Roland CS-10EM. Much better results I get from a piece PVC tube

Re: Cheap, Makeshift Parabolic Dishes?
I made one from my neighbor's discarded parabolic heater that he bought at Costco. The rest was easy. https://www.google.com/search?q=Parabolic+heater&sca_esv=582945116&tbm=isch

Very cool! If you could please, though - please avoid sending huge .wav files to the group. Thanks, -Scott

OPA-Based Binaural Head
Hello, Been lurking this group for a while and finally got around to actually building something! About 2 years ago I had some extra MDF lying around so I decided it would be fun to make my very own

Re: K87 capsule with isolated backplates
True Chris, we tend ti diverge on topics. Short answer is there are no inexpensive K87 style capsules I know of. Most are single Backplate. You are right that it is engineering. Precision engineering

Re: K87 capsule with isolated backplates
Thiersch has been re-diaphragming Neumann capsules for decades and I have never had to reject a capsule. It's far from art, it's pure engineering. Anyway none of this has anything to do with what I

Re: K87 capsule with isolated backplates
I agree with Matt on this one. Rebuilding capsules is an art more than science. I know of people that do this. It is on par (although easier) with rebuilding a car engine. The current capsules made

Re: K87 capsule with isolated backplates
Matt's capsules are great. I have used the RK87 and the RK12, and they sound beautiful. Another option may be from Arianne Audio: https://www.arienneaudio.com/. 47 Flat is great, but I haven't

Re: K87 capsule with isolated backplates
Hi Matt, having a non original capsule massively devalues the microphone hence the reskin, which doesn't. I've been doing microphone repairs a long time and Thiersch return capsules as good as the day

Re: K87 capsule with isolated backplates
We sell RK-87s as an *upgrade* option to many U87i / U87 Ai owners (and TLM103 owners too).? The cost of an RK-87 is likely to be significantly lower than the cost of refurbishing the Neumann

Re: K87 capsule with isolated backplates
JLI has some 47's. Not sure if that'll work for you. I didn't see the 87's, but I just did a quick search. https://www.jlielectronics.com/microphone-capsules/# wrote: -- Sean O'Rourke

K87 capsule with isolated backplates
Hi Everyone, I have been asked to temporarily fit some K87 capsules to some U87's while their capsules are refurbished. Can anyone recommend a cheap source of good K87 capsules with isolated

Re: capsule array self-noise
A larger capsule will generally have a lower SNR as there¡¯s more signal due to the larger area and the noise is mainly generated by the electronics. But yes, if you add several smaller capsules with

Re: capsule array self-noise
Thanks, Marcel. Are you saying a 5-cluster's S:N will be 2.25 x higher than a single one? Or under my scenario a same-area large capsule? Let's simplify the scenario: two small capsules vs. one larger
By John Thaden · #35828 ·
Re: capsule array self-noise
If all the 5 capsules have the same weighting in the array, S/N would increase by 2.25 (about 7dB). However, proper arrays have different weighting and phasing for each mic. Typically, arrays are used

Got it, thanks Jules!? I'm actually familiar with that concept from another field (mass spectrometry). So now this followup: If a cluster of 5 small capsules around a center one has the same total
