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

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

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

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
