4 Ways to Build a DIY Jecklin Disk (and why you need one)

[@alphanumeric1529]

For proper A/B'ing, you should switch immediately between sources, all the best mix and mastering engineers do this when evaluating subtle moves. We have terrible sound memory for the tiny differences between sounds, so listening to one, then 30 seconds later, listening to another is far from the best way to analyze two similar sounds. With these time links, you can quickly jump to different sounds, like strumming with no disk right to strumming with cardboard disk. I think you'll be surprised in what you hear. I prefer no disk at all - larger image, and it sounds more "natural" meaning it doesn't sound like the sound was "messed with" which is a sense I get with any of the disks. I don't have the aural sophistication to pick out exactly what the messed with sound is, but I've learned to trust my ears. When something sounds unnatural, I don't use it. 4:47 Strumming, no disk. 5:45 Strumming, disk w/ foam. 6:24 Strumming, disk w/ cork. 7:04 Strumming, disk w/ felt. 7:44 Strumming, disk w/ cardboard. 5:04 Picking, no disk. 5:59 Picking, disk w/ foam. 6:39 Picking, disk w/ cork. 7:19 Picking, disk w/ felt. 8:00 Picking, disk w/ cardboard.

Just like any stereo micing technique, it only works when you hard pan 100% L & R. Also, IMO I believe if you mounted the desktop mic mounts all the way back to the edge of the disc so that the mics are centered more on the disk, similar to how the human ears are centred on the head. That, along with fanning the mics out similar to the angle of canting on the human ears. This is by far the best way to do any stereo micing! Thanks for the vid!

Jose R Thanks, Jose. Yes, it's hard to tell in this video but the microphone tips are actually dead center in the disk (the camera angle makes them look far forward) so make sure you mount however you need to in order to get that placement.

[@TechnoJon96]

Great video. Loved the corkboard, sounded very natural to my ears. & an aesthetic to die for

[@everope]

The felt one had the most coherent center image to my ears, which is the most important function of the disk IMO. I would have liked to hear them panned 100% left and right too. I would put a single speaker playing pink noise in the middle and then use a correlation analyzer to see which does the best

Have you also tried to build a schneider disk? So basically a jecklin disk with a halfball on everyside to represent a head roughly

[@centonuovimattini]

what's the difference between a jeckline disk and a Schneider disk?

@@centonuovimattini haun builds a schneider disk ... imagine not having just a plate with acoustic foam but a ball out of foam that represents something like a head ...

[@dag451]

Thanks for this Jordan, it's been very useful.

[@SosstudioCo]

Glad you liked it, Dale! Let us know how your project turns out and if you uncover any new tips or tricks.

[@CraigCoggle]

Thanks for this video... it's a new concept for me. I liked the foam results and will probably mess around with some acoustic foam as suggested by Jeff.

[@Flitzefeuersocke]

I liked the corkboard best, sounded the cleanest to me compared to the cardboard that has more reverb to it. But I don't see why you would use the JDisk in a studio with a single player. You could also mic the guitar with two mics and pan it. Probably more useful for a group where you would want the stereo effect.

[@BishopEddie5443]

Never heard of these but I can see why they make a difference. You might try denting the cardboard or adding some cloth strings in different patterns for texture.

[@Blacktopcowboy]

I’d say a mix of cork and felt would be the ideal setup. Foam sucked too much highs and dynamics. Cardboard wasn’t bad surprisingly.

[@DOUMSTREAM]

I think you should have put the mic's mounts more at rear because the capsules are too much in front, close to the end of the disc... But interesting vidéo

[@KanarisLkanaris]

Well done my man

[@rafhaelbarajas4879]

I love your work, congrats!!!

[@michaelbennett9127]

I reckon sound treatment foam would do the trick; maybe two if you're in the mood. Although, I'm in the camp that believes DIY is don't involve yourself, especially if it becomes a headache

[@kevinreddoch5214]

So when I was taking recording classes in college we took a mannequin head and put mics on its ears. It got pretty good results.

[@horsenamedbird6249]

LMAO

[@sinoffl]

If you do not want to disable a mic boom, get a OnStage Posi-Lok clutch and use half of it.

[@lauriemarvel]

Thanks, good ideas!

[@everope]

I liked felt the best

[@ytubeanon]

Foam sounded best, it had a 'bright' quality that the cardboard deadened.

[@lumpyfishgravy]

Liked None and Foam. Didn't like Felt. That was with monitors. Gonna try cans now. I was right, cans are quite different. Not a good sign. I think your disc is too different from the original plans.

[@piccman1]

Try Acoustic Foam next time. Much more dense. will get better results than cardboard. FYI the disc is pronounced "yeklin"

[@SosstudioCo]

Jeff Markwick Hey Jeff, thanks for the insight on pronunciation. I forgot to take into consideration that Jecklin was Swiss! I'll certainly try the acoustic foam next. In my analysis, the corrugated foam provided a nice diffusion dynamic compared to the other materials I tried, but the thickest foam I had was 3mm. I know a true sound foam would throw in a whole new perspective. Thanks!

[@ericroberts9259]

@@SosstudioCo I believe you mean corrugated cardboard, not corrugated foam. Thanks for the video.

[@europeanambience]

Can't hear any difference with or without 😅

[@GryptpypeThynne]

FYI, Jecklin suggests that the mics be spaced 36cm apart, which is considerably more than what it looks like you have here!

[@jackmontreal1]

I think its 165mm. and the disk should be 300mm.

[@CaseyConnor]

@@jackmontreal1 Apparently Jecklin's original was 165/300, but he eventually arrived at a 36cm separation between the mics and a 350mm disc. See e.g. the wikipedia page on Jecklin disc. I've read others online having a similar experience: wider mics seemed to work better.

[@garyabbot4659]

Can I use two different mics?

[@LearnAudioEngineering]

You could, however this wouldn't be true stereo micing. It would be more of the multi-mono thing. The exception being Mid/Side which uses a Cardioid and a Figure-of-8.

[@dothenextscarything]

Whoops! Your intro song is in mono! ; ) Cool video though!
