Pro Tip: Don't cut off the Bulk connector (2:14) leaving this pin floating will definitely worsen sound quality. Instead, connect it to the ground of the circuit. Otherwise the microphone performed is heavily influenced by EMV and room conditions

[@SpartanJoe193]

I can tell that has something to do with the harshness of the mic.

[@birb3635]

you can notice in the comparison at the end that yeah there is a slight little bit of room noise in the microphone along with a little harshness. Very good advice!

[@camoman619]

If you want to get really fancy about minimizing noise you’d also keep the digital conversion away from analog preamp circuit (not hot glued right next to it) and shielded. Also the grounds & shields should avoid forming loops and instead be tree shaped (going back to a central point of grounding ie the Audio ground)

[@ArrAnheAton]

Just prefacing this with the fact I'm a professional audio engineer, with a Masters degree in microphone preamp design. For the price and required skills, this is AMAZING! such a cool build idea! I'm currently out on tour so don't have access to my workshop, but will be attempting to replicate this as soon as I get back home, with a few minor tweaks. 1) really simple, you even touched on it in the video. The rear porting for that capsule is compromised by the brass casing. Instead of using a brass ring with holes drilled into it I would suggest soldering the two brass grills together directly. A little bit of thought will have to go into shock-mount mounting rings but it will be worth it. You're effectively making the Mic HyperCardiod in its current format. 2) this will sound really stupid, but placing a stretched piece of thin breathable fabric such as a pair of low denin tights (stocking for my American readers) will really really help. As it stands the microphone is slightly more simple and than I would like it to be and I found myself noticing S's and the odd plosive here and there. the next two are completely optional but could be really cool additions to the project and help the sound quality. 3) whilst I can see you are using basic filtering in the preamp stage I would suggest adding an R/C C/R EQ filter to roll off everything below 30 Hz and everything above 18 kHz as the capsule will struggle to reproduce anything outside of this frequency range however the preamp will still be wasting energy amplifying noise you can't hear. These are a few of the additional components found on a lot of pro microphone circuit boards. a really simple step, massive quality difference. 4) sorry the audiophile in me had to... Try and use film capacitors where you can. Basically anything other than electrolytic as they start to introduce undesirable noise into the signal chain. On something like this, it wouldn't be the end of the world but when you get a few going into each other the effect really starts to add up. 5) I'd love to see this with the Texas Instruments INA217 mic preamp integrated circuit. It's quite possibly the best budget preamp circuit you can find, period. 6) I love your idea about using a simple premade USB to audio adapter, why don't you integrate the headphone output as well with simple passive volume control this would turn the unit into an amazing audio interface. I'll drop you an email with these comments and a few other really nerdy ones as well for you to use or ignore at your own call haha. But overall, I can't say how cooll this project really is! I'm going to try it out with the weeks mentioned above and see if it's worth it. Would you be interested in doing a comparison video? I have a couple of Neaumanns & AKGs in my touring kit and would love to do an A/B. All the best, Arran. P.S. If anyone else wants a list of the nerdy stuff just drop me an email: [e-mail]

[@TibiHell]

I watched this video with ok earphones but I could ear a slight noise on the DIY mic that wasn't present in the Neumann, so if you compare the cost/quality ratio, the DIY mic wins by a substantial margin, but in terms of raw quality, Neumann stays king

If he made another identical mic there's no way it would characteristically sound the same.

[@platinumsky845]

@@_BangDroid_ unless you're able to create two and demonstrate that there's drastic differences between the two then is just speculation, regardless of manufacturing method there's always going to be some measure of error, however with The complete isolation of the capsule It's entirely possible that the majority of differences between multiple manufacturing runs would be insignificant enough to be near unnoticeable aside from simultaneous side by side testing. Until you can demonstrate this difference is drastic enough to become a problem then it's just speculation. Very important speculation that should definitely be considered, but still just speculation.

As a sound tech, I'd like to make one correction: the way that professional audio cables protect against electrical noise is not from the shield. That cable with the shield that was shown is for something else entirely, but it does often get used as an audio cable, because it works just as well. The way that professional audio cables actually protect against electrical noise in the cable is through basically sending 2 copies of the audio signal at the same time so the destination device can remove what noise it can. This is called a balanced cable. Audio University has a great video on the subject of Balanced/Unbalanced cables if you want to know more. However electrical interference shields are mostly used in digital signals such as those that get sent through USB, so without doing extensive testing on this build, the shields used aren't necessarily pointless or bad to have.

Professional Audio Guy here: The comparison from 21:57 pretty much knocked me out of the ballpark. Obviously the U87 sounds better. It has a bit more natural compression in the highs and it doesn't sound so harsh with the s-consonants. Also the resolution in the mids is much more articulated - this is very important for the character of a voice. With the DIY-Mic you have a bit less natural compression and a bump in the highs, which you would have to process in post. BUT! The resolution of the DIY is superb. I tried to make out a noise floor, which is impossible with the youtube compression and that is a very good sign. It also has a very smooth and buttery low-end which would make it perfect for other use cases. Investing a bit more time and much less money and making this Mic? Definitely worth it!!! Great Video through and through!

[@madoba8717]

As a Professional Normal Guy here: I beg to differ. The U87 has much more mid to low range and makes his voice sound quite muddy for my taste. Now the $3000 microphone may pick up more and “cleaner” information which may be eq’ed/edited or whatsoever in post, but the space and higher end frequencies that the DIY mic picks up sound really good, and are much easier for me as a listener to enjoy.

So, I would say the unprocessed audio from the U87 definitely sounds better, but once they're both processed you could make them sound damn near identical. The DIY mic had pretty much the same level of low end as the U87 but had a lot more presence in the high end, which honestly unprocessed sounds a bit harsh, however it has more sonic information that you can play with in post. With the U87 you'd probably throw a boost on the high end to give it more of the air that the DIY mic already has, and with the DIY I would do some cutting in the high end to make it less shrill. In the end they'd sound pretty much identical though, which is incredibly impressive.

At least listening through my cheap phone dac and bassy PortaPros, I totally agree with you. The Neumann sounds like it's massaging my eardrums and like it had an integrated de-esser or something. No annoying frequencies at all. It's a beauty. The DIY has a really good sound, quite bright and with a nice low end as well, though it desperately needs a compressor and a couple of filters but it still sounds really good, especially considering that it's self-contained, cheap and with a DIY preamp.

[@supermaster2012]

to me the only difference is that the diy mic is more raw sounding, I think adding a very thinn tensed cloth in front of the brass mesh could go a long way softening that rawness.

Before I say anything else, I just want to say that I respect Matt and this video so much more than many youtube project videos. My mans actually did a ton of documentation for this and made it really easy to recreate. This is probably one of the best diy mics I have ever seen in terms of quality and feasibility to build. So, I built it. And yeah, totally sounds like he said. I’ll gas it up as much as he says, it’s really nice. I have been thinking about this project for three straight weeks now and I really do feel like the payoff was worth it. 90% of this project was waiting on parts and existing in a sunken cost fallacy purgatory, but overall, if you plan on doing this, most of the parts here take a good amount of time to get here (especially if you order from china, which is necessary for price efficiency). And that’s all I can really say about this. It’s a good mic, I rate what Matt is doing and the amount of time and research he put in. But there’s one big thing that bothered me about this project. The cost for all of these components is not ~$30. Not a chance. As you can see in my spreadsheet below, not 30, not even 100 dollars (accounting for possible currency conversions). If you don’t have a ton of brass, wood, and the proper capacitors lying around, you will be spending more. That as well as the fact that some components are just not available in the states. I traded the THAT1512 for a INA217 because of this. The INA217 has different resistances for gain but other then that it is largely the same (not really, I would still like a THAT1512 but they take 4 months to get here it seems). The finish of brass and wood is cool, but completely impossible for people that don’t have tools to work with them (also there’s no specs listed so I’m not sure how you would do that anyway), so I 3d printed everything (box and module holder) so I didn’t have to buy anything else. The cost I listed accounts for these even more budget considerations, so all in all I would call this a budget mic, but with a hard asterisk. I want to stress again, this project is so cool and I’m really happy I did it. Just do your own budgeting before hand and make sure you can sweat $150+. I included some pictures of my build and all the stls (as well as a fader knob I stole from thingiverse I cannot find the original link I will update if I find it)) Definitely worth the time put in. Here are some resources from my build: drive.google.com/drive/folders/1Ax8V7ID-nKL7wJXj9A7RIaR2wb1TqigN?usp=sharing Direct Link to my spreadsheet: docs.google.com/spreadsheets/d/1pQlkRerO5geoDNLEWXTUVbyJalM7nESn/edit?usp=sharing&ouid=114689008105602245905&rtpof=true&sd=true Edit: Here's a quick write-up I did on this with some sort of instructions-not-really that might be helpful: github.com/TrojanPinata/DIY-Mic Edit: As of writing this, t's been a little over a month now since I made this mic, and honestly it still holds up. I finally have a THAT1512 coming so I think that will fix some of my gain issues. Overall, I definitely still like this mic. I use it pretty regularly and get compliments on the quality. If I used it more then I do currently I'd suck it up and buy something really nice, but this will do for now. As for this project, I still really respect the original build. For those complaining about me saying I with there were more verbose instructions, I think you're missing my point. I just kind of with I had a better idea of some of the specifics. That being said, I'm probably never going to do this again, what with the posting my version of a project online. Some of you all are great, but the number of armchair engineers here is wild and I really would rather make things because I like them and not have to deal with people nit picking a writeup I did one morning before work. I mean, I don't know what I expected from the youtube comment section. Anyway, I'm done, enjoy your mic if you're building it, and if you aren't then I really don't care what you have to say about the way I did things. Later.

Thanks for sharing!

[@toothlessblue]

Also in the process of making it, and yeah, totally agree - I'd like to add that as a video this is a great, easy to watch and share bit of content. But as a tutorial? The circuit diagram and the circuit in the video doesn't match - some capacitors appear to have changed direction?, the parts list only consists of what he had to buy not what he used - and there are measurements missing like the length of the brass rods, the difficulty and process of each step didn't come off well - maybe I'm just supposed to know how to solder brass but he made it look easy so I didn't bother looking anything up and screwed it up a couple times, he skipped over the wiring for the analogue to digital converter, and to top it off there's an advert smack in the middle of it. I'm being really picky but having to follow the video has made these bits stand out

[@LunaWitcher]

Honestly I would love to see people remaking this with whatever they have at their disposal. You have a 3D Printer, he has apparently access to a ton of brass and some wood, someone else might only have access to wood or plastic...

[@jmiddlefinger]

Could’ve been really cool to add some kind of “pop stopper” using that same brass mesh further in front of the capsule to minimize the blow of air across the capsule during plosive sounds. I’d also recommend running a de-esser in your audio program to minimalist sibilance from your “s” sounds.

Thoose caps are just too big for the mic transients, probably with 470uF on both sides and 2 in parallel on the USB in would be better. I would have put some smaller ceramic cap parallel to the main bulk ones to filter out the DC DC converter noise. For the decoupling caps i would have choosen a polyester type one. But this is just a preference. (I try to avoid as much as possible electrolitics ones)

[@cynicaloutlook]

@@pigpiggig I'm not aware of the reason for avoiding them in audo gear, but the reason cheap capicators had a habit of failing in the past is due to industrial espianage gone wrong - a researcher from Japan defected to China with a design for long-life caps, who was paranoid about his lab assistants defecting in turn. To prevent this, he gave the assistants misleading designs, who then passed the designs on to Tiawan, who in turn gave it to their businesses to mass produce - end result was a flood of capacitors on the market that were designed to fail after a short period of time; this is also why there was a period when "Japanese capacitors" were considered better quality.

[@tuttocrafting]

@@pigpiggig each capacitor kind have different characteristics. Electrolytic one are less precise than other types. They depends a lot by temperature and they al bulky. On signal paths it not necessarily at all to use hi grade electrolitic capacitors. Probably over there also a good ceramic one might have been enough. Generally electrolitic caps degrades more than others over time, especially if they are cheap. Anyway there is a great article on Altium websites that explain a bit the difference between capacitors types.

As a retired sound engineer i admire Matt's skills.

[@richcodesweb]

Philippe, I'm sure if you use the same designs and just changed the capsule, a more "Neumann" sound could be achieved, yes the price would increase, but how much would depend on the capsule purchased. If you had a Neumann though that was otherwise broken somehow but the capsule was intact and functional, it would be the perfect recycling project for that microphone ...

[@mylittlehomeinparis]

@@richcodesweb This is certainly exact but purely hypothetical Neumann has worked on condenser capsules since 1928 and there are few if any prepolarized capsules that could beat this sound quality Although everything depends on what you need the microphone for. When you record a sound there are usually a number of post processing steps coming after and the better the quality at the beginning, the better it will sound on the finished product No wonder it is a standard in the industry (along with one or two other brands) (pardon my bad english !!)

Its a good circuit, but i have some suggestions: - put a ~220nf ceramic capacitor RIGHT across the leads of the ic. - component selection is important for the ac-pass capacitors. Non-polar electrolytic is fine. Tantalum is very bad. Ceramics can also work, but bear in mind ceramics may have a microphonic effect as well. - place everything that connects between the ic and the microphones as close as possible to each other, and make sure the connection between the mic cable ground and the amplifier ground is as short as possible.

[@HoobtheNoob]

Audio engineer here - I record voiceovers daily with the original U87 (it's a little nicer than the AI) the real noticable difference between the two mics is that the custom mic has more harshness in the high end - it's a little more brittle sounding which once you apply compression and post production processing with result in more sibalance (loud s's). The U87 is also a little richer in nice low frequencies. but given that is a 30-40$ mic it's ludicrously good quallity and you could easily use it for proffessional purposes especially as a content creator as you don't need to process your voice as much for longer form videos. If you made this I wager you wouldn't be looking to replace it for quite a while. Looking at the alernatives in this price range people often jump to the blue yeti as an easy choice but I can say catagorically the blue yeti sounds absolutely awful compared to this wonderful build.

[@KrisMitchellnet]

I actually found the high end in the DIY mic quite unpleasant, especially after listening to the U87; the U87 needed next to nothing for de-essing or EQ. As another commenter pointed out, there's little-to-no chance in getting these parts for $30. I'd assume $100+, depending on how serious you are with the fit-and-finish.

@@philmissy1 theres a reason people pay thousands of pounds for microphones and still eq them afterwards even if it’s the best recording in the world. The room affects the sound, every persons voice resonates differently and has different tonal characteristics, the genre of what you are mixing - both music and audio visual content. Using compression to make the voice more audible at lower levels. The list of reasons you might post process a voice goes on and on.

yep my thoughts exactly. But, would anyone not in the industry hear it? After post of course people would notice. but un mixed? not throwing away the 7B's and 87s yet. but this was for sure eye opening. especially with the company he bought his capsule from. They sell a lot of different ones. Ive been going back and forth on them for awhile.

Speaking as a sound engineer, the quality of your mic is definitely surprisingly good! There are a few issues it certainly suffers from, but overall you've done very well. It certainly seems very useful in a voice over or streaming set up, and certainly exceptional for a usb mic. I was surprised by the frequency response, it is genuinely very clear. The high mids (from what I can tell purely based on the audio from your video) seem to occasionally be a little harsh, and the low mids can get slightly muddy, but that might be an issue with youtube, or worse, me nitpicking. I think it has a great amount of low end of a vocal mic, enough to clearly pic up the full bottom end of voices without overdoing it. It feels almost unfair to put it up against the u87, it's a truly gorgeous vocal mic, even to untrained ears. the u87's only real downside is that price tag, but then again, that's basically everything in the sound industry! I think this was a really cool project and an awesome result! and it's just made even more impressive by the low price tag. Love the look as well!

[@glenesis]

Agreed on all points. It's pretty gorgeous. I think it sounds great, considering there's no EQ circuit. I'm very impressed. I could work with this signal. Cheers, Lydia! Pleased to meet you!

I love how the design of this mic looks like something out of the experimental stages of the mic back in the late 1800’s or even in the early stages of analog radio! Lovely build and great sound quality considering it’s only like 50 CAD to build!

[@Skyflairl2p]

As an audiophile with quite expensive equipment and a musician with 12 years of experience I consider myself an enthusiast to say the least. And honestly, wow! I own 3 microphones spanning from 200 to 1.5k USD each with unique sound signatures (no flex, context) and if anything would LOVE to try on this DIY setup. Between the Neumann and the DIY though there is definitely a nuanced difference in frequency response, but for podcasting and home studio's its nowhere near worth the price (not even close!) and the difference is really so slight that it would only be worth the cost for really professional work. Plus the DIY setup allows for INCREDIBLY CHEAP maintenance!! (Just the repairs of a Neumann would cost 10 times the price of this build lol!) So really, Matt - incredible job with this. I definitely see it as a no-compromise build for an incredible price.

There is another aspect of your DIY mic to take into consideration... Aesthetics. Yes, the Neumann mic is technically slightly better in sound quality, but your mic completely crushes it from an aesthetic perspective. It looks amazing.. stylish.. unique.. literally a piece of art in itself. Incredibly well done!

[@tiagotiagot]

With a full matte black finish, it would be quite discreet even if placed almost exactly between someone's face and the camera, that thin minimalist structure with the floating capsule, barely causes any occlusion; something like this design might get popular with streamers and such, I think.

Amazing job with this build and I'm sure there's even more room for improvement. Your build sounded so much better that the $3000 microphone! Your craftsmanship with brass was a nice touch in the polished and retro mechanical and wood look and finish. Audiophile quality in every way! Bravo!

[@AbdoZaInsert]

@@sebastian-benedictflore I am not joking, but for me its much better.

[@sebastian-benedictflore]

@@AbdoZaInsert There is a level of objectivity to this. That's why people have jobs in the field. If you wanted to record professionally, that microphone is not on the same level as the Neumann. You can have your personal opinion about what you'd rather use or hear for a voice over like in the video but there are many things that make the Neumann considerably better. I am no audio engineer so I couldn't go into all the details and intricacies and we also only heard a particular sound - the same person's voice and nothing else. However, even I can tell you that the levels (in terms of EQ and pickup) aren't quite right. Compared to the Neumann, the clipping on the home made was quite bad, for example. In a professional environment, I'd expect some would call that audio almost unusable.

[@ecoista1373]

@@sebastian-benedictflore What makes you think this is not a professional environment? Dude is literally manking content - high quality content. Like with most things, you get a pretty steep diminishing returns for more than 100x the price.

[@sebastian-benedictflore]

@@ecoista1373 yes, you get diminishing returns but that does not mean that this is at the same level of audio quality as the Neumann. What on earth are you talking about (referring to the "professional environment" point). Whether or not that is a professional environment doesn't even matter since he uses a better microphone anyway. No, that microphone is not adequate for a professional environment and when I say that, I'm not referring to any job. I'm referring to music production, a high profile/quality radio station or other such situations. That microphone is not versatile enough and there is quite a bit of clipping and I'm sure that a professional audio engineer, unlike myself, could find more problems. It simply doesn't have the quality and versatility that some applications demand. It's ridiculous to say that it is as good as the Neumann here. As for the quality:cost ratio, that is an entirely different matter.

The Neumann definitely sounds better imo, but if I'm not listening to them side-by-side, I might have a harder time telling a difference, which says a lot given the price differential. I know that if somebody gifted me the diy mic, I'd love the heck out of it. I have a few friends who would benefit from a higher quality mic, so maybe this could be a fun project for making Christmas gifts (I know there are people who feel that homemade gifts are more meaningful, and this definitely beats knitted socks.).

[@elibeeblebrox1084]

This is where a better audio system would help your ears - or hurt them, depending on your perspective. I won't go into detail on mine, but the DIY mic is closer to 90% the quality at 1% the price. Still an unbelievably massive win. The expensive one is warmer and the DIY one has some high frequency hiss - which could be eliminated with a low-pass filter in a future circutboard design(which would mean an extra resistor and tiny capacitor on the board) - or maybe even a ferrule on the cable. Hard to know where the hiss comes from without personally diagnosing it. This is of course totally pointless unless you're a content creator aside from the fun of pushing things to perfection. There won't be a noticeable difference in the bitrate of a discord call.

[@zypity]

The Neumann sounds a bit 'fuller' in the deeper frequencies, though not 100x the price deeper. Myself not having any of the required materials or workshop equipment at home, this thing would probably cost me an initial $800 to build (though I could keep the equipment as well obviously)

[@themanofmarvels6573]

Why does it even matter on KZbin lol. This diy mic is the best choice as it's cheap and Sounds good. And youtube compresses any audio to the same bitrate, we can't find a difference unless we hear of both is them simultaneously

[@zypity]

@@themanofmarvels6573 None of us really stated it mattered, that's just you reading into it. You are correct that youtube compresses audio and makes for a bit of a hard comparison, though hearing a difference is definitely a valid statement.

The expensive mic has a fuller sound, its like what you'd hear audio books being recorded on, but the DIY mic sounds more like real life imo, its a more natural sound

[@user93237]

This makes me wonder whether the "fuller sound" can simply be achieved by post-processing using an equalizer to lift the lower frequencies a bit. I've followed a podcaster who has simply done that in order to make his voice sound more "soothing" and "professional".

[@eleftherios11]

I believe that no post processing is applied on that mic. Audio books are processed

[@jamesyahoo4758]

No matter what, the sound is gonna be compressed by some lossy codec, sent buzzing over thousands of miles of cables, both fiberoptic and copper, then sampled once again by the telecom equipment, beamed from a tower, and picked up by your phone, decoded, sent to a DAC, and finally played over the more than likely crap to mid-crap speaker in your phone. So, does it matter which microphone he uses? Not a goddamn bit.

[@jacobpugpoirier3350]

Buy natural you mean, even the minimalistic amount of saliva in his mouth?

[@Madrrrrrrrrrrr]

Fuller means more compact. No weird highs and lows like the diy mic but a much more balanced mid sections that stands out more and cuts better through the mix. That's why you don't see podcasters with a 87. It's a singing mic for music production. Also a Scarlet is sub par for a 3k mic as preamps goes. A lot of mics have a kind of paper/fabric behind the mash to soften the sound a bit.
