Skyline Diffuser build and A/B test

[@therockhour1386]

Even on my phone speaker... you can hear the diffusor dramatically improves the clarity of the sample material

[@NikulPrasad]

Thanks man, the A/B is what I needed. I am definitely going to build one now!!!

[@odindejong6801]

good to hear! goodluck, post a pic when your done

[@xaiano794]

2:15 that sounds like a big difference

[@antiHUMANDesigns]

Very notable difference, yes. Note that because the diffuser isn't very "deep", it will only work on frequency above perhaps 500 or 700hz, or so. It will do almost nothing to lower/bass frequencies unless the diffuser is much deeper. It also won't do much above about 5'000hz because the size of each "well" is too large. For example, if you want effective diffusing down to 200hz, you need almost a meter deep diffuser. And to get diffusing up to above 10'000hz, you need each well to be perhaps 1 inch, or 2.5 cm, or smaller.

[@Amish6Stringer]

The before and after is dramatic, but would be even more dramatic if you didnt just lay the diffuser down on your bed, but remove it from the room entirely.

[@mustafakhettymusic]

What is the approx weight of 24 in x 24 in single diffusor?

[@SpirosAbatis]

Great video! Nice to see an A/B test done properly! Thank you.

[@KalleHullu]

How much does the diffuser improve your mixing?

[@thanoslefthand806]

savage bro

[@rickspyder1]

wow now u know wtf to do thanks for the info...project studios can do so much to improve before spending fortunes on hear.

[@Engineering_Science]

Skyline Diffuser does seem to provide better acoustics.

[@peterheinen6110]

Great results!! Better than just using absorption (which is useful mainly for standing bass waves). I have the natural advantage of an a-symmetrical attic roof. Don't forget to put speakers in the smaller side of a rectangular room.

[@odindejong6801]

Peter Heinen thanks peter!

[@Rizafoolwitit]

crazy sound difference. great video!

[@marocatworkrecruitment5073]

What is the frequency for a callcenter?

[@quanglangthang789]

frequency of voice people is 1000 HZ~4.1kHZ, so we only treat in this frequency zone. Diffuser calculator based on decrease RT60 of 1000HZ in 0.3s~0.5s is perfect

[@BlakeKross]

nguyen quang I think you’re mistaken. The fundamental frequencies of the human vocal range is typically ranging from 100-700 htz, however a lot of professional female vocalist can reach past 1khz threshold...not 4kHZ though. These fundamental waves are the waves needing the most treatment in a room with reflective walls. Harmonic frequencies in voice stem above/ below these ranges though, so that’s where diffusion like this is effective. Along with most instruments. Diffusion in this freq range is still effective but not as effective as absorption for immediate treatment at lower frequencies for vocals. (IMHO)

[@LDBaha]

How heavy is this?

[@odindejong6801]

Daniel Bencomo don't ask..

[@ClashixTV]

omg!!! the differences were HUGE! i gotta build one!

[@stewartimel]

Cool video, thanks!

[@joernbeckesch5980]

Hi! Heel goede vid, Odin! Bedankt voor de vergelijking. Groetjes van Jörn

[@Aofex]

The A/B comparison was a really nice addition. I didn't think you could hear the difference unless you were in the room.

[@odindejong6801]

Hi aofex, you tried some good headphones yet? you would hear it for sure. greets

[@Aofex]

Odin de Jong Oh, I hear it well, it's just that I thought that you had to be in the room, I didn't know you could hear the difference in a recording.

[@KingCoCo]

interested to know how you decided to go with the 1k-4k range?

[@odindejong6801]

Dirty Needlez well thats mostly because the dimensions of the diffuser itself. If you want to have a diffuser that works at Lower frequenties, then you would need a lot deeper diffuser.

[@KingCoCo]

Ahh ok. Did you do any frequency tests beforehand with Room EQ or anything like that? I'm working on my room at the moment and studying up so I can get the best result first time :-)

[@s4salenow]

nice work man! And great before/after demo too! This really shows how important diffusion is in a room! However, each diffuser is meant to work at a minimum listening distance so, when you move the mic close to it, you don't really get the REAL results.

[@sebulbathx]

My thought too. The difference with the mic close was marginal. However with the mic further away the difference was dramatic.

[@алексейпетров-ф2р]

can he remove the reverberation of the room?

[@odindejong6801]

hi, no a diffuser is not meant to lessen reverberation, that where absorbers come in handy. what it does is it scatters the sound waves so you get a more even and bigger sounding room.

[@rik-keymusic160]

Hello, i want to make a diffuser myself but i'm a bit confused about the frequentie target... i have quit a big room to record acoustic piano music but i don't know in which range of frequenties i should target at? in other word, how do you know which frequenties suites your needs? ... thanks for the video!

[@odindejong6801]

Don't worry to much about that my friend, it is just that how deeper you make the diffuser the more low end it will be able to diffuse. But that doesn't come close to any room modes, so tuning a diffuser to your room is not needed at all. Just go with the specs in the video or similar and you'll be golden. Goodluck

[@rik-keymusic160]

okey, thanks :)

[@mikefire2740]

Thanks!

[@sebahattin1906]

Thank you for this video.i will make a diy one myself.i have about 500 pieces of wood that about 5cm x different sizes.i can make a big diffusor like yours or 5 small diffusor s for around the room.which way that i must prefer?

[@JM-co6rf]

Watch at 2x speed

[@JesemanuelRamirez]

thanks for the video, most videos dont show comparisons for some reason and it drives me nuts. Thanks for sharing

[@odindejong6801]

bedankt ben! ik heb wat ronde haken gepakt en die zo verbogen zodat de bovenkant vlak is en ik zodoende het paneel nog naar links of rechts verschuiven om te corrigeren. en uiteraard hoger of lager door het schroefdraad van de haak. verder gewoon dikke pluggen en schroeven in de muur

[@badmacbassandbass8118]

Why did you only paint some blocks and not most?

[@bentyreman5769]

looks and sounds great, out of interest how did you mount them to your wall? I have just built one and it's weights 18KG! very very heavy

[@ObscenePlanet]

search "french cleat". there is a DIY on using metal room dividers (for carpet)

[@ClashixTV]

lol 18kg is nothing and i dont even work out xD

[@quanglangthang789]

i want to ask you: what does square size of wood decide? and what does the lenght of wood decide?... it is so important

[@jokindajoker]

Amazing difference when mic is on that mix position

[@pandasuper6972]

Funciona más en las frecuencias medias

[@thijs199]

The close mic is not effective.

[@damienpercy5245]

I couldnt hear any dfiiference

[@estebanescobar180]

Why they changing pitch tho

[@guguigugu]

seems to work best for midrange

[@greggiorgio1846]

The A/B was very helpful! Thanks

[@rb032682]

nice build. Great demo too.

[@11219tt]

First off in amazed at how the sound changed. And I'm listening from my iPhone speakers. Question: why did u choose 1k-4K frequency?

[@odindejong6801]

1k-4k are just the frequenties wich it is most effective on given it's dimensions. if you wanted it to be effective on lower frequenties, you would need a VERY large diffuser. just not practical. cheers

[@bbfoto7248]

+Odin de Jong Nice work! I wish that you had uploaded this video in a higher resolution to achieve better sound quality via less compression from KZbin's lossy audio codec. You must use at least 720P quality to achieve better audio quality via KZbin. Is it possible to provide a Link to download these samples in at least 16 bit/44.1kHz lossless WAV? Or to reupload the video at a higher resolution? Combine your back wall diffusor with 4"+ thick mineral wool/Roxul absorbtion panels around its perimeter to achieve a much greater effect. And it seems like your microphone was placed a bit too high in front of the diffusor for these measurements? If you don't have a glass viewing window between your control room and a live room, this same technique works great when placed between and behind your studio monitors....and of course in the corners as well. However, IME the most important reflections to "kill" are the 1st & 2nd reflections off of the side walls...using the "mirror on the wall" placement technique. A hanging or suspended "cloud" diffusor/absorber that extends forward and backward over the listening position also produced incredibly good results in my listening room. I didn't realize how much bounce I was getting off of the ceiling! Still, I really appreciate you taking the time to post your audio "before & after" results. It would be really cool if you used a Neumann Binaural Dummy Head microphone at your listening position. :-) But that's $$$!

[@odindejong6801]

bb foto you got it all figured out! Thanks for the comments. I made this video when I was a lot younger and really didn't knew much about what i was doing haha. With the knowledge of today i really should make a new video, also with all of my other video's. My studio is miles away from what it was in this studio haha

[@bbfoto7248]

+11219tt Well, your iPhone speaker is most sensitive to the frequency range that this type of diffusor affects. ;-)

[@officialWWM]

It didn't fix the terrible theme music!

[@odindejong6801]

Music Islife sadly I must agree with you 😂 hard to find copyright free music

[@officialWWM]

Odin de Jong you have a studio....record some, lol.

[@juergenengelmann4629]

incredible, you can hear it really good

[@odindejong6801]

thanks!

How did you hang on the wall?

[@odindejong6801]

İlkay Dinsever Google "french cleat"

[@assi4grass]

i have a question please should i know the Frequency in my Room to make this diffuser ?? how can i know the frequency in my room ? i mean the Low and high thanks

[@SoilRec]

Hi. I'm not secure about this. But my logic tell me that the frequency is the "Frequency response" that the difussor have above the sound. If you see a 30 band eq, you can see the frequency in each band. So these difussor acts on the 1k to 4k Hz frequencys.

[@odindejong6801]

hi, i think what you refer the is ''Room mode'' you can calculate your room modes very easy by measuring the distant from wall to wall. then put the outcome in a didstance to frequentie calculator (you can find those online). Keep in mind that a diffuser won't solf those low end frequenties, only basstraps, speaker placement and speaker calibration will do so. Good luck

[@SoilRec]

The room mode is for low frequencys?

[@odindejong6801]

SoilRec all object have a resonating frequency, depends on the size and dense of the material. a room has dimensions that corresponds with low frequencies because rooms are pretty big. the resonating frequency of a room can be anything from 20 to 500hz or so. when you know your room modes, you know what frequenties Will be louder in your room

[@SoilRec]

i'm sorry for too many questions but i have one more haha. Now i know my room modes with the calculator, it show me just low frequencys (like 40 hz to low). That says me that i need some bass traps? Question 2: How you decide how many difussers put in the room and how you decide the frequency range in this? thanks a lot.

[@HavacFilms]

Wow

[@trentoproduccento]

good job

[@EtreGenerique]

Sorry but it's not better.

[@odindejong6801]

Zen Legiendly did you listen on headphones?

[@aa.music.production]

You be must be deaf

[@eduardcornelis8162]

netjes gedaan !

[@odindejong6801]

Egon Constancia thank you sir

[@odindejong6801]

Egon Constancia thank you sir

[@zagarelos]

I can hear the defference but the sounds are exactly the same in the comparison.. before and after.

[@Jaburu]

thanks for this. close mic actualy get's bad. confirms that you can't use them close to listening position. at mixing position you got rid of that very bad flatter echo, but on the downside it is noticeble colouring the sound

[@MrObelisk2290]

painting or shellacking makes them reflective and in a BAD WAY

[@odindejong6801]

+Jose M A diffuser should reflect, explain to me why it is bad?

[@MrObelisk2290]

+Odin de Jong unfortunately the fact that a diffusers are also positive reflectors escaped my train of thought until 3 seconds after i pressed send

[@ivanperezokhuysen1788]

that noise reduction in the A tracks seems suspicious to me. also a different tone in the overall ambience of the room

[@odindejong6801]

Ivan Perez Okhuysen it’s actually the computer fan that you hear in the background. Unfortunately on the “b” recordings the fan was running harder.. I didn’t want to do it all over again 😜
