How good is digital room correction?

I use Dirac in my system, wich is a high end one, and it works very very well. I use with my PC. It makes A LOT of difference. I totally recomend it

[@EndstyleGG]

This is basically spot on with my experience, anytime I tried to correct the full range of the speaker, It just didn't sound right, even if it was measuring properly. But when I put all the effort into the sub 120hz area, man I got stellar results, no annoying boomy or overly punchy sound and especially being the same level right down to about 28hz. I currently have GoldenEar Triton 3's and a cheap Behringer amp with DSP built in, but man taking some time to do that improved the sound 10 fold. Hoping to upgrade to a nicer amp and a miniDSP HD in the future, but the sound I'm currently hearing is basically spot on what I enjoy

[@JMJM75257]

dayton audios dsp-lf does the same thing as minidsp at less cost to you!

[@kirkcunningham6146]

This is what I do and it works very well if you take your time. You play a test CD with test tones at each basic frequency through your left and right speakers with the subwoofer off. You calibrate and set the level for 75db @ 1K using an analog SPL meter at your listening position. This will be your reference point. Then play your bass, mid and treble frequency sweep tones writing down the spl levels above and/or below the 75 db @ 1K reference. Anything above the reference are peaks and anything below are dips at each respective frequency. Now you can use a Behringer UltraCurve Pro for example to lower or raise the frequency response. I like using the parametric eq file in the Behringer because the amount of octave adjustments are amazing. This test will give you a general idea of what your room is doing and the frequency response of your speakers in your room. Once you dial in the front speakers, you can test the subwoofer. I use a subwoofer test disc to get an idea of how low it will play at reference levels for home theater as well as peaks which in my case, I have that annoying 50hz peak. It won't ever be perfect doing it this way but you can dial your system in pretty good to taste using the Behringer.

[@Doge317]

My room is really not ideal, and Dirac Live did wonders to my sound. My stereo imaging is much better, its now correctly centered. My bass is now pretty flat and tight and it just sounds amazing. Absolutely recommended if your room is kinda shit to begin with, and you cant put too much acoustic treatments in the room.

[@shyam915]

I second that 🤚 my proac d48r's had horrible bass peaks .. it sounded worse than the cheapest speakers in the market because my room was too small . I ran a trail version of dirac live and it did wonders to the bass and soundstage .. the bass is now dam tight and fast ... midrange and midbass is ultra clean . But the voicing of the speaker has changed a bit ..dats because u evenout the mid's and highs to get an smooth curve . but i can always leave the mid to upper frequencies out of the correction area to make it back to normal . the sound stage i get with dirac has vocals rightly centred with good space between instruments on either aide ... .so its always a win !

[@corystansbury]

Dirac is the measurement software, correct? I've been using REW so far with great results. What do you use for a DSP?

[@hiresaudiocosta873]

The measurement microphone gets positioned in designated places around the listening position both behind and in front, to the left and to the right, both high and low. And the measurement sweeps have to be done in order at the correct designated positions in order for the software to correctly calculate adjustments. It also makes sweeps from only the left channel and then the right. It's not just done from one microphone position.

Totally, its for taking away the peaks and not filling the deep valleys, walk speakers for the least room interaction.

For years I was not a fan of room correction until I tried Audyssey xt32, then I was sold on the idea that it could work well. I did the measurements at around head height across the 3 or so seating positions on the lounge chair we have and I think it did a great job.

[@HiFiInsider]

If you have a large room, consider a line array spk system and use some room correction at the listening position.

[@makzmakz]

He answers the qustion @2:48.

[@wildcat1065]

If you stream using Roon software there is a parametric equaliser built in. I have calculated my room modes in the bass and set up steep band stop filters at the peaks and I find the bass is much improved with no discernable minuses. I probably wouldn't use room correction for high frequencies though. A physical absorber/reflector at the first reflection point is the best answer for problems higher up.

[@alext2933]

Regarding your Mic comments, in this instance (Lingdorf room perfect) you measure at many positions, starting with the main seat. The more the merrier in fact. Not limited in position/s like systems of the past. Indeed, each time the amp tells you how well it has learned the 'whole room' as a percentage.

[@erod9088]

It's great for trims and delays and correction up to the Shroeder frequency. Don't use above that unless you have a really funky room.

[@xrplew1236]

If you make the adjustments in the digital domain before the DAC PREAMP and AMP then yeah it’s going to be a dream. Ideally you’d place the speakers for the flattest response first then fine tune with room correction and use the mic in the seating position.

[@roybertalotto6355]

I Realize this is an older KZbin video. But many of the issues you had with digital room correction have been mitigated with Room Perfect. I was totally against anything that messed with my beloved signal. But Room Perfect is changing my opinion.....

[@dell177]

I spent 1968 running the recording studio at Ft Benning (on the 1st floor of the infantry school). It was great duty for me because they let me do what I thought sb done. The major that ran the sound branch stopped by almost every day on his way up to the Chief of Operations office on the 5th floor, he left his cover and keys on my desk. One day on his way out of the building ge came back to get his cover and car keys but grabbed the wrong hat. I had to go up to the sound section to get something one day so I closed the studio up anf headed across the airborne field up yo main post. As i walked along I started to get salutes from soldiers and officers along with some strange looks. i peeled off the cap and found a majors oak leaf cluster and that meant the major was walking around with my hat with it's SP5 badge on it. That badge was supposed to be flat black but the paint started to flake off revealing the copper base ,metal so polished it up and wore polished copper SP5 badges to denote my rank, I never got called on that when in Benning or Korea - it was my way of rebellling against the army. Another way was wearing a bright orange scarf (signal corps colors) when standing formal fatigue inspection. The major did call me on that and I told him I was signal corps and not infantry he told me I was a PITA and told me to carry on. The effect was pretty starting, hundreds of sky blue scarves with a dozed bright orange ones at one end. IMO the old fatigues were much better looking tha the crap they wear now, desert camo is fine for Iraq but not so much for Korea. The major and I exchanged hats that afternoon, He didn't even realize he had the wrong hat. That major was a good commander and his boss (bird colonel) was as well, as long as you did your job they pretty much left you alone and they took umbrage at any officer who tried to pull chicken shit discipline on their men

[@scottdc6971]

Digital signal processing is the only way to remove room nodes from a speaker system. FIR filtering is pretty transparent to the signal path if it is a good quality processor (something like a AD Sharc processor). Using FIR's on signals lower than 100 Hz is not practical due to the massive amount of delay it takes to process those long wave lengths which makes the whole system laggy and lethargic. The only way FIR makes sense is >100 Hz. If implemented correctly, it's a lovely thing.

[@DodgyBrothersEngineering]

I'd rather treat the room for lumps and bumps first before trying to correct digitally. Just means less physical manipulation of the sound.

[@MrTheNark]

There are techniques to use FIR filters with more filter resolution at low frequencies. I don't know the details but I know that it's implemented with multirate filter banks. Audyssey MultEQ XT32 uses it to put most calculation power to the lowest frequencies, because there the most detailed correction is desired.

[@ThinkingBetter]

I've seen really good examples of digital audio processing improving the audio fidelity but also the opposite. You have to understand what is wrong before you start fixing it. Always try to fix the root cause first. For example, if the speakers have a terrible frequency response with big dips then the speakers are the problem and adding EQ to compensate might create audible harmonic distortion at those frequencies when the amp can't deliver the dynamics at that frequency. E.g. if you have a 800Hz dip of 15dB and you boost it 15dB with an EQ you probably feel it sounds better at low volumes but at higher volumes, your amp just lost 15dB of its dynamic range at 800Hz where you will hear clipping before any other frequencies in the music. But then, if you fixed such problems by root cause (speakers and room acoustical conditions), there CAN be some additional performance gained by tweaking through a DSP e.g. delays and frequency response. Actually a surround setup needs delay settings or you will have serious problems with the sound stage.

[@adelkharisov]

[@progrocker84]

I use a DBX Driverack Venu360 in a very small room (height is less than 5"10'). It drives two Yamaha HS8 monitors + Yamaha HS8S powered subwoofer. Sounds great for video and modest mixing, but I must admit that I am no audiophile. Would love to see the DBX compared with Dirac Live, Audyssey, and other room correction methods.

[@michaelarthurmusic307]

Excellent explanation Paul. I have a Meridian system which only deals with the low end (I can't remember the cut off frequency) and it works very well. In my work as a recording studio engineer, I have used pro audio solutions that require the use of an expensive measuring microphone, and software that averages multiple response tests. Keep in mind that correcting the low end works because it is non-directional. Trying to correct mid and upper frequencies that the room is affecting also affects the direct sound coming from the speakers. This will only work if the adjustments are minor as you pointed out. Thanks again.

[@BTom16]

How sweet would it be if a speaker would email a report indicating there are X problems, Y have been compensated, and Z cannot be corrected. If the report included details of the problems, you could reposition some things in the room, maybe try some different corner treatments, and retest. Might be a setup dream come true.

[@b1zzler]

Audyssey MultEQ XT is fantastic- and that's just the budget version of Audyssey. I have a cheap amplifier, a cheap pair of JBL speakers, and a cheap subwoofer that sound "okay" without correction. With correction, the subwoofer disappears (sounds like bass is coming from the L/R speakers), the phantom center image sharpens up, and the bass sounds fuller and deeper. Without correction, I have to turn down the subwoofer so much that it's basically off in order to tame the peaks, and the upper mids and trebble are way too harsh.

[@philipp594]

I think you want to do it below the critical frequency of the room. Most rooms are like 250hz.

[@ericelliott227]

If a room (like my current one) is really bad as in an acoustical engineer's nightmare, no amount of any correction will help and the only way to correct is to move. For everyone else that has a room with at least 3 walls, carpet and at least two corners, I look at it this way. There is no such thing as perfect in audio. I will never understand the pursuit of such by folks. Will digital room correction alone solve my issues with sound? No. Will set-up alone do it? No. Will room treatment alone do it? no. It really requires all three or at least two of the three to solve some issues. All three will not even get you close to perfect either. In using digital room correction myself for multi-channel audio for some years, I have to agree with Paul. For sub-woofer or sub-woofer placement it works very well as it does for the lower frequencies in the main speakers. As for the highs and high-mids....uh, not so much. For two-channel audio which I will be switching back to in the coming months, I won't use digital correction at all as I feel it will just make more of a mess in that case. In my present case, all I can do is proper placement. If I move and get a different room (making sure it is not even worse than the one I have, if that is even possible), then I will use both set-up and a little bit of room treatment. (Another area I see many folks mess up, trying to turn their room into an anechoic chamber or something.

[@moukiebengal9753]

i have dirac live in my receiver Arcam , tried it many times with calibrated microphone with mic placed exactly in my listening chair sweet spot , then i turn it on and off and on and off etc..... i even played with the stock curve to make it more to my taste , every time i came back to Stereo direct with dirac live OFF it sounded better in my room without the Dirac room correction , so i gave up and now am just listening without it by just placing speakers more accurately and i place diffusers on side walls and rear wall

[@CaptainCrunch823]

I had the same experience with a Denon receiver with the latest and greatest version of Audyssey room correction. I am of the belief that room correction is great for the average consumer who generally won't take the time to dial in speaker placement, distances, window treatments, area rugs, speaker and subwoofer crossover points. Maybe I could see room correction helping for extremely challenging rooms, but based on my experience, my ears, hands and eyes did a better job of correcting issues than the receiver's software did.

[@gurratell7326]

Thats probably because you prefer the nonflattened frequenzy reponse of you speakers/woofer. If you use a custom curve in your dirac acording to your taste it will probably sound better than with it all off. Try it :)

[@moukiebengal9753]

Gurra Tell a already tried

[@hnipen]

I was auditioning Sonus Faber Guarneri Evolution via a Devialet amp trying with and without SAM correction. No matter what I was doing and how I was trying, I consistently preferrred SAM turned off, it was just more natural, and more smooth and more pleasant and musical with correction off. With SAM turned on it sounded like freeze dried music from a plastic box .... no musical pleasure. Seems like with SAM you pay a lot of money to get less musical pleaure.

[@sbrinckoo855]

moukie bengal I really think all prepro room correction is geared towards theater surround then 2 channel. I have a Marantz 8200 and a 7.1 system and when listening to 2 channel always go to direct or even pure direct it’s always an easy choice.

[@66rabidmonkey]

Yup. I agree with everything said. SBIR (speaker boundary interference response) can cancel certain frequencies and no amount of room correction signal adjustment is going to bring them back. Physical room correction is the only thing that can be done for those missing frequencies. The biggest impact on music reproduction quality is first, speaker quality, and secondly speaker placement in the room, and acoustic treatment considerations, which is why sometimes it is just quicker, cheaper, and easier to use headphones, but then you lose out on proper stereo imaging, unless you do some amount of channel crossover to mimic stereo speakers.

Non-Parallel wall/room surfaces as well as corner bass traps helps to eliminate standing waves, phase cancellations & dead spots.

This is why I love the JBL MS-8 processor in my car. For each seating position, it takes 6 measurements for a spatial average at each spot. (you sit in each seat with a set of binaural mics on your head that look like headphones) Then it can optimize the sound for each seat, the front seats together, the rear seats or all seats together. And it works!

[@jdlech]

A dedicated amplifier and speaker system should alleviate much of the problem. Yes, adding 30db to a driver already putting out 90db would be a real problem. No more headroom being the most obvious. But a dedicated speaker system could be set up to do the job. Yes, it's going to be more expensive and more complex. But it won't punish your speakers and amp. I've been toying with the idea for 20 years now, but never took the plunge. I think my biggest problem is that my system is all analog - with digital sources converted to analog right away and then processed. And if I'm going to go digital, then I'm going ALL digital, all the way to just before the amp. Which means replacing nearly everything - a rather expensive prospect. And I can never quite find exactly what I want.

[@4G12]

Nowadays you can do DSP on your PC with excellent EQ software and get excellent results. It's how I make boomy multimedia speakers sound clear and reasonably flat in small rooms with no practical way to acoustically treat. It really doesn't matter that your entire audio system is analogue as long as the DSP corrected signal is sent to your system afterwards via a quality DAC, which could be your motherboard on board sound card or better yet, an external sound card DAC getting a clean digital signal to avoid EM noise within the PC.

[@lrrrruleroftheplanetomicro6881]

Hahaha..can you show us a photo of you when young and with long hair? It would be sooo cooool...cheers

[@chipsnmydip]

First, you need really high quality DSP to not degrade your sound quality for even small eq cuts and boosts. If you are dealing with 10-30db of cuts and boosts, you are certainly going to encounter phase distortion or loss of impulse response (linear phase equalizer) and/or ringing of some kind. And if you are using an analog or DSD source, you are basically throwing any sonic advantages of those formats out the window. I would not consider this a good high fidelity solution.

[@wilcalint]

Is it not true that digital room correction is really in the realm of sound re-enforcement? Church's, performance halls and Movie Auditoriums? Dolby Atmos uses a lot of it. I am lucky to live quite close to a brand new Dolby Atmos Digital Audio ( I counted at least 32 speakers ) and Laser projection movie theater. It's very impressive.

Hi Paul, I do agree with you. I have listened to the Dutch Kii speakers just before they went on sales. I compare them with mine wich are (new) stacked esl57, townshend tweeters, a pair of rel strata2 and a Lectron Jean Hiraga tube amp. So nothing fancy. Roomsize 6m by 5m. What i noticed is that the Kii are probaly measured much better than mine. But... there is something about the 'air' or liveness in the sound wich is different and somewhat unrealistic. It didn't touch me. I think that if a person takes more time for its loudspeaker placement (hobbies may take sometime) and a little adjustmends over time to your room can do little wonders. A bought a Bosch laser centimeter which helps and after 3 months of trial and error, its sounds pretty ok and acceptable for the moment. Good luck and thank you for teaching us dumbo's haha.

[@BlankBrain]

I suspect that psycoacoustics comes into play. I think that our brains are good enough at recognizing room deficiencies and compensating for them, that in most cases we don't need much (if any) additional compensation. My mind seems to be better at compensating for reflections than long-duration standing waves and room resonances. This aligns with what Paul discussed regarding removal of peaks in the low frequency region. I tend to take a minimalist approach to audio reproduction. I think DSP can be used as another tool to synergistically improve LF reproduction. It's not much different than adjusting port length, damping material and enclosure bracing. For those interested in FIR filters, here is a link to a good resource: www.prosoundtraining.com/2013/09/06/fir-ward-thinking-fir-filters-audio-systems/

[@Fergutor]

That doesn't make sense. If that was true then we would not have much appreciation of dynamic range, volume, distinctions from sounds of different frequencies, music would be more similar to hearing white noise than music. I hear perfectly the brutal peaks at 47hz and 126hz and how everything goes away at 105hz and ~230hz in my room (I measured it of course), just as everybody else can, which is the reason room treatment and EQ correctin exist. If you can't hear those kind of problems in your room, is either because the music you play is extremely simple, your hearing system is malfunctioning, your room is extremely good...or you don't have a room haha.

[@BlankBrain]

Fergutor - I'm saying that we need DSP or other treatment at low frequencies, where speakers may misbehave and/or room characteristics strongly come into play. The room reflections at higher frequencies may detract from the soundstage or detract from clarity. I'm sure there are peaks and valleys in the higher frequencies, but they don't seem to be as bothersome to me. Sound reproduction starts at the media, but doesn't end at the ear; it ends in the _perception_. Perception can be altered by experience, training and expectations. I suspect that the reason I can enjoy music recorded imperfectly, reproduced imperfectly, played into an imperfect room, and listened to with imperfect ears, is perception. After doing everything I can reasonably afford to do to optimize playback, I perceive imperfections. As a matter of will, I can still enjoy the music and not become fatigued. At some point, I automatically couple what I hear with my imagination to perceive music.

[@paulphilippart7395]

Acoustic treatment,bass traps, diffusers, tend to be way more effective and often(specially if you DIY)cheaper,DSP has its place though. If most speakers didnt have such poor off axis response...well thats another bone....

[@Simb-l]

Room treatment always trumps dsp correction. But in small rooms when you get a crazy loud bass frequency ringing you physically can't fit a enough treatment in the room. I think for a tiny room like a small office dsp correction is one of the better options.

[@bc527c]

Good one, Paul. In my setup... when I am playing from Jriver I have used REW to make my own corrections, and tried them against the auto corrections etc... and I always end up coming back to no correction. Which just serves to reinforce my commitment to room treatments etc. And I have gotten sorta really close (the sound is really really good)... but the bass mode is strong here and really hard to kill, and my room is not much different in size than your RS5 room, I have no idea how you deal with the bass from 12 big woofers... And the room correction, no, the entirety of the circuitry for room correction in my Integra 80.1 degrades the signal just turning it on, so I have every single feature of the Integra turned off...

[@constantin58]

Maximum desired listening volume is not taken into consideration by any digital room correction technology. If for example a speaker can play very well down to 80hz without distortion at up to ~60% maximum ever desired listening volume, it's a sound quality waste having the room correction set up the speaker at ~160hz and make it play without distortion at max 100% volume if a user never exceeds ~60% volume.

[@russmaleartist]

I disagree . . . I use a DBX DriveRack PA2, and it has done wonders in allow me to tweak my speakers. I have been able to take a female voice that has an awful edge to it and through careful listening and delicate adjustment, cause my speakers to reproduce that voice and other high deficiencies. You can disagree -- don't care . . . it worked for me and another audiophile with an expensive system, and that is all that matters . . . customer satisfaction.

[@hnipen]

I assume you did it spending a lot of energy, using your ears, finding a way that works for you :-) What I am skeptical to is the notion that you can put the speakers anywhere you want, no matter where .... and the room correction will fix anything, like the holy grail to good sound. A lot of the issues come from reflections and room modes that digital correction may not fix. Probably digital room correction is good when used properly and with uttermost care... starting from speaker placements and a setup that is good. Guess that’s what you did here :-)

[@russmaleartist]

No, I did not say that -- the speakers are FIRST set up in order to get the correct imaging . . . preferably in an equally-sided triangle arrangement with the hotspot being slightly in front of one's sitting arrangement. The DBX then uses a microphone at specific measured position points to take readings of all frequencies from where the speakers are situated in the room, along with the room's response. The internal software plots the speakers' response, showing the ideal plot, the room's plot, and the corrected plot. The listener then has the opportunity to refine . . . even customize the response to your liking. Look up DBX DriveRack PA2 on KZbin and watch it in action for yourself. It is made primarily for PA systems like for a stage show, but an audiophile acquaintance showed me how he used it with his speakers which were set up with active crossovers and separate amps, which the DBX recognized and adjusted for in the setup, which can be stored and backed-up. Some may poo-poo the whole thing, which is no surprise; however, I am an avid audiophile for more years than many . . . and I was impressed by the results. Of course, the results will depend on the room, the surroundings, the associated equipment, which all play a factor.

[@bc527c]

While I'm sure you are happy, I wager you would be way happier if you achieved the results with acoustic room treatments.

[@russmaleartist]

Well, the room is pretty good as far as room treatment, but it is a small room and the dimensions are probably the problem . . . can't change that except with a lot of expense. We do what we can do.

I’ll settle this one quick, fast and in a hurry. Digital room correction sucks. Period. You’re welcome 😉

Grouping all room correction system together makes no sense. This video is based on out of date information.

Acoustic room treatment is probably cheaper and infinitely preferable to the cost and quality of DSP required for transparent correction, LOL

You were wearing a wig in the army and you were Christopher Robin? What is even happening?

[@johnsweda2999]

mistake Paul to use DSP go to ASP much better that's where everybody will be going that's what Andrew Jones has done. why destroy a analogue signal and convert it to a digital signal you're just alienating analogue enthusiast. DSP is the poor brother of ASP

[@johnsweda2999]

D Master yes I suppose there's some truth to that but why mess around keep it all the same I still think it could be noticeable at higher low frequencies

WTF ? You were kicked out of Germany during your Period with Giorgio Moroder? Puh, for me this would be a great pain in the Ass... But - do you have still Contact to Giovanni Giorgio?

Just have your damn room built rightr & your speakers in hte right place. Digital room correction is more bs for the bull sitters.
