Beginner guide to Car Audio Tuning with REW

[@kewlbug]

Be careful “boosting” those dips. I’m new to REW but from what I hear, dips can be (most likely are) cancellations caused by your room/car. it’s only gonna cancel harder. And you’ll just be wasting power. And/or ruining your speakers. Better to cut peaks. Speakers not in a system don’t usually have a giant dip in their natural response.

[@CasualCarAudio]

I need to update this video. I have learned from my mistakes. Never boost more than 6db or the DSP can clip. I plan to redo this video I’ve just been very busy with the family and 2 jobs etc

[@kewlbug]

@@CasualCarAudio did the auto eq and punched in all the values to my computer setup and wow, It woke the speakers up! sounded great, but I could tell they were struggling. Still gotta do it right. Always learning! gonna play w the car sound soon. (when i get time...same thing)

[@ssullinger916]

Is there a reason for giving a boost at 32 and 40 Hertz when adjusting the midrange driver?

[@kennethmoran4600]

If you boost certain frequencies by 6db in the parametric eq and cut the overall channel decibel by 6 db does it offset the boost and keep the speakers where they need to be with set gains?

[@wadephillips6052]

Different ways of doing things, I would have raised the gain in the mid amp slightly so I would cut in the EQ and not boost as much. Sometimes boosting clips the ch on the DSP.

[@colbylaro9361]

But he is adjusting for frequency response not power.

[@ssullinger916]

Yes but boost or Cuts in the frequency response changes the overall SPL of the system

[@gyreshahart6459]

Gains = rail voltage not volume knob

[@adleneamir4068]

Hello can you make a video about measuring technique, how to place and where placing the mic

[@ebling24]

You used to have a video that showed setting up time alignment with REW and I can't find it for the life of me. Please let me know if this video or guide is still available. Your videos have helped me immensely. Thanks!

[@CasualCarAudio]

I removed it because that method was a bit criticized for not being correct. I would recommend following this guy he's amazing: kzbin.info/www/bejne/aH2YpWR3pM90nq8

[@ebling24]

@@CasualCarAudio I appreciate that but the the method was sound. I've tried the nulling technique before but it's much easier to see phase cancellation in REW. Thanks for the link! His guides are amazing but I don't have a mic with loopback so I was going to try and use your method. The ir response in REW is a little wonky.

@@CasualCarAudio Thanks so much!

[@joaoalmeida9411]

Can you try to move the mic slightly and remeasure again? You might be incorrectly equing some phase issues.

[@cencao5045]

I remember that your homepage has a lot of videos, why all of a sudden these are the only ones left

[@clydesharman2053]

Thank you for the video I think the trickiest part is being sure REW settings are correct which without this video I would have never figured that out. I do have a ? When you run pink noise where do you place the mic? Right at the speaker? Or from the listing position?

[@ssullinger916]

That is definitely been my issue before watching this video is having the preferences in Rew setup the correct way. Thank you!

[@TheLayinLo]

Yeah, me too. I was beating my head against the wall until I finally got them figured out. Now I can even test TS parameters and be within 1-3% of what DATS gets on a speaker. Thanks for easy to watch and understand videos. You sir, are a gentleman and a scholar and should my first born be male, he will be named in your honor.

[@mariouslm]

You can import the rew filters directly into helix dsp by pressing the r key after they were exported and saved from rew first. This would save a lot of time.

[@itsZiz]

How? Exporting from REW defaults to a REW file type, where as the Helix DSP software doesn't accept it.

[@mariouslm]

@@itsZiz look at this video from Appicela Auto sound, hier in this link is the video.... kzbin.info/www/bejne/p4TRZ3h7gMegh7c

[@lorenhoward8178]

@@itsZiz in that menu it defaults to .atf or whatever but you can select .txt. Just export the eq settings as text out of REW.

[@andrekrausz2407]

Thanks for the video. But at 2:45 you explain nothing about whatever you recorded. So I had to go elsewhere to get that bit of beginner info.

[@surrealartphotomanipolatio5271]

When making measurements to set delays between the speaker and the listening point, should the measurements be taken from the grille to the listening point? or would it be more correct to remove the grilles and take measurements from the listening point to the base of the speaker cone without the grille?

[@onesikm3]

Did you learn by now that you could export your eq tune file directly from rew if you just clicked save as .text file in the eq section and upload the file directly to your helix dsp ? That I wish I had 😢

[@KillerBeez1]

Im sure you've learned a lot since you made this and it's a good video. But instead of doing all that manual boost, if wanted to boost so much which is not recommended, in the target setting you can do max boost more than your value of 3 and it would of automatically boosted to target. Thanks for the video.

[@atriusvinius319]

When you boost EQ you bring in distortions in the sound.

[@claytonmckeon9872]

Not in the digital realm

[@anggarrahudhi8403]

please tell me the set up of the tools you use. microphone and so on?

[@ytnimal]

Great Tutorial. Learned a lot from this. Thanks. What was wrong with the mic technique you used?

[@derekhallett6946]

Silly Question here, are you sitting in your car doing this? I'd rather not sit in my car to do this but I can't figure out another way. I'll be attempting to replicate this entire video using REW (keeping your post-video edits in mind) going into a set of VXi amps.

[@danielgarcia3452]

Dónde puedo conseguir ese archivo que usas para las curvas objetivos?

[@jsnichols1]

Great video! One question about EQ of drivers together (L&R tweet, L&R mid, etc): when making adjustments to EQ does it make a difference which side (L or R) you boost/cut frequencies as long as a desired result is achieved? And do YOU personally EQ them together in pairs or is individually good enough? Thanks!

[@felixmedrano8208]

You EQ one, then EQ the other to match the first one.

[@beherit98]

hi, really keen to watch your video and learn. but the lack of volume is really not helping.

[@Sku11Leader]

Where can I find that background?

[@casemods]

Would be nice if this was uploaded with a higher voice volume, more in-depth instruction/explanation, and without a DSP. Or perhaps a more noob-friendly version...a lot of this video is difficult to follow and just makes me want to give up trying to do this.

[@LuckyyTheDog]

Video was good, you just gotta learn the basics before this video.

[@Leysner77]

I saw the jl dsp with a rta function in jl dsp software ..

[@Leysner77]

is this also posible when you have a passive filter setup ?

[@chrisselke449]

Don’t boost if at all possible. Lower the mids hp filter then yoi don’t need to boost all of that.

[@Luca-ib5br]

Great video!

[@janiss9999]

Hi are you sure you have to use mono pink noise for measuring? Because i was using correlated pink noise. That mean is stereo?

[@CasualCarAudio]

Use mono pink noise when tuning individual channels. Use correlated when measuring more than one speaker. If you use uncorrelated with multiple speakers you will experience cancellation.

[@janiss9999]

@@CasualCarAudio thank you very much. Is there any other rule u need to know about meassuring tweeters for example? Are you always using 90° calibration file?

[@CasualCarAudio]

@@janiss9999 always use the calibration file that comes with the mic you purchased. I have the UMIK-1 and there is a website by miniDSP that provided the calibration file based on the serial number on the mic.

[@janiss9999]

@@CasualCarAudio i have got umik 1 too but they have two calibration files and one of them is 90° and there is one more.

[@LuckyyTheDog]

Use 90 when you have rear speakers. Place the mic facing the upwards.@@janiss9999

[@mixie9842]

What does achieving a flat curve across the various components mean ? Does it mean that irrespective of the frequency being played the level will be same across the speakers ? So something like studio monitors with reference sound ?

[@KGReef]

It means that the frequency being played will be played at the intended volume without being boosted or nulled by a terrible frequency response over all. It won't be "colored" by peaks and valleys in response.
