Great Video. Thank you very much for taking your time to walk everyone through REW. Please keep doing the videos.
That was the best REW tutorial Ive seen. I wish I watched this one 1st. Really, I think this is the only video you should watch, then play with it.
And the best advice ..... "play with it". I watched a ton of videos and a read a bunch of tutorials. At 1st, I was overwhelmed with data, options and conflicting advice. But after a couple weekends, I almost looked like I knew what I was doing, lol. I got it down now, but this video definitely stepped up my game.
Thx for sharing.
This is a great tutorial, I will use it soon when I receive my mic 🎤 to tune my car audio. Really, this video is very helpful
Absoultely awesome! thank you for this, lots of great information especially as a beginner, this is incredible!
brilliant tutorial - lots of thanks from south africa
This videos helped alot i understand how i can use this to tune my car. I just installed a zapco dsp amp and ive never tuned b4 but now im learning so much and almoat ready to give it a go.
Go to my channel playlist and look for live tuning sessions, that might help you even more😉
Thank you! Looking forward to watching more :)
thank you this was great!! :)
Very nice video. Please do a beginner tutorial RTA for helix dsp Software. Old version no problem 😊
Great Video my friend
Excelent Video, Gracias.
Thanks for the video
Thank you very much
Excellent video! I have one question though. How do you know what are the best cut-off frequencies for your speakers? If I have tweeters, mid-range, woofers and sub-woofer. Where can we get reliable information for which are the better frequencies each speaker should be run at? Mine are Audison speakers and they don't have a datasheet or anything that explains it.... Thanks man!
If you want to do it properly, there are a few things to have in mind. I have a few videos that might help you. First of all check out video about crossovers as the slope deretmines the ability to manage excursion:
th-cam.com/video/08JYyHCE3jU/w-d-xo.html
Then watch the videos I did on tweeter and mid distorsion testing, as distorsion is a good indication of a crossover point:
th-cam.com/video/L5cKaVXEayg/w-d-xo.html
th-cam.com/video/xGGc03XO7ok/w-d-xo.html
And finally, crossovers will be dictated by the cabin of the car based on tue frequency response. You can see how I choose my crossovers here:

I would love to see the same kind video for helix software

Thanks!
Hey,
Thank you for posting this video, it seems really helpful.
I have a question, are you using focusrite audio interface if we want to change the eq settings that we got from measurements how can we apply to our audio interface?
You apply the EQ to the DSP, not the audio interface.
Nice video! Just brought a Focusrite solo and Daytonaudio Emm-6 . Tried to set up with REW but couldn"t make it . Not sure whether i need to loopback when testing ? Hope that you can make a video step by step how to do it . Thank you
Try this:

Ok 😊
Hi sir ,already watch your recommended video . Now I have a few questions . Should I connect a loop back cable from input to output ? 😅 how to check whether the mic is working ?
Hi, nice video for a person who are beginners to using RTA. Want to know whether we can use correlated or uncorrelated pink noise for measuring the drive response.
We use corellated.
@@RAW-CAt okay
why is my calibration file not moving to the calibration folder, so when the drop down from my task bar shows none, where is it, how can I get to move the calibration file
When measuring a frequency response curve, can I determine maximum and minimum limits for a pass or fail judgment?
Hi @RAW-Cat Some of your videos are now mentioning tuning for customers. I'm in the UK and struggling to find someone with REW and Audiotec Fischer PC-Tool experience and wondered how I can contact you to become a customer!
Sure, find me on FB or email rawcaraudiotuning@gmail.com
Hello
If I take all the measurements and I send to you can you do the settings for me?thank you
Thank you. Can I use umik1 focusrite
No, umik is a USB mic. You need an XLR mic for focusrite. Something like Dayton EMM-6. Might want to watch my video "all about measuring microphones"😉
Great video, I found this very helpful. For some reason, if I save the pink noise file to usb, my head unit won't play it back, it just says no music files
Your head unit doesn't read that file format. Convert the pink noise into mp3
That's what I thought as well but, I manual says it can, only not with MTP@@RAW-CAt
when taking measurements with generator and RTA are those done before any electronic crossover is applied in the dsp? I tried it after and it seems that my slopes when using rew eq were too steep to match house curve.
I take initial.leasurements with no crossovers. The only exception is tweeter, I put 1000Hz 24dB crossover for protection.
@@RAW-CAt
Thank you for the quick response! I went back and did the measurements again with much better results this time. I've got some interesting issues going on still as I am learning the procedure. I have to give you many thanks for the time you've taken to make your videos. These are an incredible resource for those of us attempting to learn about tuning!
Great tutorial, interested on trying REW, but i just have Behringer XENYX302USB & ECM8000 on hand, can i use it as interface and output & input set up?
Sure you can. You can use any interface and mic combination with REW👍
@@RAW-CAtthanks, so which channel input for loop-test, mic input channel or 2-track input?
@@thomaschieng9828 it doesn't matter, as long as you route the I/o in rew correctly.
Really helpful.. good job.. I would like to learn phase correction and time alignment by REW.. can you please help... Thank you.
I personally use HolmIMPULSE for that. Might use REW later on, not sure yet.
Thanks for the video. How do I get my generic EQ sample rate to show 44.1 like yours? Mine shows 48.
Might be the settings in REW? Where you chose the sample rate of the I/O.
Can i use REW app for alpine pxe 0850x dsp tuning
You can use REW with any DSP. The EQ 8mport won't work though, you will have to enter each EQ band manually.
So when we are doing the auto eq portion in rew and you talk about how you can export the file directly into your helix. Well I can’t with my dsp I would have to manually input the values which is fine but what happens to the remaining bands that are still present on my dsp ? You would basically modify the frequency bands within the preset 31freq on the computer ? I guess my question really is you showed only 6 bands of eq in that example but I’m just wondering what it would look like when I’m imputing the values and sort of spacing the bands apart if you catch what I’m trying to say ?
With fully parametric EQ there is no need to space anything out. You can use as many EQ bands as you want, it can be 6, it can be 15, it can be all 30. Using graphical EQ is slightly different though.
@@RAW-CAtthanks I just started to play with it and then it got more easier to do. I just don’t hVe the luxury of exporting the txt file like you do so I wanted to be sure that it didn’t need to be in a specific order to not go back n forth in wasting time over bands needing to be organized or not. Thankfully they are just as you said and it doesn’t seem to care what comes when
Sir wants to know the increments can you please tell us how to set that and what is effects if we choose wrong or right
With small increments, you see too much cariance and can't see the whole picture. With big increments everything will look artificially flat even if it's not. 5dB increments are optimal.
On my rew is missing ‘HOUSE CURVE’ how can add?thank you
What program do you use for timing?
HolmIMPULSE
So you use this to eq and import to a helix dsp, do you not find their auto eq not as accurate? Seems like it would be easier there...
I find REW more flexible and fits my needs better. Especially if I want to make some manual adjustments that auto EQ doesn't want to do.
talking about different mics at the beginning you should mention, that TRRS mics are not suitable to use on windows unfortunately. i have imm-6, the budget one, and i had a bad time trying to tune using it on windows, as it does not capture below ~100hz and above 8k :( its a windows fault. i disabled all enhancements and other stuff, still no luck. there are similar topics on the forums about this issue. Works just fine on linux rew though.
I use tue same mic, however I have it pluged in into an external USB soundcard for like £10 on eBay. Maybe try that?
Is pink periodic "correlated" ?
It can be both.
So audio tuning start with: 1.take individual speaker frequency response with Rta average.
2. Find the cross over point for each speaker with house curve.
3. Fine tune each speaker frequency curve
4. Check phasing and time alignment.
Please correct me if I miss something or wrong. Other questions are: each speaker play at different dB bcz of different sensitivity. How to make sure they all play at same dB? Any place for us to get house target curve for beginning like us.
3.
Between 3 and 4 you do level matching, that is making sure that every speaker is playing at the correct volume. That is based on individual target curves. I make my targets using Jazzi's tuning companion. You can watch my series of videos called "Emma tune", there are multiple parts and goes through the whole process.
Ciao...ho seguito tutti questo video,davvero molto interessanti e intuitivi.
Avrei una domanda però,alquanto strana forse che magati puo essere banale.
Una votla che il programma fa le correzioni e ti genera tutti i filtri con le relative modifiche da applicare successivamente al equalizzatore di un sistema audio,che siano dsp o altro,mi sono reso conto che nel mio caso al interno del mio dsp non e presente un equalizzatore master....cioe un equalizzatore generico che fa il totale di tutti i canali.
Per ogni canale e disponibile un equalizzatore a 32 bande...
Per i due canali dei woofer,che oltretutto posso anche separare e dunque avere un 32 bande flat da modificare per ogni woofer...
Altri due dei medi e altri due dei tweeter e un altro del sub...ben 7 canali con ognuno il proprio eq a 32 bande.
Qualora ad esempio devo applicare una correzzione datomi da rew a 4541hz applicando un -6db,in quale equalizzatore di quale canale dovrei applicare questa correzione?...in un solo canale del tweeter di sinistra o destra,oppure in entrambi?..e qualora questa frequenza la tocco anche con i medi,devo anche procedere a fare la stessa correzzione nel canale dei medi?..ottenendo la stessa modifica in 3 canali diversi che toccano quella frequenza....
Ma non si rischia cosi di avere sovrapposizioni o doppie o triple attenuazioni?..ci fosse stato un eq master il discorso sarebbe stato diverso.
E comunque anche hai woofer che lavorano fino a 300 hz se comunque modifico frequenze alte che non tocco dei microcambiamenti audio si colgono comunque.
Dunque in quale cabale devo applicare la modifica ad esempio di 4000hz -7db medio o tweeter?..come lo capisco?
Oppure devo fare una misura per ogni canale,correggerlo e applicare una correzione diversa canale per canale? Pero in questo modo possono crearsi degli artefatti,dato che suonando uno alla volta posso apparire doverse risonanze ecc ottenendo cosi correzioni diverse.
Credo che il giusto da fare sia appunto misurare e correggere la risposta on frequenza generale,ma devo purtroppo procedere canale per canale
The most correct way to do this would be to have a house curve that is specific to your preference. For a quick adjustment you can apply EQ to the speaker pair, that play that range. In your case 4.5kHz would be for both tweeters. When you have the final frequency response dialed in, you can make a new house curve and Individual targets. There is a lot of playing around. Or as I mentioned you can use input EQ if your DSP has that.
Did you have pdf this tutorial?
Rew has a "help" file where you can find much more than this information.
Nice video. But no information about sound card calibration? Don´t you need it?
You can do it, but it's not really necessary.
Aciu!
