Thanks Aaron for promoting my website and algorithm 😊!

[@aaronshortmusic]

Thanks for making this.

[@rayclark6596]

Cuki79 We all owe you a huge thank you!!

[@DanielPestanaTranslations]

@Cuki79 I’m just getting into this and found your website, which is mind blowing. I recorded two microphones, the ElectroVoice Raven and the SE X1S and my Martin DX1AE (Fishman Sonitone) at 20 cm, 40 cm and 60 cm, the Raven at the 12th fret and the X1S at the 14th fret. I wanted to send you the recordings, but the form on your website isn’t available (or I’m doing something wrong). How can I send you the recordings? Thank you for your work.

[@adsertheblade]

Hi Cuki. Thanks for making this brilliant app. I've seen people using a match eq to get what looks like a similar result. Is this a similar concept, or are you doing a different voodoo under the hood? Thanks

[@EightStringsAttached]

Brilliant job Cuki! Will the algorithm work if I record two different instruments, for example acoustic and electric violin? I can play the same tune but it will never be 100% match...

[@jonallen5280]

This is great! I did it yesterday and found a way to get an even better result after getting the initial IR file. As you said, even the "mod" IR isn't perfect. So I followed your process to get that IR, loaded it into my helix, set the input to USB 1 (the piezo recording in Logic) and output to USB 7/8. Then hit record in Logic and got a track that was my initial pickup recording run through the IR. I then took that track and used the Match EQ Logic plug-in to match the new IR track to the original mic recording. This gave me an EQ compensation curve. I opened the actual IR file, applied the EQ curve, and bounced it out to a new IR file. Loaded that into my Helix, and it's pretty close! With the exception of missing pick noise and such, it sounds almost exactly like the guitar live. Thanks for the head start!

[@HillwinterMusic]

Brilliant! I’ll have to try this out.

[@rombsix]

Great work, brother - you're very diligent. :)

[@11KT11]

Extremely cool!

[@davidpotsdam]

Thanks Aaron

[@CharlesParente]

Thanks, Aaron. For studio one users, there is a built in IR loader plugin called Open AIR that works great. My best signal chain so far inside studio one is Open AIR with a good IR loaded with 25% max blend, then light compression, then EQ, then a second Open AIR with an IR of a very tiny space loaded, with blend knob adjusted to taste. That second IR instance helps best simulate the 'air' which is the space in between the guitar and the microphone. For my playing style this creates about 90% realism compared to an actual mic recording. It's loud in my house all the time with 3 kids and 3 dogs but this way I can record fingerstyle acoustic guitar that sounds 90% like a mic recording.

[@stevesirois3418]

Thanks for sharing this tip, @CharlesParente ! Do you have any specifics regarding the 2nd tiny space IR or perhaps one you can link to?

[@CharlesParente]

@@stevesirois3418 Aloha. For me, the 2nd tiny space IR is one that came from an Apple Logic install (.SDIR file format for their Space Designer plugin--Open AIR opens it just fine...) a few years ago. Called '0.4s_Little Room' but experiment with various small space IRs that you can find. There are tons of IRs out there, many good free ones.

[@JimmyGallowayGuitar]

Great job- easily explained.

[@aaronshortmusic]

Thanks!

[@BucoBucolini]

Tried it yesterday, far better experience than using the NUX pedal to make the IR. I came across his name while learning and reading about IR stuff but I think it was only through your channel that I realized he lets people use it for free. I'm kinda shocked that no major manufacturer didn't pick up his algorithm and put it in their pedal. The guy should be rewarded for this. I could not be happier with the sound I got. No weirdness and unexpected results like with the pedal and only variation is a different mic position. This is what the technology promised but hasn't really delivered and he did with his algorithm.

[@stephan0815]

Many thanks for this, I managed IRs for my Sigma OOOR-28V and my Martin D10e, both sounds great now on the PA. I use my hx stomp and get really good sounds now.

[@aaronshortmusic]

Glad it helped

[@musicandsongideas]

I'm a tech dummy, thanks for showing an old dog what IR is all about and how to use them.😀

[@aaronshortmusic]

You’re welcome. I’ll have more on this topic in the future when there’s more development in the Acoustic IR world.

[@rexomatic8667]

Great video Aaron. I haven’t messed around with IRs yet, really good to get a practical explanation. The difference in sound was pretty amazing. Curios what are some of the less expensive devices that are available that can use IRs in a live settings.

[@aaronshortmusic]

The NUX optima Air is affordable. If you can stretch to an HX Stomp it may be better.

[@hrsif]

I heard that Sonicake Sonic IR does a Gera job. Haven’t tried it though

[@joonasniinivaara5393]

Great video and fascinating topic - I’ve been using IRs to make my (cheap and crappy) guitar sound (almost) better than itself 😅 when I play through a PA - but planning to get a “nice” guitar at some point and make my own IR for it to achieve the same effect - question though: why generate the ir from a signal of playing the guitar instead of a “test signal” (like they do in the amp world) - I think this contributes to the “sheet” effect because playing won’t wake up the high end like a sine sweep would (additionally would wake up “all” the frequencies evenly

[@hellsq]

I like to use helix stomp with IRs because it can blend IR with raw piezo signal, you can always find balanse that you want when playing live. Nux Optima Air is great in cases when you dont need low IR mix, "IR level" in NUX works very strange and even on 0% IR level there is some IR blend in.

[@aaronshortmusic]

Yes having a mix control is very useful. As is the ability to make crossovers.

[@ryanshupe6585]

Hey, I've checked out a few of your IR videos. Just wondering if the technique in this video would allow me to record the pickup on one mandolin and then record something similar on a different mandolin... orr do I need to record the pickup and acoustic versions simultaneously on the same instrument. I know I could use the other technique with ProQ3 and the IR "blip" (or whatever it's called)... but this one seemed easier.

[@jplee3]

This is awesome - thanks for sharing! I have a Headrush MX5 and only recently starting playing with it more and discovering IRs. I knew about that website before as I grabbed some IRs from it but didn't realize there's a generator! After watching your video, I started playing around and am having fun :) One quick question: do you recommend adding any "effects" to the microphone or instrument when recording? In my case, I have a Scarlett Focusrite 2i2 and there are a couple buttons to enhance the sound: "INST" (which relates to the impedance) and "AIR" (which seems to boost the upper frequencies). I tested this out and the first set of IRs I created the output seemed to be 'lower' vs the second set where I had both buttons on. Just wondering what should give the "truest" sound (I'm assuming the former). Also, when recording the stereo wav are you making sure to that the levels on both inputs are as equivalent as possible?

[@aaronshortmusic]

I haven’t tried stereo yet. I’m not sure it’s worth it and I wouldn’t add any effects. Maybe EQ.

[@tnunez01]

Nice video! How can I make a capture of the microphone sound of my acoustic guitar in the quadcortex is it possible? I feel that with the irs there is a lot of floor noise and I don't like it.

[@rayclark6596]

Thanks Aaron, I'm following your IR quest. At 66 I have lost the last half octave of hearing (so I'm not the best person to comment on this) but what seems to be missing is the 12 to 15 k of pick noise (percussion) on the strings. Maybe an EQ adjustment is all it needs? Try using the previous recording, but bump up the 12 to 15 k range for the mic side so that it's on the verge of announcing. Then run another IR to see if you like that version better. Just a thought.

[@aaronshortmusic]

Yes I agree but it’s still not quite the same.

[@SorenAraujo]

Hi Aaron, great content. I've been following the Neural Amp Modeler fever lately, and wondering how useful it could be for acoustic players. Could I ask your thoughts on this? Cheers.

[@aaronshortmusic]

Great point. I wonder if it could be used for acoustic IR’s…

[@gammaraygem]

Hi Aaron. I asked a question in one of your live streams a while ago, and you were so kind to answer elaborately. Had not expected that. I have not much time to follow channels, but I thought I let u know this: My q was about the JOYO BSK 60 amp. You hadnt heard of it. Meanwhile, I got one, and it is great. If all you want is a great sound, and do pedals for looping (it has only 30sec loop) this is an affordable option. I cant say how it compares to fishman ,Bose S1, or other similar priced systems. Reviewers say it knocks them out of the ballpark. I would not know. The battery lasts like forever. I have a Lowden and a top Eastman acoustic (and a bunch of cheaper ones) and I wanted an amp that does not change the sound of the guitar in any way. Not superloud, but good enough for small gigs. (Not for you, I guess..). Weighs like a crate of beer. No problem for me.Very sturdy build, nothing "cheap" about it. And, I like that its an amp. Has bluetooth, but all the smartphone wizardry is lost on me. I am now looking at a soundhole magnetic pick up with built in mic. Fed up with malfunctioning piezo´s (or incompetent luthier, what can I do...). Be well.

[@aaronshortmusic]

I remember discussing this. Thanks for letting me know how the amp is. It sounds like it may be worth checking out!

[@gammaraygem]

@@aaronshortmusic I use an acoustic pre amp to boost the volume, that works for me.

[@jameslifetimelearner]

I’m using Optima Air with shotgun mic, preamp, EQ,next try compression on way in. With Website,all processing in the Box!

[@jameslifetimelearner]

Fabfilter for IR’s? I like the idea of sculpting the tone before tracking.Takes the room out of equation.Thanks - a little knowledge is a dangerous thing!

[@barakados]

Hi, I'm always thankfull about your vids and info🙏, excellent. I wonder what happens if I record my pickup sound and I try to match it with some another profesional mic guitar sound, for example a Pat Metheny solo acoustic guitar I get from his song. Would it work?

[@aaronshortmusic]

In theory it can but it’s a different process and never works well in my experience.

[@barakados]

@@aaronshortmusic Thanks a lot, master

[@MattBrodeurMusic]

Curious if this will work on the Mooer Prime P2. I don't know anything about IR's. But the ones that are built into the P2 are for amps and cabs, not a pickup or mic. But I would like to get some decent acoustic sounds on there. I played around with the Mooer Tone Capture GTR pedal but was unimpressed. I think that is mainly just EQ manipulation.

[@aaronshortmusic]

If your pedal can import IR’s then you can easily take them from the NUX and load them in. Thats why I have an HX Stomp as it’s good for that purpose.

[@martindavidson2071]

Good video. One question though - im not a experienced logic user, so how do i bounce the two files? What does that mean?

[@aaronshortmusic]

You highlight the region and select ‘bounce’ from the menu. If you look on KZbin I’m sure there are some tutorial videos on it. Be sure to select the correct settings that I mentioned in the video.

[@kdakan]

Why not record a single knock on the body of your acoustic guitar, try with different materials and strength, and turn these into different ir's to see which one performs best? And also eq them? The acoustic ir's wav files I tried sound like a single sharp knock or hit or click with the natural resonance/reverb of the wood chamber.

[@KurtCobain2021]

in your DAW input named "pickup", did you switched it to piezo pickup?

[@aaronshortmusic]

I just labeled it that for the video.

[@hoggboyy]

What would happen if you did it with two different guitars, sort of as a way to simulate a different sized guitar live for example?

[@aaronshortmusic]

The way it works is you are trying to match the IR to the pickup. You can do what you are suggesting but it involves a slightly different approach.

[@danswofford]

I did this and have what I think is a pretty good IR that I use in a Hotone Binary Cab Sim pedal. My problem is... I like to play at Open Mics and carrying a guitar, cable, pedal, and AC adapter up front is a real hassle and the Open Mic host dread seeing me coming. So I am back to the piezo quack. Is there a more hassle free way to use an IR?... perhaps an IR pedal that runs on a battery?

[@aaronshortmusic]

Not really and I agree it’s a lot of stuff to take which is why I play stage-ready guitars now.

[@danswofford]

@@aaronshortmusic I found a rechargeable power supply on-line and zip tied my IR pedal on top of it last week. The open mic host seemed to really like it because the cable he provided just connected to my IR pedal instead of my guitar with no further fuss (I had my guitar already cabled to the pedal when I went on stage). I liked hearing the IR produced tone through the PA. I think this will be my standard open mic approach now. 😊👍

[@Cuki-ox2mk]

To get 1:1 you must visit me in France. Lol.

[@aaronshortmusic]

So you feel it is possible?

[@Cuki-ox2mk]

@@aaronshortmusic Well you can do better for sure. What I can solve is the "attack-wetness" problem. Having something more realist. With 2048 pts, you can still have the feeling to trigger sound... the infamous "distant feel". That I can solve. The high end vibes due to the vibration of the strings radiating... I am not sure I can solve it...

[@andrejgregoric1324]

is it possible to use this IR with Aura? just renaming extension?

[@aaronshortmusic]

No. Aura is proprietary.

[@ricjoorg]

So, is this what essentially the Aura solution by Fishman on the Martin Retros is? But using the prewar museum guitars as source and the super expensive microphones?

[@aaronshortmusic]

Yes it’s basically the same process except that they used different guitars which is sometimes called ‘image casting’.

[@ricjoorg]

Got it. Thanks . But I guess you would do, if you had access to those prewar guitars 😄

[@aaronshortmusic]

@@ricjoorg Yeah but there’s an argument with IR’s that it’s best to make an IR of the actual instrument itself.

[@adsertheblade]

Hmm, didn't work for me. Just got a red exclamation mark after changing the name and pressing the play button

[@aaronshortmusic]

Worked for me again yesterday. Should be fine.
