Best way to “rip” IR from Plugin (Guitar Rig 5/6, Neural DSP nolly etc)

[ApocalypticKatana]

As title says , is there a step by step method out there especially using the AX3’s IR Capture but instead of a real cab it’s capturing it’s the IR of a digital plugin?

I have done 150-170 ms sine sweep with voxengo deconvolver but am wondering if there are other better methods?

You can use the Axe-FX ToneMatch block

Here is the template. It is for Axe-FX II but it can be converted:

Can’t see how this applies to my situation? (Please excuse my ignorance if it does) I don’t want an IR from Fractal’s cab selection

I’d like the wav file for the IR and not stuck to the AX3 as a syx file

That’s probably your best option. If you’re using Logic Pro though, it includes some tools that you might find to be better.

You can run the signal through the Axe-FX (instead of the CAB block). Since you have asked how to use the AX3 IR Capture. However, as GennO has indicated, what you are doing is a perfectly valid method

unfortunately I'm on windows 10

Would you advise what the best IR length is, specifically since this is a digital IR I'm getting it from?

@FractalAudio from the wiki says this..

In my tests I've found that 8K samples (170 ms) is more than enough. I think 500 ms (24K samples) is overkill and if an IR has significant energy out that far then it has too much room in it. The speaker and cab itself are never more than 100 ms, usually much less. Anything beyond that is the room. I personally don't like IRs with lots of room in them. A little bit of early reflections are nice and make things sound less direct but too much room makes the sound get lost in the mix.

There's no meaningful data beyond 150 ms and if there is, it's the room and you don't want that much room."

But this applies to real cabs. not sure how to go about it since I'm making an IR of an existing IR ?

specifically how long the sine sweep should be?

also since I need to leave enough "space" for the target impulse, for example my sine sweep is 170ms my rendered impulse has to be at least a few samples longer than that , say 172ms? why is that? is there an optimal ms of extra length I should target?

Thank you for your time!
