      I will be doing a test tomorrow recording impulses through a plate verb and some vintage gear.
      Does anyone have any experience with this here ? Should i use a sweep or one sample tick ?

      Any tips ?

        I've never done vintage gear but for IRs I always use a sweep

          Yes, did a quick reverb sweep in software , using Voxengo Deconvolver.
          Do you normalize your sweeps to -0.3 when deconvolving ?

          Tested a tick with some eq , seems to work somewhat 🙂

            Can't remember if I use normalization, it's been a while.

                    🙂 really nice stuff. Lot of fun ahead 🙂

                    LOGIC pro X hides an IR capturer with sweep generator and deconvolver, just right click on app and click on show package content and you'll see it.

                      @hisefilo Have you compared this to Deconvolver?
                      I'm using Deconvolver at the moment, but it makes more unusable files than unusable ones 💩

                        @dustbro what is the problem with deconvolver?
                        Btw i am using Reaverb in Reaper, makes test tones and does deconvolving.

                          @lalalandsynth I have to deconvolve multiple time to get a usable result (without changing any settings).
                          Sometimes I'll get an unexpected frequency response or ghost echos.

                            @dustbro just did an IR long time ago and was good. Couple of tricks to get it working since it's not aimed to final user I guess.

                              So how does convolution work with analog gear? I assume you take impulses of every setting (or as many as you can) and then interpolate between them somehow?

                              That last bit always confused me 😂

                                @iamlamprey there is no interpolation. Well there's a couple of model machines out there that take "frames" and apply them in different ways, but convolution is straight(but CPU intensive) maths on a fixed set of numbers (the impulse). So in most situations where the result is dependent on a changing input ( say a desk or a compressor or a tape machine), then convolution is probably not going to help much without first streaming your input(on say frequency or volume) and passing it into multiple convolutions - so expensive and all you did was move the granularity of the interpolation required ( and you still cant have interpolation).

                                  @Lindon I see, thanks Lindon. I suppose it's better to use it as a base then recreate the "sound" with algos/chains instead? I'd still prefer that route to the whole "LTspice recreating the circuit" thing

                                  sorry for pseudo-derailing 🤐

                                    I am making some sweep impulses of reverbs and then use the Tick method to capture the "Colour" of the unit in question, I have yet to test if that method of capturing the colour is worth doing , I need to do some more experiments.

                                      @lalalandsynth my experience is that the sweep will capture the colour anyway - your experience may end up different.

                                          @Lindon actually I meant sweep for time based stuff..reverbs..and tick for comp/eq
