How To Make Your Own Impulse Responses / Convolutions

[@clintonsingh7708]

Been using it in FL for years but learnt so much more from you

[@lodewijkvos]

Thanks, and awesme video once again. I love to use Nature sounds as a convolution, wind and birds give real nice glitchy movement to synth pads. I also like to record city noises and trow them in the convolution for the same reason, just to build movement into the frequencies of the instrument that I'm playing

x100 Sphongle Convolutions Incoming... Awesome Video Dash. I love the way you raise the Eyebrow of "Are you with me on this?". I am over this like a bad rash Dash :)

[@Projektor_music]

Great video, there might be a slight misconception though. I believe that FM and convolution are both a multiplication of 2 signals but in a different way, FM is a multiplication between the playback speed of one signal as it's playing (pitch) and the second signal. But for convolution I believe the multiplication happens between the spectrums of the 2 signals. I.E. the spectrum of the room in which the reverb is measured is multiplied and thus in a way imposed on the signal being processed. I believe these things are different enough to classify FM and convolution as 2 different things... but I'd love to be corrected if not!

[@DashGlitch]

Correct, I think I misspoke, I meant to say they’re similar in that they both use multiplication but not identical in the method

[@Projektor_music]

@@DashGlitch pfff well then at least I'm not going crazy because of this...

[@projectnemesi5950]

Yes, its multiplication in the frequency domain. So a convolution operation on time domain signals is equivalent to fourier transform of each signal, multiplication, then inverse fourier transform of result.

@@DashGlitch If you have not already, I highly encourage you to learn some of the physics behind this stuff, as it will give you some predictability with using convolution in your art. Fourier transforms and convolution are actually one of the most profound connections between geometry and calculus. Treating functions like geometrical vectors.

[@DashGlitch]

I know the theory, but maybe just explained it badly, thanks for the info

[@eliaszerano3510]

Anyone knows a deconcolver for macOS ?

[@Alckemy]

Finally got around to the video… will comment again after I finish it^

[@Alckemy]

Okay so what was the reason you used the sweep instead of maybe a short click with different verbs? Cool video though, thanks for the info^^

[@DashGlitch]

The sweep is full spectrum and allows the deconvolver/convolution system an idea of what it sounds like at all frequencies

[@Alckemy]

@@DashGlitch I missed that, thanks!

[@gameboyz7497]

dam so amazing , ty very much dash !

I have been trying to get an impulse response of Diva's plate reverb for ever and even after watching this vid I'm still struggling XD You can't load a sample into it so I tried to make a sine sweep in the synth itself by doing a portamento glide from 20hz to 20khz, activating the plate module and bouncing it out. Unfortunately all I get is an impulse that sounds like a sine sweep lol. I've spent a solid year trying any and all reverb effects plugins to try and find something similar and absolutely nothing comes close to it. Load the preset HS Chango Clique and toggle the short plate reverb on and off and you'll hear exactly what I mean. It's super wide, super warm and sounds like the most realistic space I've heard out of a reverb. I just wish U-he would release it as an effect lol. If you're up for the challenge I'd love to see if you are able to replicate it or capture it. I honestly think it's the golden goose of plates.

[@DashGlitch]

you need to render 2 files, one with wet 100% and one with wet 0%, put those into the deconvolver

[@Super-id7bq]

@@DashGlitch Interesting. I tried that but still had the weird pitch scaling effect. I assume the test tone is the one that should be dry? I'll give it another shot. Maybe I scuffed a step. Thanks.

[@DashGlitch]

@@Super-id7bq Correct, double check the sounds are identical on both passes, biggest issue might be random phase in the patch

[@Super-id7bq]

Awesome, thanks for the help! I shall give that a try!

[@francismcfadden3305]

Dude fucking awesome. Subscribed

[@Epic501]

Fun fact, another way to take an impulse response out in the real world, instead of a loudspeaker playing a very loud sine sweep, is just to fire a gun!

[@lilDaveist]

Fun fact: Thats not true.

[@DaddaPsy]

'Murica *uck Yeah!

[@Epic501]

​@@lilDaveist Lmao why would anyone bother commenting that with absolutely zero knowledge of whether that's true or not? Something tells me you aren't a sound engineer. Recordists have been using firearms, starter pistols mostly (for obvious reasons) to create impulses for decades. The entire subject of this video, deconvolution, is just the process of removing the time aspect of a sweep, and combining every swept frequency into a single white noise impulse. This doesn't need to be done to a gunshot, as it already is a single white noise impulse, just a less accurately reproducible one. You've no idea what you're talking about, why even pipe up and be rude?

[@lilDaveist]

@@Epic501 mostly because I study this shit in university. Firearms and claps and such act upon high frequencies. If you want a proper Impulse response, you need a tone with an even frequency content. Why be rude if you dont know where I am coming from or what I am refering to?

[@mylogify]

@@Epic501 What the hell is a starter pistol

[@GGSAfterburner]

Sad it isn't available for mac :(

[@mylogify]

Does the IR Utility in Logic Pro X works similar way as Voxengo Deconvolvar? Or are they completely different?

[@ClintMoody]

@@mylogify it's similar, but not the same because with deconvolver you can use your own pre-recorded impulse responses

[@CortlandMahoney]

hello, I stopped watching halfway through because the cover image of this video got my click; but your content does not match the cover.

[@DashGlitch]

But I show how to make custom impulse responses? or is there a misunderstanding?

[@Super-id7bq]

What are you talking about?
