The best Impulse Response [IR] sites

[fmr]

I am not sure what do you mean. If it's like a saw wave or a single note of a synth then this is not what I said. Because saw wave or a single note is not corresponding to notes frequencies. It is corresponding to harmonics of a note. I need frequencies of all of the notes "C, C#, D, D# etc.", not harmonics of a note. Google for - notes frequency chart - this is those frequencies response I am talking about.

What are you trying to achieve? Convolution doesn't work that way, AFAIK.

I'm pretty much aware of note names, their pitches, etc.
But I'm afraid that what you want isn't possible then. I mean, sure, you could put together a stack of notes and then load the resulting bounce into an IR loader - but all you'd get is the response of all notes at once.
It would possibly work with a frequency based input filter thing, but I'm not sure something like that even exists. And it'd only work for monophonic material by the nature such a filter would have.

[Sascha Franck]

But fwiw, in case your music is centered around one key, try to load a longer impulse of the keys root note (ideally using a somewhat "interesting" sound) into your IR loader. Very interesting sounds to get that way.

Please see my attached IR example in the original post. It works. Not perfect but it does.

I am not trying to use it as a reverb or ambience. It's rather like resonator/colorizer. It also works a bit like sound dispersion.

wouldn't that just be a stack of sines 65.41Hz, 69.3Hz and so on? That then becomes your IR

The amplitude will be inconsistent because the signal stack is a bunch of sines which is a complex signal with lots of beat frequencies and the amplitude all over the place. You could see that easily enough as a wveform in your DAW If you want a sustained effect you will have to do them as individual sine IRs and then mix the result
A stack of tuned comb filters might be the way to do it - chromatic resonators

Yes exactly. But it's easy to say and appeared to be not easy to make. There should be some trick how to fade in/out the sines so they would be as short as possible. So I thought maybe somewhere it was done already. Good idea about chromatic comb filter, but I never heard of such. If someone knows such VST please PM me.

P.S
[UPDATE]
I attach example of what this kind of IR can sound like. First goes dry white noise, then it goes through IR type 1, then through type 2, then through both.
You can hear that type 2 sounds especially noticeable that those are like notes pressed all at once.
Then goes synth sound the same way. [DRY][dry+type 1][dry+type 2][dry+type 1+type 2]

So maybe now it is more clear why I say this thing is rather for digital synth stuff.

Even so. To use the impulse as a resonator, you don't need (nor am I sure it would be even useful) to use an impulse for each key. I would pick several impulses, and try each one in several notes across seral octaves, to check which one gives the best result overall.

The way you are trying to do things, you will end up with very uneven and unbalanced results, IMO.

[Sascha Franck]

I tried your IR, @arseniy2. Doesn't do much that couldn't be done with other things, IMO. Yeah, it does add a little kinda resonating thing, but I'm not sure what I'd use that for.

[Sascha Franck]

Fwiw, here's something I recorded for "demonstrational purposes" a whole while ago. Apart from the silly tom loop, all you hear is one track played live. The guitar is running through an IR that is nothing but an overdriven A5 chord.

what's the difference in a mix verses regular reverb ?

ir samples use a ton of memory too imo

- You can use "real" rooms as your reverb.
- You can use pretty weird IRs, offering results not much reverb units would deliver.
- You can kind of create your own reverb "algorithms" by manipulating IRs. Or by recording your own. Like the very sound of your very bathroom? Fine, just capture an IR from it.

Nah, not really. In these days, RAM usage can be considered pretty much a non issue.

Apart from all that, IRs can be used for all kinds of different things, using them as speaker simulations probably being the most popular one.
I also like them for drums, you can for example kind of superimpose the resonance of, say, a tom over a snare which might be too thin. I often find this to be more organic than drum replacing.

Some great IR's in here. Amazing resource!

Also, acoustic guitar body IRs are great for adding some resonance to DI recorded acoustic guitars, or even a bit to electrics, to give a kind of hollow-body feel. Some free ones in this thread;

https://www.gearslutz.com/board/music-c ... -body.html

If you're feeling adventurous you can get a nice mandolin emulation by using a capo on a 12 string acoustic at about the 7th fret, recording it DI then putting it through one of the mandolin ones. Stonehenge...!

3Sigma Audio also do a range which are quite cheap and offer a lot of variations of IRs of individual high end guitars.

The one I use, VSL Hybrid Reverb's folder for impulses has a whopping 12.5MB
Their regular Convolution Reverb has 36MB worth. 36 of them.

You can put anything in it, but I'm using it as 'regular reverb' because of its sound.

Yeah, I use acoustic guitar IRs a lot to get some jazz box sounds out of a solid body, sometimes slightly mixed in, sometimes even parallel to some cab IRs (I know, it's not what they're meant to be used like, but who cares...).

For me, IRs are almost a godsend. Well, in fact, they have been for over a decade by now already as I already recorded my "traditional" amp setup via DI (from the speaker out, using the speaker just as a load and for monitoring) ever since IR loaders and cab IRs got decent.
