The IR thread

[bmarsh]

I still find myself using the Rosen IR cabs almost exclusively in Reason. I have no phase issues. For clean guitar i use the AC30 cab, Decay full-on, HF Damp all the way down (tweak to taste if needed), and HI EQ @ around 2 o' clock. I also enable EQ on the RV7000 MKII, HP to taste and maybe look for some sweet spots to boost slightly if i'm playing a different guitar than usual. For heavier rock stuff i usually use the Rosen 1960 Marshall impulses @ about the same settings, maybe backing off the HI EQ to halfway and adjusting RV EQ for added "girth".

Got a reverb related question, if anyone has native instruments massive would it be possible to somehow record the response from massive's dimension expander? I mean from what little I know about it, the dimension expander is apparently a short reverb that is used to make stuff have a stereo effect. Would that be possible and has anyone done so?

Hi,

If you are looking for guitar cab and bass cab impulse response (IR) files, you might want to check out my site. I am always adding new guitar cabinet or bass cabinet ir's usually on a weekly or monthly basis in both Fractal Audio & Wav file formats.

Currently I have the following for sale:

• Ampeg B-15
  Aguillar DB810
  SVT 8X10
  SWR Super Redhead
  Norlin Gibson Moog Lab Series L5
  1959 Valco Supro 1606 branded as Oahu Publishing Co of Cleveland Ohio 1X6

Sound samples may be found in the Samples tab of my site, which is Google translate compatable.

If you have any quesions tht the site does not answer, please feel free to contact me.

Are there good real world ones in the reason libary or better ones in the lists?

[NaviRetlav]

We just released the Impulse Exploration 4 and the Impulse Boost Bundle 2.
And for those that want just the free stuff we updated the Impulse Demo Bundle with the new IRs

I sometimes wonder about cab IR's that if I was small enough to live in a 4x12 dimensioned plywood box whether I'd actually prefer the internal acoustic properties of one vs another.

I mean it's not like they are made of tone-woods or anything special and they are almost small enough spaces for the resultant IR's to be pretty much just filters with really short-tails, therefore easy enough to emulate by fairly simple means.

Perhaps I'd need to be a proper guitar player to appreciate the subtle differences in tone over a straightforward bit of EQ'ing with a splash of tight small-space verb though.

Because they are short, would this make them easy to emulate? I don't understand if short or longer IR can be compared for complexity.

A cabinet with speaker does all sorts of things to dynamics, EQ and resonance. Resonance is a huge thing in guitar cabs. And the super fast transients are complex. With just an EQ and compressor that would not be possible to emulate.

Good example is the Palmer Speaker simulator which is a filter, nothing else. It can sound great, mostly on cleaner sounds. But it won't give you the low end resonance of a speaker cab or IR.

Yes, I'm aware that many enclosures are not merely plywood boxes (even though many are) some are ported, baffled and have reflex openings to cater for the high sound pressure levels and somewhat altering the dynamics that are happening in a short space of time.

What I'm questioning though is a static IR can be the best thing to accurately reproduce everything that's going on. Bear in mind that a static IR will not reproduce ANY of the time invariant qualities of a particular cabinet, which you rightly suggest involves EQ and resonance, but only EQ and resonance, which is why I mentioned EQ and a small space reverb (I didn't mention using a compressor btw) to emulate an IR (not an actual cab).

I'm not familiar with the Palmer Speaker simulator, is intended to simulate the speaker, cab or both?

[Heater]

Does anyone have a Strymon reverb and is willing to capture some impulses for the community?

I found some here

[EDIT] I had to remove some silence from the beginning of the files.

The Palmers Speaker simulator changes the speaker output of a guitar amp into a line level signal, both filtered and unfiltered. It's a passive device, at least the one I own, the PDI03.

IRs for speakercabinets are 100% accurate. See https://www.celestionplus.com for some tests. When I am using my tube amps with IR I get the best guitar sound I ever got. It sounds better than any of the old records. Play some old Van Halen and hear how thin the guitar is sounding. Even the remastered version. Today we can get a much better guitar tone I must say.

That makes sense, IR's from the whole post-amplifier stage, including the cab, speakers AND the influence of the mic's (position and setup). I can certainly get that as being an accurate and worthwhile proposition to arrive at via an IR. That's a refreshing point about the improvements in guitar tone today too, as I so often hear people going on about how fantastic the 'old' sounds were.

I am not familiar with this convolution world, thanks so much for the contribution! Thanks for sharing your knowledge with others!

Just for fun I started throwing any wav file into the RV7000, people talking, various sound effects, just cut them down to size in an editor and have fun.

Here's another seller of IR libraries that I just discovered. I haven't tried them yet and I think they're sold on a DVD and not downloadable. They include presets for the Waves IR-1 and Logic Space Designer but the IRs should, in theory, be usable in the RV7000 (or get the Waves IR1 cheap

Quick update about Xtreme samples IRs. I just bought the Lexicon 224 library from them and although the description only says DVD, it was actually a download (which I greatly prefer). The file was an iso image in .rar so, for whatever reason, it is a DVD image file but is downloadable. I suppose if you wanted to burn it to DVD it's convenient

In any case, so far they sound really good and it's a very big collection, 1.5GB uncompressed! So it seems like enough variations on offer to have the right preset for most situations.

So far I have just been using the Waves IR-1 presets as they're very convenient, just one click to load up the impulses.

Hiya. Stefan from Reason Studios here. I don't if it's been mentioned already but in Reason 11, I snuck in a handful of new IRs of my Mesa Boogie 4x12 and Marshall 1960 cab. You'll find them in the RV7000 preset folder. Hope you'll like them as much as I do. I pretty much use the new Mesa (USA) Mix 1 blended with the Marshall (UK) Mix 4 for all my guitar work right now.

No, AFAIK would not work, it is a modulation FX. But you can get the free dim exp from Xfer. Duda tried his best to reverse engineer the Massive dim exp. Soundtoys has a good one too for more width, Microshift.

Free Sony Playstation reverb impulse responses

For this project i used a PS1 model number SCPH-5552 as that particular model (and earlier) includes it's inbuilt reverb algorithms within the CD player. I then made a custom sine sweep file and burnt it onto a CD which i placed into the Playstation. After some trial and error i finally got a result that's on par with the console and gave me great satisfaction!

Many games on the PS1 would take advantage of the systems reverb to help make it's music/fx sound less dull. One great example of this can be heard in the infamous PS1 startup sound! The sound itself only consists of 3 audio files played at different speeds.. but with the help of it's reverb the audio is enhanced and glued together to help present that futuristic sound that we all know and love.

Free to download! Any donations are appreciated

Enjoy!!
