4 Superb Impulse Response Reverb Packs To Download

I am a big fan of convolution reverbs. I use them on every tune I make. There are some phenomenal donationware packs around for download these days.

I wanted to put together a little resource for you guys with my favorite impulse responses. I will also briefly introduce the original units and tell you about my favorite presets in each pack.  

You know I always go on about quality. I’ve gone through a lot of impulse packs in the past 5 years. The packs I’ve chosen here are all made with the highest standards. I’ve also designed the selected packs to complement each other content wise. With these packs, I feel like I don’t need much else.

Here are the sets I have chosen:

  • Bricasti M7 by Samplicity
  • Eventide H3000 by Signal to Noize
  • TC Electronics M5000 by Signal to Noize
  • Lexicon 480L by Signal to Noize


All of these packs are donationware. I am not affiliated with the creators of these packs in any way. Please show respect for the hard work and attention to detail that has gone into creating these great tools and making them available free of charge. I’ve donated and I hope you will too.


Convolution? Impulse?

A quick introduction to what this is all about… If you’re familiar with this stuff, feel free to skip!

Convolution technology is used to capture ambiences and reproduce them on the computer. Without getting into too much technical detail (honestly, I don’t even know), an impulse file is a short burst of audio recorded in a real space, or in this case, through a hardware reverb unit. A convolution reverb plugin then uses this impulse file to determine the properties of the reverb and transform those properties onto any sound you are feeding into the plugin. Convolution technique can be applied to just about to anything from reverbs to EQ’s, compressors and preamps. But we’ll stick with reverbs here.

In short, convolution is a way to get the sound of some over-the-top-expensive hardware equipment inside your computer, and at a very affordable price (or even free).

What’s the catch? Flexibility. Convolution technique is somewhat rigid as it is based on recorded samples of the original source. Therefore a convolution reverb doesn’t allow the sort of editing and adjusting of the properties as you get with a conventional reverb unit. Now, most convolution reverb plugins do have some editing capabilities. But you should keep the edits to the minimum. Editing easily tends to destroy the integrity of these fragile impulses. Of course you are free to experiment. Whatever sounds good is good. But in my experience, with convo verbs it’s best to just look for an impulse that works as it is, with minimal to no editing. This preserves the sound of the original source.

There are differences between different impulses. For this post I’ve compared two different M5000 packs for example, and the one featured on this post is clearly better. It’s good to understand that convolution is still only a reproduction of the real thing. The quality of the outcome very much depends on the execution. However convolution can sound pretty damn good when done right.

Popular convolution reverb plugins include Altiverb, Waves  Ir-1, Space Designer (Logic Pro), SIR, Voxengo Pristine Space, Steinberg REVerence (Cubase), TL Space (Pro Tools), Convolution Reverb (Ableton Live) and Vienna Suite Convolver.



Bricasti M7 impulses by Samplicity

Bricasti M7 Reverb

The Bricasti M7 is a revered modern unit that offers fine classic reverb sounds. It has been called “the future of reverberation”. The price of the basic unit is around 3600 EUR  (4900 USD). And that’s without the remote which costs another 2-3 grands. Now there’s something to think about.

This collection by Samplicity includes 136 presets from the M7. These are traditional reverb sounds that sound very smooth and realistic to me. These sounds work well on many kinds of material.

You know sometimes you like a particular reverb sound but it doesn’t seem to sit well in the mix? With the M7 that doesn’t happen as often. Of course you still have to find the right presets, but my experience with these impulses is that they are very usable and just seem to blend effortlessly in the mix while providing heaps of depth and dimension. Try them out.

Eventide H3000 impulses by Signal to Noize

Eventide H3000

The Eventide H3000 first saw the light of the day in 1988. It’s a multi-effect unit that does a lot of wild stuff and these impulses reflect that. Unlike the Bricasti M7, these sounds are made for experimenting. Whenever I need to come up with an unusual twist for drums, the Eventide H3000 impulses are a great place to start.

The Eventide H3000 has been used by The Edge/U2, Stevie Wonder, Brian Eno, Prince, Eddie Van Halen, Dave Pensado, Richie Sambora, and the list goes on…

A couple of personal picks:

  • Try the “Mod Factory/h3000, 833~ethereal (570)_dc” setting on hihats or minimal techno drums… Huge!
  • Also the “reverse gate” ones in the Ultra-Tap folder are among my favorites.

By the way – the guys who made this unit since started Soundtoys and are making some bad ass effect plugins now.

TC Electronics M5000 impulses by Signal to Noize

TC M5000

The M5000 by TC Electronics is an another classic multi fx unit. I’ve had the chance to work with it in the past, and I can tell you from experience that it sounds silky and lush.

This is is a very versatile collection with 96 presets. There is something in there for every situation. For me it especially seems to excel with ambience/chamber type presets. A couple of my favorites include:

  • “Revcore-1/New Booth” – I’ve used this one on the drum bus for countless of tunes. More often than not.
  • “Reverb-2/Nuclear” – crazy long and dark verb. Great for techno.

Lexicon 480L impulses by Signal to Noize

Lexicon 480L

The Lexicon 480L came out in 1986 and at the time they cost more than some cars. Come to think of it, they probably still do.

For a long time the 480L was the standard by which all other processors were measured. These sounds are the classics of the classics, used on countless of popular (and not so popular) records. They are brighter and a bit more aggressive than the Bricasti for example. Draw for the 480L reverbs when you need something that strikes out.

A couple of my favorites:

  • “Wild spaces/Inside Out” – great pumping when the tempo is right.
  • “Random hall/Random Well” – another very nice pumping reverb.

Tips for working with impulses

  • Make custom presets of your favorite impulses. This way you won’t have to look for the impulse files on your hard drive every single time. I kick myself for not realizing I could do that until recently.
  • Don’t worry about sample rate of the impulses being different that the project you’re working on. Use the impulses with highest sample rate. Your plugin will take care of the conversion.

Enjoy these fine sounds and please donate to the creators!


What are your favorite packs?

While these packs provide plenty of ammo to work with, I’d love to hear about your favorites. What impulse packs (free/donationware/paid) do you like to use and how?

Also I am being curious – do you think it is worth investing in some of the more expensive impulse reverb packs when we have great packs such as these available as donationware?

  • i got my hands on some 480L iR’s a time ago, using them with the built in iR reverb [reverance] in cubase. i like convolution reverb in general cause it sound authentic and if you build custom rooms, you have like a trademark room-sound of your own. thanks for the links!

    • Ilpo Kärkkäinen

      Thanks for the comment. Creating a trademark room sound for yourself is a great idea! It’s easy to forget that reverb can be such an important piece in how we perceive things.

      • absolutly – i have some presets that i use again and again cause the work with certain sounds and just need little tweaks to fit them. its also a workflow thing, having pre-build reverbs that you can play with.

        • Ilpo Kärkkäinen

          Yup all about finding those gems that become a standard part of your workflow!

  • Thank you very much Ilpo. I’m now looking forward to playing around with some convolution reverb as it’s something I’ve shied away from before!

    • Ilpo Kärkkäinen

      Great! This is what I love to hear!

      What I like to do when testing new verbs is take a relatively sparse drum pattern, and try all the different verbs on that same pattern. That helps you learn the differences in character. Minimal techno drum patterns are great tools for that.

  • Tobias

    Big thanks for this info Ilpo, ive found its given me a fresh outlook on the overall mix and fx on sounds….im still yet to sit down and hunt out my favourites but seem to be getting good results from majoirty of impulses im trying.

    • Ilpo Kärkkäinen

      My pleasure – good to hear.

  • david

    what reverb impulses do you like specifically for clean/distorted guitars and for drum bus?

    • Ilpo Kärkkäinen

      I rarely work with guitars myself but I would say the Bricasti pack is a great all-rounder that seems to blend in nicely in almost any situation. I use it a lot on drums as well.

  • david

    which ones are your favorites in the bricasti pack?

    • Ilpo Kärkkäinen

      It depends a lot on the type of music and sounds I’m working on. My normal process is to just try different ones and pick the one that sounds best with the material I’m working on.

      The Bricasti ones are pretty smooth “bread & butter” type of reverbs that really try not to stand out I think. So I don’t really have a favorite one, I just pick what sounds good for each occasion. If I need something flashy then I usually go for something else like the Lexicon ones.

  • It really depends on the source file. There’s no right or wrong in mixing as long as it sounds good 🙂

  • Rolfie

    Thank you for great information and links! I am still quite a beginner using Logic, and this might absolutely also have saved some quite unnecessary investments at this stage.
    (also totally new in this forum, found this great site this afternoon:-)
    Saw that e.g. Bricasti uses separate left and right impulse files. Have not found out way to pick more than on file at a time to use in Space Developer (that I also just recently started to dig into that one). but am I right in that it are actually 2 identical stereo files in practice? (Why using one of them works as good in this case)?

    Also takes a chance to ask around about “positioning on stage impulses” (similar to Altiverb). Was a little impressed by the promotion video describing how several positions were recorded. I could guess some extra cpu might be required to run several reverbs in parallel to achieve these. If I have got it right.
    Anyone seen something similar – “impulse file recordings” possible to download??
    (maybe it is already included in some..:-/)

    Thank you in advance!

    Kind Regards Rolf

      • Liran Ziv

        really? i must be blind cant find how to download them could be the area country or whatever ? thanks man but how do i download them ?

          • I have just tried all the links and it looks like the Eventide, TC and Lexicon aren’t working properly anymore. I’m sorry – the post is over 3 years old. However the Bricasti one still works. Just click the link and download the impulses.

          • Liran Ziv

            thank you very much for your attention, ive already downloaded the bricasty and i really would like to hear the eventide and the 480l , is there any other way to get them ? maybe a web transfer link ? i will be sooooooo thankfullll !!!! thanks anyway for your reply

  • Liran Ziv

    although im not a cat the curiosity is killing me. i really like to try those ir’s but it is asking me to fill paypall fields before the downloading starts . can anyone suggest something ? maybe a link to dropbox if it is not too over-the-line-request
