Today’s edition of Free Sample Shootout features a list of the best free guitar cab IRs (guitar cabinet impulse responses).
An impulse response, or an IR, is just a simple audio file containing a recording of a signal being played through a certain piece of equipment or in a certain space. Take a listen to an impulse response file and you’ll discover that it doesn’t sound like much. BUT, load it up in an IR loader and you will get a faithful sonic recreation of the very piece of equipment or the space in which the IR was recorded. The process which makes this possible is called convolution, and it basically allows you to take a snapshot of a particular frequency response and then apply it to other sounds.
Anyway, I’m not sure if me and my awesome Engrish skills have successfuly explained all of that well enough, so if it’s still not properly clear, take a read to this well-written thread on the Guitar Amp Modelling forum. And here’s another great article about convolution by EarLevel Engineering.

And if it’s all clear now, here’s the best-of list of free guitar cab IRs:
- GuitarHack Impulses part I by GuitarHack
GuitarHack Impulses part II by GuitarHack
- Recabinet Demo by Recabinet
- Free Redwirez IR Library by Red Wire
- Kalthallen Cabs by Kalthallen
- IR Library by Noisevault
- God’s Cab by SignalsAudio
- Fredman Impulses by Catharsis Studio
- Beamsonic Impulses by Nick Beamso
- Orange Cab Impulse by fearcomplexmusic
- IRs by le Châtelet
That’s it, and I think it’s more than enough! Free convolution software will be covered in an upcoming edition of bpb Freeware Studio, but for now I suggest you try Voxengo Boogex or LePou LeCab. Put these IRs to good use, subscribe to BPB and share this on Twitter, Facebook, Stumbleupon, or your favorite forums.
