FAQ
Q: What is an impulse response?
A: An impulse response (IR) is basically an audio capture of an environment. It can be overlayed on top of other audio, to shape it. Normally, this technology is used to capture places like church halls or rooms to be used as a reverb effect, but in this case of cabinet IRs, it is used to capture the sound of a cabinet through a microphone. Using an IR loading plugin or similar tool to overlay these IRs on top of your guitar signal will make it sound like you are playing through the cabinet and microphone.
Q: How do I use an impulse response?
A: Use an IR loading plugin (my personal recomendation is the free Cab-Lab 4 plugin from Fractal Audio), or an amp modler that uses IRs such as the Axe FX or Line 6 Heilix.
Q: What sample rate were your IRs recorded at?
A: 48khz. If, for some reason you need a different sample rate, please send me an email.
Q: How long are you IRs?
A: Three whole seconds in length. This makes them more than long enough for trimming down to whatever format you will be using them in (for example, StandardRes vs UltraRes).
Q: If your IRs are three seconds long, does this mean I have to manually trim them down if my plugin or equipment uses shorter IRs?
A: Generally, no. I have never seen an IR plugin or amp modeller that doesn’t simply auto-trim IRs to the appropriate length when using them. If you run into a situation where this is not the case, please send me an email. I'd love to know about it.
Q: Which speaker was captured on each of the cabinets?
A: For Cab Pack: Driger, the top-left speaker was chosen on both the 4x10 and the 2x12.
Q: What equipment and software was used to record your IRs?
A: Cab Pack: Driger was recorded using a Gallien Krueger 2001RB as the power amp. The Mic/DI method was used to eliminate the possibility of any power amp colouration. A Countryman Type 10 DI was used between the power amp and cab to capture speaker-level signals from both the woofer and the tweeter. Both DI signals and the mic were recorded through Rupert Neve Designs mic preamps. Protools was used to capture everything, and Voxengo Deconvolver was used to render the IRs.
Q: Do you used any EQ on your IRs before rendering them?
A: No, all you get is the sound of the cab and mic. You may EQ them to your liking.
