Okay so discussion here was running a bit too far offtopic, so it was suggested to make a thread about recording and whatnot, here you go!
Discuss any techniques, questions and comments you have about recording your tracks here!
I'll start off by explaining some stuff about IR's.
What is/are IR('s)?
IR stands for Impulse Response. This also explains the technique to a degree.
You use software to create a file which holds the characteristics of a poweramp, cab, mic and the acoustics of a room.
This allows you to record your preamp straight, apply the impulse response and voila! Awesome tone!
There are many IR's available, free and paid, so you don't have to create them yourself
How are they made?
IR's (I'm not gonna spelll it out every **** time!) are made by playing a certain pulse tone through the poweramp and micing the cab.
This recorded sound is then used by the software, it analyses the difference between the original pulse and the recorded one, thus giving it the charactaristics of that poweramp, cab and mic, allowing you to slap those characteristics on a different track. (in this case a recording straight from the preamp).
How do I use them?
Step one is to make a track in your preferred recording software and plug the pre-amp out of your amp into your interface.
(in many cases this defeats the poweramp, allowing for silent practicing as well!)
Step two is to load a reverb plugin that uses impulses. (this technique was developed to create realistic and low-power reverb, as it requres much less processing power than calculating reverb).
There are a few: KeFIR, SIR reverb, Reaverb (in Reaper) and some others.
As a general rule I'd suggest using Reaverb if you have Reaper, KeFIR if you use any other DAW.
Step three: load the impulse file.
The files I talked about are very small wav files.
There are several sets to be found on the web, some of the most popular ones are those by GuitarHack, but there are better ones to be found.
It differs by plugin, but each has a load/add file button somewhere!
Step four: settings
This is where it gets a bit more complicated, as there are different plugins.
These are the settings for Reaper:
- Wet: 0db (double click the slider)
- Dry: all the way down
- Width: 1.00
- Pan: 0.00
- Pre-reverb: 0ms
- Max FFT: leave it
- ZL: on (zero latency)
For KeFIR:
- Mix: 100%
- Gain: down to -20db or something (it sets it too high by default, tweak it down untill your output volume isn't clipping!)
- Length: is set automagically!
Step five: Rock out!
Now you're good to go! The plugin now acts as a poweamp,cab and mic simulator.
Leaving you with nothing to do but tweak your preamp!
A little tip:
Packs of IR's mostly have an array of different ones, where the cab was miced differently or different power tubes where used.
Try the different ones to find your favorite! But also after laying down all the tracks, go back and switch it around to see which sound best in the mix!
Also it has to be said before anyone starts snorting and hissing:
IR's only give you a dynamic EQ, they do not give you any of the oh so sweet overdrive that a poweramp gives.
It is an easy way to get good results quicker, so if you're doing a fast demo, bedroom produced songs or whatever it's a great technique!
It is not a full replacement for cranking a roaring tube amp and micing the beast!
Cheers!
