I was reading an article about recording a guitar and the guy was recommending doubling the track by actually recording it twice. I realize that this thickens up the sound which is good but is playing it a second time any different then just duplicating the recorded tracks in my DAW? It still beefs up the sound but I'm not forced to play it perfectly 2 times. ThoughtS?
Actually recording it twice produces a "chorus" effect. Think of the vocals in your average Queen song; Freddie Mercury would often sing the same thing multiple times with the same approximate timing and pitch, but due to natural imperfections it sounds almost as if he's singing with someone else. Simply doubling the same track won't do this, even if you offset it a little; you're trying to introduce imperfection, and a perfect copy won't do that.
This is different from recording the second part with a different guitar, of course.
There are many reasons to double guitars in a recording, but the main one, in my opinion is because you want to pan the two tracks on the side during mix. Guitars have frequencies that typically compete with the voice tracks, which you want to keep in the middle.
Now, simply doubling a track won't cut it, because there is no way you can move the two tracks on the left and the right (it would always appear in the center of the spectrum).
There are alternatives to dubbing guitars - none of them give the same effect in my opinion but you might want to try them.
- use a chorus/phaser/flanger/pitch shifter: this gives you another track which you can pan.
- use a short delay between two copies: this gives though has an aftereffect due to phases known as the "comb effect" which is probably not very desirable.
If instead you opt for dubbing them you have the following options:
- Use the same setup and play them as close as possible. This is the classic "wall of sound" choice (actually it's not that uncommon to use four guitars).
- Use different setups and play them as close as possible. This can sound very nice but it's tricky to get balanced right in the mix. A classic combo is using a strat and a les paul.
- Use the same setup but play different parts. For example, on strumming parts, it's great if the strumming rhythms are different.
- Use different setups and different parts: classically, a strumming six string and a strumming twelve strings.
If you literally duplicate it in your DAW, then you have a sample-for-sample copy of the original track. Unless you change one of the recordings somehow, it won't make the resultant sound beefier so much as it will make it twice the volume.
Re-recording it causes a different-enough sound that it allows things to be "thicker" because even though it is one part, it sounds like there are two instruments playing it. Because there are.
If you don't want to play it a second time for whatever reason (and there can be many reasons for this) you might consider messing with the other track a bit. Delay it slightly, vary the pitch in tiny increments over time, things like that. Alternately, you can omit the second track entirely, and just put a delay or chorus effect on the original track. A chorus is designed to produce an effect very similar to what you described.
A couple of things with doubling up recording a guitar track; you can for the first recording, dial one tone into the amp and for the second recording dial in a different tone and play the same track again, effectively mimicking two guitar tones(guitarists) playing together; you could then double each of these up and push one of each to each speaker.
As Matthew pointed out; using a different guitar can add to the above effect
Other than this I cant see a good enough reason; when working on solo material; though I know of people who need to double or triple up their guitar recordings to get the tone they want.
I did see an interesting video on Youtube were a guy played a track, doubled it up and the quantized one of the tracks to create the chorus effect Matthew is talking about without actually recording the rack twice. I have never applied it; but it looked useful enough (sorry cant find it, it was a while ago).
Simple double tracking is something that I've been doing this for years - playing two identical tracks of the same take doesn't just make it louder -it seems to make it thicker- I know that double tracking is supposed to use twin takes or delays but I keep it simple and it works for me-I then seperate the pan positions slightly to increase the thickening effect- as always use your ears - it's easy with digital recording :give it a go yourself!
Problems when simply copy the same track to another track. Frequencies are the same for both tracks and this can lead to sound loss as the frequencies compete for space in the mix and can lead to sound drop out. Quantising one of the identical tracks to offset one fron the other by microseconds can help to prevent this but not always. Adding a new track maximises the effect of building depth and enhancing stereo as the individual tracks can be sent to left and right channels and if necessary overlap in the centre somewhere without leading to sound drop out or distortion.
