Record Acoustic Guitar and vocal @ the same time
Hello,
Can anybody help me in finding a way to record the vocal and acoustic guitar at the same time without bleeding both tracks into each other?
Thanks,
TWarp

we'll need more information - what soundcard are you using? what inputs are you selecting on your audio tracks?

Is the singer the same person playing the guitar? If you have two performers, put the singer in one room and the guitar player in another and use head phones so they can hear each other. If it's one person playing both parts it will be fairly difficult to record both tracks without any bleed.

Two Cardiod mics pointing away from each other will give you nice isolation.
You will never get total isolation however unless you use either a foam block or record one at a time.

You will need a pair of figure 8 polar pattern mics.
There is a null point in a figure 8 mic.
You arrange them in such a way so the guitar mic null is pointing at the voice and the vocal mic null is pointing at the guitar.
Two two types of mic capable of fig 8 polar pattern are dual diaphragm condensers and ribbon mics
Ribbon mics have a deeper null than condensers. If I am correct the null is 40db for condensers and 60db for ribbons.
You can get usable isolation this way.

I was going to say impossible, but then I reminded myself that exact terminology can be taken very seriously in this forum so I went with "fairly difficult" so that I wouldn't have to spend the next week defending "impossible". ;)

Scott, I totally get that. One small slip around here and the thread goes south.

Hey Middleman,
What do you mean by a foam block? The reason I'm asking is that I tried doing them seperately but the timing just wasn't there if you know what I mean. I would like to play and sing together. Each one plays to the other.
Thanks,
TWarp

Hey bitman, Thanks for the reply. I believe that both of my mics are 8 polar pattern. Can you elaborate a little more on the procedure? How do I know the null point?
Thanks

What I do is, I record my with headphones on and use my electric. Then I go back and record my acoustic part, with headphones on, so I can use multiple mic's on my acoustic without fear of bleed over from my vocals. It's rare you get a good take anyway on the first shot so you'll probably have to go back and redo the guitar anyway, and the vocals too so it's no big deal to do it this way.

Homemade foam pad about 3 inches thick 2x3 feet can be hung from the vocal mic stand and then rests on the guitar. It blocks the voice from the guitar. I read that Tony Visconti used one for James Taylors hourglass album. I built my own. It works, you get decent isolation unless you have a very live room. Doesn't work for Pete Townsend arm swinging types but for general strumming and picking on an acoustic, it's usable. Kind of what Bub suggests, you can just record both at the same time and don't worry about the bleed. Then come back and double both the vocal then the guitar separately using the original track for timing. Then just throw away the original. Worse that can occur is some headphone bleed.

Middleman,
Sounds like a plan. I have access to such a pad.
Thanks for the input.

Bub,
Good thinking,
I can play the guitar without the vocal but not the vocal without the guitar.
Good thought.
Thanks,
TWarp

this is a nice demonstration of the two figure of 8 mic technique which i believe bitman was referring to. although many home recordists (like me) don't have two figure of 8 mics. ...still good to know and understand. http://www.youtube.com/watch?v=0QWNXzp5P6g

my bad. I misunderstood the question.
I would use the figure 8 mic technique described above if it were me.
