How can i fix acoustic bleeding? (song inside for example)

Yes , there is a ratio of the sound you want to record (direct) and the other sounds you don't neccesarily want , but controlling that is usually a function of mic choice and placement.
As others have so charmingly pointed out , gain is gain.

Some condensors are like FBI spying on the mafia , picking up stuff from a mile away!
other mics are better at off-axis rejection or have a better pattern for avoiding Bleed (hyper-cadioid) .
Of course , there are a slew of other variables but there is a reason why allot of guitars a basses are recorded D.I. and re-amped later on. There are lots of cats in studios hating the headphone cups chaffing there ears too!! Bleed is one of those pesky thing you gotta deal with!! Thats why dude precceding said sometimes it's eaisier to just work with it sometimes.

:D

Im confused as to how I managed to reduce the noise to a negligable amount by turning the pre gain down though. And I did listen back to it at high volumes to check that there was no noise.
It definetly worked, no doubt in my mind, but I dont know the technical stuff behind why it happened.
Any ideas?

If lowering gain allowed you to get closer to the source, then the source vs background ratio improved. The only other vairiable I can think of would be electrical noise which may have been less than optimum to begin with.

Im sure the singer was at the same distance from the mic, and it was only room noise, no other noise.
Its a head scratcher!

Think of the pre-amp as a thing that sucks sound from the mic into your recorder. The more pre amp gain the more volume it sucks. So when the source stays the same, and you bring down the pre-amp gain, then you get less noise in your recordings.

Eck ... I think I see exactly where you're coming from on this.

Think of your posts as being sort of a vacuum.

They suck intelligence out of people's brains. And the more peeple read, the more intelijint thought and reason getssucked out until their isn't anything leaft anymore.

Yeha I totally see what you mean.
You are a genius when it comes to being a bit of a ChessCo*k

I learn from people in this forum, articles, and most importantly, from my own experiences.
What works for me works, so I use that. If its not PC or doesnt make sense then obviously there is some other factor that no one has targeted. I am no recording expert by any means, I am a mixing and mastering engineer.Id love to learn to record properly and Ill stick at it till I do.

A mic is going to pick up whatever it picks up. The only decrease in noise I can see from turning down the preamp gain is the noise from the preamp itself.

I used to think the same thing though along time ago, that by turning down the preamp gain the mic becomes less "sensitive" to little noises and whatnot but I don't think that's how it works. :p

One distinct possibility is that you simply have a noisy preamp.

A second is that you have a bit of a mic/preamp mismatch. If you are running a relatively high impedance mic into a relatively low impedance preamp, that can both decrease apparent voltage, causing you to have to pump the gain more than you should (and increasing the preamp noise level), and also cause the pre to accentuate the high frequencies a bit, causing a bump in noise.

Check you mic model and it's optput impedance spec. Then check that against the input impedance spec on your preamp. If the preamp is less than, say, 5x the impedance of the micorphone, this coul dbe contributing to your problem.

Cheers Glen.
I'm using an NT2 into an ART tube pre amp so I'm sure they are fine together but Ill check.

... So maybe this is a good time to ask :rolleyes: Avalonpess, since this is your thread and all, how's it comming? :D
 
I'd try messing with mic angle to reduce it. You're never going to get rid of it.
Messing with mic angle could make things worse if you're rooms not either dead or good.

Getting the mic's as close to their source as possible is likely your best bet if you must record both at once .

Recording them seperatly is a better bet.

how about freestanding isolation baffles?

dont the big studios use those?
 
I believe it's the same person playing the guitar & singing.
