Default Recording?

I'm sure someone here can point me in the right direction.

So there are a few ideas kicking around in my head for doing sound art (I know, I know, it usually sucks bad, but most people think audiophile qualities don't matter in it, but they do!). One of them involves the fact that I want to record pillow talk as nearfield, dynamic, and real as possible. I'm not sure what kind of recording device I need for this that will be extremely high quality; hearing the amount of moisture in the mouth. If I have to it can be faked between talented actors or something, but what I really want is it to be real.

Thanks for any help!

I would suggest using the smallest omni electret mic I could find. and close micing the person's mouth.

I don't know what I should plug the mic into. The only thing I do know is I will be using a power filter to keep the sound half decent post-mastering, if it isn't battery operated. It needs to specifically capture the very low tonal qualities that you can feel resonating from someone in close proximity. To the point I may greatly increase those during mastering if I don't feel they are as high as they would have been if you where in the experience. I guess rather I have to make sure I get them, is what I am saying.

One of those tiny little Mylar diaphragm omni electret mics is about the widest freq response you are likely to get without spending mega-bucks. You can buy the naked capsules for super cheap, like only a few dollars and hook them up yourself with a 9V battery a resister and a capacitor.

I used to use them all the time when I was doing recording.

James.

Like this? Goldline TEF04P Phantom Powered Omnidirectional Electret Condenser Microphone | Spectrum Audio

I have zero recording equipment so I have yet to figure out what to capture the recording on. Like the microphone has to plug into something. I imagine a portable unit could be advantageous to this?

Close mike will get you far too much extraneous noise- slight motions against the pillow case will be thunderous. Use a hypercardioid or shotgun mike a meter away pointed at the center of the "action."

No. Like this:

10 X 6mm Mini Capsule Electret Condenser Microphones

FEL Connectors and Components

An Omni mic actually has much better rejection of extemporaneous noise like wind because the diaphragm is stretched over an almost sealed rear chamber. this controls it well, unlike a cardiod, that is totally open to the air on both sides of the diaphragm that flaps in the slightest breeze like a sail.

You might try a PZM or pressure zone mic. It is an omni electret mounted on a flat plane with a tiny gap.

I'd try a large diaphragm condenser mic and suspend it about 5-10 inches above.
Good ones are switchable between cardioid, omni, figure-of-eight etc. I'd start with omni.
Something like this should do:
sE Electronics sE4400a Dual Capsule Multi Purpose Condenser Microphone

You will need a mic pre capable of supplying 48V phantom power.
Some A-D convertors have those built in.

It might be a good idea to ask this question on a forum like gearslutz.com.

A large diaphragm is exactly what you don't want! Everything about it will work against your goal. That mic actually has multiple elements that work in various phase arrangements to create the different patterns. It is not an almost sealed chamber with a tiny diaphragm, like I posted above.

Like I said, you can get omni capsules for like $1 each. They are used in all kinds of electronics like phones and pocket recorders. They are super cheap, but they also happen to be very good mics. The only problem they present is a bit of hiss from the FET transistor in the electronics that converts the changing capacitance into an audio signal.

All you need is a 9V battery, a resister, a tantalum capacitor, some wire and a phone plug!

James.

I would say the same thing about omni. Back in my pornstar days, the sound guy would always use... oh wait, I wasn't supposed to talk about that.
