well, i'm bored, so here i go
first off, let me say i have spent several years in broadcasting and many more years doing PA.
lets say this is what you want:
you want to record 3 people talking. you will want to control the volume level of each microphone separately, because one of the othere people is a loudmouth and they talk real loud. the other one talks soft. SO you will need to adjust each one separately. so far so good.
You do this by using a mixer. it process, then combines the signals. as an added benefet of most mixers, you have other controls like equalizers, to shape the sound and make it sound just like you want it. this is probably what you meant by editing it. The mixer combines all the sources (you are using 3, but it could just as easily be 33) into an OUTPUT signal. This is usually a STEREO OUT.
just a primer here......mono and stereo MONO which stands for monaural (mono means ONE) is one single sourse of audio. AM radio signals are (99%) MONO signals. STEREO, on the other hand is made up of TWO signals. The left, and the right. Most of the time, there are overlapping things on the stereo signal, such as the vocal track of a song. The device used to "move things around in the stereo image" is the pan control, which you will find on your mixer probably just above the main volume slider. FM radio, CD's, MP3's are all stereo sources, in that they have a distinct left channel audio and right channel audio.
You plan on recording this conversation. You record onto a recording medium. Now, you have a computer, but you also have the DAT as a recording medium. you could also have a cassette. The point here is that you only need to record onto ONE of them. FOr instance, you would plug the MIXER into your computer.
I assume (and i cant help you with too much on this) that you know how to actually record in the computer. Heres what happens. YOu control the sound going into the STEREO INPUT of the recording program. It records 2 TRACKS. a left track, and a right track. Now, if all of the PAN controls on your mixer are set dead center, LEFT and RIGHT will have the same information on it.
If you wanted to give the listener the IMPRESSION that you are in the middel of the room, and one person is on your left, and one on the right,you do this with the pan control. YOu would set your mike's pan to the center position. Set Mike 2's pan control at about the 3:00 position, and set mike 3's pan control to the 9:00 position. this would separate the two mike and make it sound like they were setting on different sides of the room.
When we talk about tracks, we are refering to the way things are recorded. IN a production studio, we want to have control over everything, just like you do. SO, we record each individual sound/insturment/vocal onto a track. A song is composed of many many tracks. Track 1&2 may be a stereo drum track, Track 3 a bass guitar, Track 4&5 a stereo lead guitar, track 6 a rythm guitar, track 7&8 a stereo keyboard, track 9 the lead vocal, and track 10 the bakup vocal.
Your computer will only record **two tracks** at a time (remember, left and right). They make devices that will record many tracks at a time. They make devices that will even attach to your computer to record many tracks at a time. Adding the capability to record numerous tracks simultaneously, costs lots of $$$$.
Once we have all of the sounds recorded onto tracks, we feed the signal (composed of all those tracks) back out to a MIXER. We process the sound there and send the sound (as a STEREO signal) to a MIXDOWN deck. THis is what you actually listen to. either in cassette, cd, or mp3 format.
SO, with that primer here's what you really need to do. and i apologise, i am not familiar with YOUR particular equpment, but i can look it up on the net if i need to.
You need to plug the microphones into the mixer. Listen to the mixer and adjust the sound to get what you want. Feed the mixer signal into the LINE IN of your card. Using your sound recorder (wave recorder, or what ever is on your computer) you record the sound coming in.
i hope this helps a little. if needed we can explain things one step at a time.
not so hard. just go mike -> mixer -> Line IN -> wave program
