noise reduction and holophonic sound

I'm trying to two things. I know there are ways it can be done but with applications I don't have at the moment so I want to know if there are ways to achieve similar results with what I have before acquiring new applications. Right now I'm working on FCP 5 with Soundtrack (non-Pro version) and I just got Logic 7 express.

1) I'm trying to isolate and remove particular sounds like hums and buzzes. I know it can be done in Soundtrack Pro and Sound Forge. Here's a link to how its done on soundtrack pro: http://www.apple.com/finalcutstudio/...reduction.html

2) Manipulate sound like in the following link where it pans up and down. Someone said it was done in Logic Pro using surround sound.

I thought that was like an binaural recording.

You just place 2 microphone elements exactly where your ears are and start recording.

Playback with headphones.

It's nice effect... would it work being played thru speakers?

what kind of mics? omnidirection or shotgun? i'm gonna give that a try.

The file kind of works without headphones but you dont get the up and down effect as much.

I actually made my own binaural stereo microphone with a cheap pair of over the ear headphones from Radio Shack.

You just replace the un-solder the individual speaker element from the headphones and replace them with the microphone element which you can also buy from Radio Shack.

I think I used the PC Mount Condenser Microphone Element-- Catalog #270-090. You need two pieces at $2.59 each.

You then plug the microphone stereo jack into your stereo recorder.

[Don't ask me about Phantom power or anything like that..]

You might check this out:

The last time I used them, I wore them like headphones and started recording ambient sounds etc.

Playback of these recordings are a joy.

What a great idea! If you ever happen across some work by Leighton Pierce, who is an abstract video artist and professor at Univ. of Iowa, he has a short piece with this kind of mic setup and it's awesome!

I'm going to try that out...

You can buy binaural microphones pre-made for about sixty bucks.

I haven't had a chance...but I was thinking of taking my camcorder out into the city and wearing those binuaral microphones and feeding it directly into the stereo mic input on my PDX-10 and shooting some video.

Things like jackhammers, subway cars, firetrucks should sound fun.
