Can you reverse the phase of a wave in Cool Edit Pro? I have never had to do it, but was just wondering. Also I was posting another topic for Chris. :)

Nevermind: Effects --> Filters --> Graphic Phase Shifter

So with this to reverse the phase you would flip it 180 degrees right?
 
I was trying to figure it out also, but after 'flipping' that stuff, i hear it still being out of phase.
So my solution always is to stay away from the phase and just zoom in and move the block a very small piece. you won't (really) hear it and the problem is solved.
 
You know...I'm gonna' admit something here for the first time. I have no idea what a "phase" problem is. I hear people talking about these things, and maybe I have them, but whenever I see the words "phase" or "polarity" associated with recording, I leave the room quickly, and very very ashamed...hoping nobody will figure out what a complete fraud I am.

But hats off to Beez for the additional thread. Yeah, this is starting to look like a real forum again.

:D
:D

BTW

Yes, that last post is a cry for somebody who knows about these things to just go OFF. Let us have it. Teach us. I care not that this is perhaps the "wrong" forum. I wouldn't DARE post such a lame question in a forum that got really high traffic...LOL.

Make it good, tho...b/c these 5 stars are just burning a hole in my pocket.

:D
:D
 
Ok well then it's my honour to kind of explain wat a phase problem is, as far as I can.
Very simple; sound is changing pressure of air, more pressure and less pressure (the conus of the speaker goes 'in', the conus goes 'out', same for mics).
Now let's take a snaredrum for example.
It's miced on the upperside, and on the bottom.
Drummer hits the skin, which is also a moving thing like strings, mic's, speakers, actually everything that goes up and down; changes air pressure; produces sound..
When the skin goes down, the pressure of the lower mic is increased, and of the upper is decreased.
Now when you play those two tracks back, the output will get a signal which increases and decreases at certain points together with the same sound, so they compensate each other, which sound really strange.

Hope you'll get it. There's a lot more to say about it, but this are the basics.

I will soon post an example.
 
Ok..
first of all my excuse for my bad english, it still sucks, hope you understood me.

Well I made an example with a dry guitar piece.



What you hear is;

Example 1: Guitar in normal phase.
Same guitar in opposite phase is fading in.
You hear the sound becoming much weaker.
Guitar in normal phase fades out.

Example 2: Guitar in normal phase starts.
Guitar in opposite phase start 21 ms after 1.
It sounds normal, the phases are not working
against each other.

I panned the guitars in both examples app. +17 and -17, so you can hear the difference between them in time.

So I still think the best way to solve these problems is moving one part in the mix, it's also going to sound fuller because of it...
 
Hey...I'm getting a "site is currently unavailable" error. This sounds exactly like what I was looking for. Your English is better than mine.

Please fix the site???
 
Geocities doesnt allow direct remote linking.You need to post a link to the song on your Geocities homepage.
 
I'm sorry, I can't reach geocities today, it's too busy.
Try right-click and 'save as'. This works most of the times.
 
Chris you definately need to study up on phase ;) Phase problems can occur whenever you have the same source on 2 different tracks whether it's a delayed copy track or stereo micing of a single source.

To tell if there is a phase problem listen to the tracks in mono. If the sound gets weak or tinny sounding only in mono then you have phase issues. You usually don't notice phase issues when the tracks or panned in stereo but they can crop up when you listen on boomboxes or stereos where the speakers are close enough together to create a mono type of sound.

In most DAWs you can 'Invert' the waveform to reverse the polarity or like F said you can slide one of the tracks by a few milliseconds until it sounds better.
 
Hey I found out today how to invert the phase in cep2 very easily. I was messing around with the graphic phase shifter - this is useful for inverting just certain frequencies - but just click in Edit view Effects - Invert.
Ready.. :D
