Marking your Track Invisible (copyrights)

[vaesion]

I got real excited driving home today thinkin that i could mark my tracks for copy right purposes invisible by phase shift. When I got to the studio I said "this track was created by bryan tyson at deep productions" on a mono track then duplicated it to another track and flipped the other out of phase so it would disappear. I thought for sure if I flipped the whole song out of phase on 1 side suddenly my voice would appear but of course it did not:( DAMN!
Wouldnt that be the shiznit. You guys know anyway I could actually make this work.

Wha..? I felt like I read that backwards. Could you explain again please?

are u familiar with having 2 identical sounds on 2 seperate tracks and flipping one out of phase and u can no longer hear either one?
for those who are.........i wonder if this is how they make those silent subliminal tapes. they dont even have the ocean or birds in the back ground.......its dead silient putting messages in the air.
i wonder if thats the deal with having something out of phase........the volumes up.... .its playing but u dont hear it........
like to know more about this

i still think it would be awesome if you could decode your song and actually hear a voice in it that was phase canceled

it can be anything - even a photo

I understand phase cancellation but why would you want negate your samples this way? Can't you just mute them?

No, he wants to put an audio watermark on his recordings that you can't hear unless you phase reverse one of the stereo channels, in which case it would become audible (due to 'repairing' the deliberate phase cancellation inflicted on the original signal).

I haven't ever messed around with this stuff but my guess is if it would work at all it would work best when there isn't a lot of competing information. Like during the fadeout or during the hi-hat solo (which, I predict, is going to be the next big thing in modern music).

Whenever you mix two identical but opposite phased sources together, there's actually nothing there, so you can't expect to get something from nothing. In other words, when doing this, you're effectively putting nothing in the multi-track software. 1 + (-1) = 0. However, if you take one away, you'll get a 1 or a -1, but you can't "pull" a 1 or -1 from the zero after the fact.

You could always record one track of your voice (or whatever) very low so that the music effectively masks this recording. Then you can mix this with the same recording out of phase but without your voice. Your voice should then appear without music. Just make sure that everything is lined up to sample-accuracy.

There are other advanced methods of information hiding like placing this information in frequency ranges that are beyond human hearing (one example).

That would be cooler. Then all dogs would know it was your work, if noone else.
