Well I hope you enjoyed my little audio lesson today. You should here nothing at all, pretty cool right?! Well anyways, this doesn't really work to well, because some instruments are mono recorded, and you lose A LOT of sound quality with this technique, and the biggest problem is that there is a lot of added stereo reverb and effects added to vocals today. With its sing-songy ‘1-2-3-4 can I have a little more, 5-6-7-8-9-10 I love you’ it’s the perfect song for practicing the alphabet and counting while also getting kids to say adorable things. Santa Claus Is Coming to Town (Originally Performed by Jackson 5) Karaoke Version 39. Black Gives Way To Blue (In the Style of Alice In Chains) 38. So for an example of complete inversion cancellation you can split the stereo track in Audacity then change it from left or right to mono, duplicate it, and invert one of them. (Everything I Do) I Do It For You - Bryan Adams (God Must Have Spent) A Little More Time On You - NSYNC (Hey Won't You Play) Another Somebody Done Somebody Wrong Song - B. O-Town (In the Style of All Or Nothing) 37. Now the reason this cancels the vocals and not most of the other audio is because vocals are always recorded in mono, while most other instruments are recorded in stereo, giving them minute differences that stand out when the tracks are flipped. The same thing would happen with the original image and the inverted one if you layered them with 50% opacity.

If you were to layer these two over each other and they were both identical (mono) you would hear nothing because they would cancel each other out.

If anyone's wondering how this works, what happens when you invert a track is the same if you invert an image, it becomes the exact opposite.
