to get a "reverse the phase" to work, the track has to be 100% identical. If there is ANY difference it will not cancel properly and you will hear something.
To do this..... do not record it twice. Record it once and clone that track.... then flip the phase. You now stand the best chance for a total cancellation to occur. recording it twice allows for small variations to occur and it won't cancel properly.
I'm still thinking a set of noise canceling ear buds are the best, quickest, and easiest solution.
http://reviews.cnet.com/h...5-7877_7-33772066.html I was first introduced to these when I bought my Dell laptop. They came with it. At that time they were around $75 a pair.
I have bought these things in bulk from Amazon for around $15 a pair. I personally think the bass in them is superb with nice crisp highs. I have compared them to "professional" headphones at a Sam Ash pro-audio dept. I was prepared to buy up to a $300 set of cans..... after comparing them, I decided to keep the money in my pocket and continue to use the EP-630's and my other existing cans.
As far as durability, at $15 a pair...(check prices on Amazon to find the best price).. they are almost a disposable commodity. I do have a set now on my MP3 player that has been operating fine for well over a year. They get almost a daily workout.
the soft rubber cups (they provide 3 sizes...S, M, L for individual comfort levels) do a fine job in isolating the outside world's noise meaning you don't have to really crank them to hear the music. I wear them on my riding lawn mower when cutting the grass, and can listen to acoustic guitar music easily.
