Backmasking, 和Flash一點關係都沒有， 我翻了一下中文網站，找不到他的中文，那就容我自己來吧–Backmasking, 逆向遮罩，我簡稱逆遮，技術上可說是〈反向錄音〉，又稱backward masking, or backwards masking。這是一種將訊息倒著錄進磁帶(tape)的方法。早期被搖滾樂團拿來放「隱藏訊息」(hidden message)，或用作音樂藝術效果的處理。為什麼我要介紹Backmasking, 因為實在太有趣了！就由下面這個最有名的例子開始好了–
Led Zeppelin- Stairway to Heaven
順著播[audio:http://www.backmaskonline.com/music/Led%20Zepplin%20-%20Stairway%20to%20Heaven%20FOR.mp3]
If there’s a bustle in your hedgerow
Don’t be alarmed now
It’s just a spring clean for the May QueenYes there are two paths you can go by
but in the long run
There’s still time to change the road you’re on
倒著播[audio:http://www.backmaskonline.com/music/Led%20Zepplin%20-%20Stairway%20to%20Heaven%20REV.mp3]
Glory glory to my sweet satan,
there was a little child born,
it makes me sad,
whose power is Satan,
he’ll give it with him 666,
there is a little toolshed where he made us suffer,
sad Satan（抱歉這裡的音樂沒有完全播到）
是的，這樣不知道是存心或是巧合的〈隱藏訊息〉，怎不讓人瘋狂？
