Okay, I\'ve a Zaurus 5000d, and, I\'ve noticed that if you plug in head phones, and pull them out very slowly, you\'ll hear a point where the sound starts to sound weird. I noticed it is EXACTLY like the effect I get when I run songs thru a voice removal plugin on my favorite mp3 player. So, there\'s a way to have a cheap voice removal effect on your zaurus, but could someone explain why this works?
