LOBO,我看到你的名字总是想到“龙虾”,呵呵。
LOBO,去下载一个MSP,里面就有这个FFT的程序,很好玩。
我听过最有意思的声音作品之一就是用FFT做的,有时间来听听?
Quiet American - Calisthenic (An Exercise In Negative Space) [MP3 - 4 MB]
This is a process study. The entire piece is based on a short (~35 second?) recording I made in Laos, of some kids doing calisthenics in a school yard with traffic whizzing by. I loop a section of it and use an FFT filter to gradually add in more and more frequencies from the original recording until you can tell what it is... at which point I break the loop and let the recording play out.That's it - no layering, additional manipulation, etc... Quiet American is Aaron Ximm.
