FREQTWEAK
FreqTweak is a tool for FFT-based realtime audio spectral manipulation 
and display. It provides several algorithms for processing audio data in 
the frequency domain and a highly interactive GUI to manipulate the 
associated filters for each. It also provides high-resolution spectral 
displays in the form of scrolling-raster spectrograms and energy vs 
frequency plots displaying both pre- and post-processed spectra.

CERES3
Ceres3 is a cut-and-paste spectral editor with musically enhanced 
graphic control over spectral activity of a sound file.

SND
Snd is a sound editor modelled loosely after Emacs and an old, 
sorely-missed PDP-10 sound editor named Dpysnd. It can accommodate any 
number of sounds each with any number of channels, and can be customized 
and extended using either Guile or Ruby.
[Snd has some basic FFT operations that could be customized into 
user-defined spectral operations.]

and there are others....

ps...Tjeerd, I have written to several instructors at the HKU about 
doing an open source audio workshop there, all without reply. I live in 
Utrecht, just right around the corner so to speak. Why doesn't anybody @ 
HKU answer my emails, if there are students like you interested in Linux 
audio?
