ein is a scratch-pad for designing digital filters and
tinkering with sound.  You write some simple C code
in a window, with facility for feedforward and feedback
loops, execute, and you can hear the result, see a 
soundview, an fft and a spectrogram of the sound.  It
is basically an interface for Kenneth Steiglitz'
ein kleiner filter compiler.   This will only be
useful for those who know what a feedback, feedforward
loop etc. are.  It is especially useful for students
learning the rudiments of digital signal processing.

I have left a tar file in princeton.edu in the
pub/music directory (compressed).  

Please alert me to any bugs, problems etc.  Have fun.
