[LAU] Text-based sound visualisation?

[Julien Claassen]

Hello Massy!
   The thing you need is FFT. I thought about it,maybe csound can offer a 
solution. I definitely has FFT-based opcodes and it has measuring 
capabilities. I'm quite sure about that. The question is, if you can really 
split the signal that way. Another - perhaps not so fine - alternative might 
be to use bandpass filters with steep slopes. Ecasound could do that. I think 
one could create a simple bash script for that.
   Warm regards
            Julien
