[linux-audio-user] Software for Sine Wave Generation

[dmotd]

sounds like the perfect job for supercollider::
  http://supercollider.sourceforge.net/  
::which is an interpreted object orientated scripting language for 
synthesis and other signal processing. the language is based on 
smalltalk, with C-like syntax but isn't nearly as pedantic as csound.
