Subject: Simple sound generator for Ruby (using PortAudio)

Hello. I pushed a simple sound generator package to github.
https://github.com/ryohashimoto/roscil

You can generate sounds in Ruby by following codes.

  require './roscil'
  Roscil.sin(440) # 440Hz sine wave
  Roscil.saw(220) # 220Hz sawtooth wave
  Roscil.tri(110) # 110Hz triangle wave
  Roscil.pulse(880) # 880Hz pulse wave

We tested this package on Mac OS X 10.6 and MacPorts 2.0.3.
You can install PortAudio library by

  sudo port install portaudio

If you use this package on Windows or Linux, please modify extconf.rb.
