# This sketch demonstrates how to create synthesized sound with Minim
# using an AudioOutput and an Oscil. An Oscil is a UGen object,
# one of many different types included with Minim. For many more examples
# of UGens included with Minim, have a look in the Synthesis
# folder of the Minim examples.

# use the getLineOut method of the Minim object to get an AudioOutput object

# create a sine wave Oscil, set to 440 Hz, at 0.5 amplitude
@wave = Oscil.new( 440, 0.5, Waves::SINE )
# patch the Oscil to the output
