=========================  SET UP: prepare for media files

> FileChooser.setMediaPath( "/Users/wallingf/home/teaching/cs1-media/intro-prog-java/mediaSources/" )

=========================  QUICK EXERCISE: guess the sound

> Sound s = new Sound( 0 );
> s = s.makeSound( 2 );             // tried twice, for two different tests
> s.explore();

> Sound s = Sound.makeSound( 2 );   // with makeSound as a CLASS METHOD
> s.explore();

                                   -----   Why not make reverse() a class method ?

=========================  IDEA: adding two sounds

> s = new Sound( FileChooser.getMediaPath( "and.wav" ) );
> s.explore();
> t = new Sound( FileChooser.getMediaPath( "great.wav" ) );
> t.explore();
> s.add( t );
> s.explore();


> s = new Sound( FileChooser.getMediaPath( "ew/fogleg20.wav" ) );
> s.explore();
> t = s.reverse();
> t.explore();
> s.add( t );
> s.explore();

                                   -----   This doesn't do much for us
                                   -----   just adding arbitrary sounds,
                                   -----   but it gives us the raw material
                                   -----   for creating sound effects.

=========================  IDEA: blending two sounds

> String filename = FileChooser.getMediaPath( "sec3silence.wav");
> Sound target = new Sound( filename );
> target.explore();
> Sound s = new Sound( FileChooser.getMediaPath("aah.wav") );
> Sound t = new Sound( FileChooser.getMediaPath("bassoon-c4.wav") );
> target.blend( s, t );
> target.explore();

                                   -----   perhaps better with two notes

> target = new Sound( filename );
> s = new Sound( FileChooser.getMediaPath("bassoon-c4.wav") );
> t = new Sound( FileChooser.getMediaPath("bassoon-g4.wav") );
> target.blend( s, t );
> target.explore();

                                   -----   which leads me to wonder...

> s = new Sound( FileChooser.getMediaPath("bassoon-c4.wav") );
> t = new Sound( FileChooser.getMediaPath("bassoon-e4.wav") );
> u = new Sound( FileChooser.getMediaPath("bassoon-g4.wav") );
> s.add( t );
> s.add( u );
> s.explore();

                                   -----   a C chord!

=========================  QUICK EXERCISE: generate a blended chord

> s.getLength()
55125
> t.getLength()
55125
> u.getLength()
55125

> 55125 * 5 / 3
91875

> Sound chord = Sound.blendedChord();
> chord.explore();

=========================  IDEA: echo, by adding after a delay

> Sound voice = new Sound( FileChooser.getMediaPath("ew/the-voice-raw.aiff") );
> Sound backVoice = voice.reverse();
> backVoice.play();

> voice.echo( 20000 );
> voice.play();

> voice = new Sound( FileChooser.getMediaPath("ew/the-voice-raw.aiff") );
> voice.echo( 1000 );
> voice.play();

> voice = new Sound( FileChooser.getMediaPath("ew/the-voice-raw.aiff") );
> voice.echo( 1000 );
> voice.play();

=========================  IDEA: changing a sound's frequency

> voice = new Sound( FileChooser.getMediaPath("ew/the-voice-clipped-and-pitched.aiff") );
> voice.changeFrequency( 22050.0 / 16000.0 );               //  OOPS!  wrong way
> voice.play();

> voice = new Sound( FileChooser.getMediaPath("ew/the-voice-clipped-and-pitched.aiff") );
> voice.changeFrequency( 16000.0 / 22050.0 );
> voice.play();

                                   -----   The frequency seems right now!
                                   -----   ... but the result sound is too short.
