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

> Sound s = new Sound(1);
> s = s.makeSound1(15);                  // Try 10*i, too
> s.explore();

> Sound s = new Sound(1);                // Turn down the volume
> s = s.makeSound2(5);                   // Try i*i*i, too?
> s.explore();

=========================  DISCUSS: changing frequency (of my voice)

> Sound highVoice = new Sound(
     "/Users/wallingf/Desktop/the-voice-clipped-and-pitched.aiff" );
> highVoice.play();
> highVoice = highVoice.deepenTheVoiceV1();
> highVoice.play();

> highVoice = new Sound(
     "/Users/wallingf/Desktop/the-voice-clipped-and-pitched.aiff" );
> highVoice.play();
> highVoice = highVoice.deepenTheVoice();
> highVoice.play();

=========================  EXERCISE: another try at a negative

> Sound leghorn61 = new Sound( "/Users/wallingf/Desktop/fogleg61.wav" );
> leghorn61.explore();
> leghorn61.play();

> leghorn61.invertAtMidpoint();
> leghorn61.explore();
> leghorn61.play();

                           ----- no change -- why??
                           ----- ... shape of the curve is the same
                           ----- draw inspiration from image negate()

> leghorn61 = new Sound( "/Users/wallingf/Desktop/fogleg61.wav" );
> leghorn61.explore();
> leghorn61.negate();
> leghorn61.explore();

                           ----- still no change...

                           ----- but now a goofy idea...

> leghorn61 = new Sound( "/Users/wallingf/Desktop/fogleg61.wav" );
> leghorn61.explore();
> leghorn61.forcePositive();
> leghorn61.explore();

                           ----- interesting (but meaningless) sound

=========================  EXERCISE: reverse a sound

> leghorn61 = new Sound( "/Users/wallingf/Desktop/fogleg61.wav" );
> leghorn61 = leghorn61.reverse();
> leghorn61.explore();
