First experiments with sound

These notes were started from hhzl observations here.

The sound system was exported from Squeak, more information can be found in the Swiki, see [1] and [2].

The sound system isn't loaded in the Cuis base system, but it is included in it, you just need to load it with:

Feature require: 'Sound'.

Play a melody writing note names and duration

(AbstractSound noteSequenceOn: 
    PluckedSound default from: 
      #((c4 1 500) 
        (d4 1 500) 
        (e4 1 500) 
        (g4 1 500) 
        (a4 1 250)
        (a4 1 250) 
        (c5 1 500)
       ) 
) play

TODO. Play a melody with note names in Italian: Do, Re, Mi ...

Create a *.wav file

(AbstractSound noteSequenceOn: FMSound flute2 from: #(
  (e5 0.5 500) (d5 0.5 300) (c5 0.5 350)
  (d5 0.5 300) (e5 0.5 500) (e5 0.5 300)
  (e5 1.0 350) (d5 0.5 400) (d5 0.5 300)
  (d5 1.0 330) (e5 0.5 400) (g5 0.5 300)
  (g5 1.0 500)
)) storeWAVOnFileNamed: 'maryhadalittlelamb.wav'.

Play a *.wav file

(SampledSound fromWaveFileNamed: 'maryhadalittlelamb.wav') play

Exercise.1. Check that the class Sound isn't present in Cuis by default.
