Программирование на синтезаторе Java

Question

Я пытаюсь научиться создавать синтезатор с нуля, используя Java. Я пытался связать воедино некоторые учебные пособия и код, чтобы попытаться изучить основной рабочий продукт, но у меня нет звука. Я просто хочу иметь возможность генерировать звук, используя грех, пила и прямоугольные волны. Когда я запускаю программу, у меня нет звука. Я думаю, что мои проблемы в классе Main.java и классе SamplePlayer.java. Я получаю сообщение об ошибке в классе SamplePlayer.java, которое я опубликую в конце. Кто-нибудь знает, что я делаю неправильно или что нужно изменить, чтобы создать базовый звук?

У меня 6 классов:

• Envelope.java (настраивает генератор конвертов ADSR)

• Main.java (содержит основную функцию)

  public class Main
  {
      public static void main(String[] args) 
      {
      // Create an oscillator sample producer
      Oscillator osc = new Oscillator();
  
      // Set the frequency
      osc.setFrequency(500);
  
      // Set the waveashape
      //osc.setWaveshape(WAVESHAPE.SIN);
  
      // Create a sample player
      SamplePlayer player = new SamplePlayer();
  
      // Sets the player's sample provider
      player.setSampleProvider(osc);
  
      // Start the player
      player.startPlayer();
  
      // Delay so oscillator can be heard
      try
      {
          TimeUnit.SECONDS.sleep(4);  
      }
      catch(InterruptedException e)
      {
  
      }
  
      // Stop the player
      player.stopPlayer();
  }
  
  }
