// First, get the data from a sound file in .wav format into your program
// You will have to modify the following line to point to your own file

FileInputStream fileInputStream = null;
File file = new File("C:\Users\sudharshan_03713\Desktop\audio\1A5.wav");
// Next, print the sound to find out its length in samples
System.out.println(file);
// The following two methods calls get the value of a sound sample at
// index 1000 and then set its value to half of the original.
int index = 1000;
int value = file.getSampleValueAt(index);
file.setSampleValueAt(index, value / 2);
// The following loop sets every sound sample to be twice its original value
for (int n = 0; n < file.getNumSamples(); n++) {
value = file.getSampleValueAt(n);
file.setSampleValueAt(n, value * 2);
}
// Listen to the sound
//sound1.play();
}

This exception java.lang.RuntimeException: Uncompilable source codeis seen when using an IDE which allows you to run your project/code, even if some classes are not compiled (due to errors in code). I suggest fixing your code and you have zero errors before running your project.
java.lang.RuntimeException: Uncompilable source code使用允许您运行项目/代码的 IDE 时会出现此异常，即使某些类未编译（由于代码错误）。我建议在运行项目之前修复您的代码并且您的错误为零。
Also, java.io.Filenever have the method setSampleValueAt(). This is what causes your code to never compile.
另外，java.io.File永远不要有方法setSampleValueAt()。这就是导致您的代码永远无法编译的原因。
