Write a method called erasePart to set all the samples in the 2nd second of "thisisatest.wav" to 0's-essentially, making the 2nd second go silent. (Hint: Re- member that getSamplingRate() tells you the number of samples in a single second in a sound.) Play and return the partially-erased sound.

Question

What will be an ideal response?

Answer 1

```
public void erasePart ( int s t a r t , int end )
{
for ( int i = s t a r t ; i < end ; i++)
{
this. etSampleValueAt ( i , 0 ) ;
}
}
public static Sound erase2ndSecThis IsATest ( )
{
Sound s = new Sound ( Fi l eChoos e r . getMediaPath ( " t h i s i s a t e s t .wav" ) ) ;
int numInSec = ( int ) s . getSampl ingRate ( ) ;
s . e r a s ePa r t ( numInSec , 2 * numInSec ) ;
s . play ( ) ;
return s ;
}
