Write a method that will blend 3 sounds. Start with one sound for 20,000 samples then blend the first and second sound for 20,000 samples, then the second and third sound for 20,000 samples and then the third sound for 20,000 samples.

Question

What will be an ideal response?

Answer 1

```
/**
* Method to o v e r l a p or b l end 3 sounds . S t a r t
