CONCEPTS SUMMARY

Chapter Learning Objectives

The media learning goals for this chapter are:

• To blend sounds so that one fades into another.

• To create echoes.

• To change the frequency (pitch) of a sound.

• To create sounds that don't exist in nature by composing more basic sounds (sine waves).

• To choose between sound formats such as MIDI and MP3 for different purposes.

The computer science goals for this chapter are:

• To explain blending as an algorithm that crosses media boundaries.

• To build programs from multiple methods.

• To introduce class (static) methods.

• To introduce private (helper) methods.
