Tutorial: Building a Simple Effect Unit with a Generic View

This tutorial chapter leads you through the complete design and development of an effect unit with a generic view. As you work through this tutorial, you take a big step in learning how to develop your own audio units.

The format of this chapter lets you complete it successfully without having read any of the preceding material. However, to understand what you’re doing, you need to understand the information in “Audio Unit Development Fundamentals” and “The Audio Unit.”

In particular, to gain the most from this chapter, you should understand:

• Properties, parameters, and factory presets

• Audio unit types, subtypes, manufacturer IDs, and version numbers

• Audio unit life cycle including instantiation, initialization, and rendering

• The role of the Core Audio SDK in audio unit development

• The role of the AU Lab application and the auval tool in audio unit development
