About the Book

Game Audio and Music: A Complete Guide to Creation, Design, and Integration is a practical guide to creating, designing, and integrating music, sound effects, ambience, and dialogue into video games using Unity and FMOD.

Through theoretical explanations and practical examples, the book covers everything from the fundamentals of sound design and music composition for video games to the implementation of interactive audio systems and dynamic music.

Is this the right book for me?

Yes. Its practical approach makes it particularly suitable for students, composers, musicians, sound designers, and developers who want to understand how to work with audio in video games and take their knowledge into a real-world implementation.

Rather than simply explaining concepts, the book takes a hands-on approach: you will learn how to identify real-world problems, develop solutions, design them, implement them, and integrate them into a complete video game project.

The book also includes The Wandering Terror, a complete video game developed specifically as a practical companion to the book. You can download and explore the game yourself, giving you the opportunity to see how the concepts and techniques discussed throughout the book are applied in a real project.
