Learning Unreal Engine Game Development

By: Joanna Lee

Overview of this book

Unreal Engine 4 is a powerful game development engine that provides rich functionalities to create 2D and 3D games across multiple platforms. Many people know what a game is and they play games every day, but how many of them know how to create a game? Unreal Engine technology powers hundreds of games, and thousands of individuals have built careers and companies around skills developed using this engine. Learning Unreal Engine 4 Game Development starts with small, simple game ideas and playable projects that you can actually finish. The book first teaches you the basics of using Unreal Engine to create a simple game level. Then, you'll learn how to add details such as actors, animation, effects, and so on to the game. The complexity will increase over the chapters and the examples chosen will help you learn a wide variety of game development techniques. This book aims to equip you with the confidence and skills to design and build your own games using Unreal Engine 4. By the end of this book, you'll have learnt about the entire Unreal suite and know how to successfully create fun, simple games.

Getting audio into Unreal


How do we get the audio files into Unreal? What do you need to take note of?

The audio format

Unreal supports the importing of sounds only in the .wav format. The .wav format is a widely used format that can store raw uncompressed sound data.

The sampling rate

The sampling rate is recommended at 44100 Hz or 22050 Hz. As mentioned earlier, the sampling rate determines how often the analog wave is recorded. The higher the frequency (measured in Hertz or Hz), the more data points of the analog wave that are collected, which aids in a better reconstruction of the wave.

Bit depth

The bit depth is set as 16. It determines the granularity at which the amplitude of the audio wave can be recorded, which is also known as the resolution of the sound. For a bit depth of 16, you can get up to 65,536 integer values (216). The reason why we are concerned with the bit depth is because during the sampling process of the analog waves, the actual value of the amplitude of the wave is approximated...
