We start with the sound and in the second chapter we explain everything about level, dB etc. without much mathematical effort. With animations and films about the FREE tool AUDACITY we try to present the basics more clearly. Along the way you will learn how to use the AUDACITY tool. Chapter 2 deals with sound in the time domain and chapter 3 with sound in the frequency domain. In chapter 4 we show the human perception, that is what we actually hear.
And what we really hear is shown in the last chapter with psychoacoustics.

Most smartphones have the ANDROID OS
and it is programmed with the programming language JAVA.

In this eBook (102 pages), we show you in the first chapter, how to install the necessary and FREE tools (Eclipse SDK, ADT, JAVA). In the second chapter we start the first project. In movies you learn the first steps with the tool ECLIPSE and we will simulate the first example on the emulator. Finally, you will learn the acceleration sensor from the smartphone to read and display the XYZ values ​​on the screen.

To create more apps, you need more than just an activity and to communicate, you need the intents.
We show that in the last two examples.
