Chapter 15. Sound Devices - SND
Computers had the ability to manage audio since the beginning because sound is a good communication media, starting from human conversation to a more sophisticated mechanism to give feedback for an action to the user, playing an alarm, or even doing voice recognition in order to input commands. Also, don't forget gaming purposes, which form a huge market!
Embedded computers follow all innovations regarding this technology like a normal computer. For some implementations, the audio quality is even better than standard PCs. In fact, some embedded devices are used as Hi-Fi sound systems.
In this chapter, we will present sound devices in embedded kits and some possible usages of these devices to show you how you can use them to implement a simple and low-cost oscilloscope.
