Basics of Embedded Audio Processing Audio Signals In order to create an analog signal that represents a sound wave, we must use a transducer to convert the mechanical pressure energy into electrical energy. A more common name for this audio source transducer is a microphone. All transducers can be described with a sensitivity (or transduction) curve.

Audio functionality plays a critical role in embedded media processing. While audio takes less processing power in general than video processing, it should be considered equally important. In this chapter, we will begin with a discussion of sound and audio signals, and then explore how data is presented to the processor from a variety of audio converters.
