https://www.analog.com/media/en/dsp-documentation/embedded-media-processing/embedded-media-processing-chapter5.pdf
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.

Chapter 5: Basics of Embedded Audio Processing ...
https://www.globalspec.com/reference/28388/203279/chapter-5-basics-of-embedded-audio-processing
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.

Audio in embedded systems. Our world is full of sounds. The wind, birds, traffic, buzz of voices, discussions, radio, music, sirens. The soundscape is an essential part of our environment, but all sounds are not natural anymore. Our technology causes noise and we are surrounded by devices designed to create artificial sound.
