If you are an embedded engineer, an audio hobbyist, or a data scientist, you have likely bumped into the three-letter acronym that rules them all: DSP (Digital Signal Processing).
Digital media processing involves the mathematical manipulation of digitized real-world signals, such as voice, video, and pressure. The workflow typically begins with an Analog-to-Digital Converter (ADC) that translates continuous signals into a binary format (1s and 0s) for computational processing.
