Digital Signal Processing (DSP) involves the manipulation of signals to improve or modify their characteristics, enabling efficient data transmission, storage, and analysis. It is fundamental in various applications like audio and speech processing, telecommunications, and control systems, leveraging algorithms to perform operations such as filtering, compression, and feature extraction.

Manipulation involves influencing or controlling someone or something to achieve a desired outcome, often without the target's full awareness or consent. It can be employed in various contexts, from interpersonal relationships to media and politics, and can be either benign or malicious depending on intent and impact.
