Distortion, particularly in the context of audio and visual signals, refers to any alteration of the original waveform or image data. This alteration can be intentional, as in the case of musical effects, or unintentional, arising from limitations in equipment or transmission.

In audio, distortion can manifest as clipping, where the signal's amplitude exceeds the system's capacity, leading to a flattened or squared-off waveform. Overdrive and fuzz are examples of intentional audio distortion used to create a richer, more aggressive sound. Harmonic distortion introduces unwanted overtones, while intermodulation distortion creates new frequencies based on the interaction of existing ones.

Visual distortion occurs when an image's geometry is altered. This can include lens distortion, where straight lines appear curved, often seen in wide-angle photography. Digital image processing can also introduce distortion, such as pixelation or aliasing, when resizing or compressing images. Compression artifacts are a common form of visual distortion that can degrade image quality. Understanding the type and cause of distortion is crucial for diagnosing and correcting signal degradation or for achieving desired artistic effects.
