What is a glitch effect?
A glitch effect is the deliberate use of digital errors, stuttering artifacts, and unpredictable sonic disruptions to create weird textural elements. It’s a form of controlled chaos — distorting, stretching, chopping, and resampling sounds to create something unexpected.
Glitch sounds first emerged as a happy accident from malfunctioning CD players, digital distortion, and corrupted audio files. Over time, producers started replicating these unpredictable elements with sampling, granular synthesis, and creative editing. Now, glitch is a staple in electronic subgenres like IDM, glitch-hop, and experimental music. They are also used in films to create strange sci-fi effects.
