Audio feedback occurs when a sound loop is created between an audio input and output, often resulting in a loud, high-pitched noise. This phenomenon is commonly experienced in live sound settings, where a microphone picks up sound from speakers, amplifying it repeatedly. It can be both a nuisance and a creative tool in music production. In music and sound design, audio feedback can be intentionally used to create unique sound textures and effects. Artists and producers often manipulate feedback to enhance their compositions, making it a valuable technique in genres like rock and electronic music. Understanding and controlling audio feedback is essential for sound engineers.
