What is Distortion?

Distortion is an audio effect that changes the original sound by altering the shape of the audio signal. This usually happens when the signal is amplified beyond its normal limits, causing the waveform to clip or become compressed. The result is a rougher, more aggressive tone that adds harmonic content to the sound.

Distortion is commonly associated with electric guitars, where amplifiers or effects pedals are used to intentionally overdrive the signal. This creates the powerful, gritty sound heard in many rock and metal recordings. The effect works by boosting the signal until it clips, which introduces additional harmonics and changes the overall character of the sound.

In modern music production, distortion is also used creatively on vocals, drums, bass, and synthesizers. Producers may apply different levels of distortion to add energy, intensity, or texture to a track. While heavy distortion creates a bold and aggressive sound, lighter distortion can add subtle warmth and presence to a recording.
