Nonlinear distortion

Nonlinear distortion occurs when an electronic device, like a speaker or amplifier, changes an input signal in unexpected ways, causing the output to differ from a perfect replica. Instead of producing a clean, accurate version of the original sound or signal, the device introduces extra sounds or alters the wave shape. This often happens when the device operates beyond its ideal range or isn’t perfectly calibrated. Nonlinear distortion can make audio sounds less clear or natural, affecting sound quality, especially at high volumes or complex signals.
