Forvrængningsparametre

Forvrængningsparametre, or distortion parameters, are values used to quantify and describe the non-linear behavior of systems, particularly in audio processing and signal generation. These parameters aim to capture how a signal deviates from its original form as it passes through a device or algorithm.

Common distortion parameters include Total Harmonic Distortion (THD), which measures the power of harmonics added to the original signal. Intermodulation Distortion (IMD) is another crucial parameter, assessing the sum and difference frequencies created when multiple sine waves are input. These parameters are often expressed as percentages or decibel values, with lower values generally indicating less distortion and a more accurate signal reproduction.

Other related distortion parameters might include transient distortion, which describes how a system handles sudden changes in signal amplitude, and clipping, where the signal amplitude exceeds the system's maximum capacity, leading to a flattened waveform. Understanding and measuring these parameters is vital for engineers and musicians to select appropriate equipment, design effective signal chains, and achieve desired sonic characteristics. By analyzing forvrængningsparametre, one can make informed decisions about audio fidelity and the intentional application of distortion effects.
