WebWhat is Spectral Distortion? Definition of Spectral Distortion: A measure of mismatch between two signals based on their spectral properties. The log-spectral distance (LSD), also referred to as log-spectral distortion or root mean square log-spectral distance, is a distance measure between two spectra. The log-spectral distance between spectra $${\displaystyle P\left(\omega \right)}$$ and $${\displaystyle {\hat {P}}\left(\omega \right)}$$ is … See more When measuring the distortion between signals, the scale or temporality/spatiality of the signals can have different levels of significance to the distortion measures. To incorporate the proper level of significance, the … See more • Itakura–Saito distance See more As LSD is in the form of p-norm, it can be represented with different p-numbers and log scales.
