+The Vamp plugins can be used to determine other metrics related to the sound and sonic perception of an audio signal. Here are the most important parameters in alphabetical order:
-  * **Harmonic Ratio**: Proportional amount of harmonic components in a signal.
+  * **Harmonic Ratio**: Proportional amount of harmonic components within a signal.
   * **Signal to Noise Ratio (SNR)**: Ratio of signal to (background) noise.

   * **Spectral Crest**: Ratio of the maximum value of a spectral distribution to the arithmetic mean; indicator of the degree of tonality of a signal.
-  * **Spectral Entropy**: Measure of the uniformity and redundancy of a signal. White noise has high uniformity and therefore a high entropy value.
+  * **Spectral Entropy**: Measure for the degree of order and redundancy of a signal. White noise has low degree of order and therefore a high entropy value.
-  * **Spectral Flatness**: Another measure of uniformity (cf. Spectral Entropy).
+  * **Spectral Flatness**: Another measure for the uniformity (cf. Spectral Entropy).
-  * **Spectral Roll-Off Point**: The //Roll-Off-Point// is that frequency below which 85% of the energy of a signal lies.
+  * **Spectral Roll-Off Point**: 85% of the energy of a signal is located below its //Roll-Off-Point// frequency.
-  * **Spectral Skewness**: Measure of the symmetry of a spectrum about the mean (median); a high value implies a tendency (//skewness//) to high frequency components, a low value implies a tendency to low frequency components.
+  * **Spectral Skewness**: Measure for the symmetry of a spectrum above the mean (median); a high value implies a tendency (//skewness//) to high frequency components, a low value implies a tendency to low frequency components.
-  * **Spectral Slope**: A measure of energy decay in the high frequency range; provides clues to the color of noise or the dominance of (high) partials in the spectrum.
+  * **Spectral Slope**: A measure for energy decay in the high frequency range; provides clues to the color of noise or the dominance of (high) partials in the spectrum.
-  * **Spectral Spread**: Measure of the degree of spread of a spectrum around the [[en:tutorium_sound#spectral_centroid|spectral centroid]]; used to distinguish between periodic signals and noise.
+  * **Spectral Spread**: Measure for the degree of spread of a spectrum around the [[en:tutorium_sound#spectral_centroid|spectral centroid]]; used to distinguish between periodic signals and noise.
   * **Zero Crossing Rate**: Rate of zero crossings per time; a high rate indicates a noisy signal or noise.
