2.1.17. IIR contour type
The IIR contour type combo-box allows you to change the LUFS loudness type’s IIR filter contour. The following contours are supported:
- K-weighting
- ECMA-418
- ITU-R 468
- A-weighting
- C-weighting
Contours other than K-weighting no longer conform to the LUFS standard, but are provided for flavor and perceptual precision.
