Loudness With Filter
Description
The Loudness with filter block applies the filter to the input signal and loudness will apply to the filtered signal.
The loudness with the filter block gives access to a variety of filter algorithms. The available filter types are
- Second-Order Low Shelf
- Second-Order High Shelf
- Second-Order Parametric
- First-Order Low Shelf
- First-Order High Shelf
- Peaking
Usage
To access the filter click on the icon button and icon button image will change to reflect the selected filter type
