Values
| Name | Description |
|---|---|
| ltAbsolute | Applies the logarithm with base 10 and produces result in dB. |
| ltAbsoluteParam | Applies the logarithm. Uses additional parameters for log base and scaling. |
| ltRelative | Applies the logarithm with base 10, produces result in dB and positions the maximum value at zero. |
| ltRelativeParam | Applies the logarithm and positions the maximum value at zero. Uses additional parameters for log base and scaling. |
