This is a vocabulary for parameters that are common in audio processing software. A parameter is purely a metadata concept, unrelated to any particular code mechanism. Parameters are used to assign meaning to controls (for example, using lv2:designation for ports) so they can be used more intelligently or presented to the user more efficiently.
The ratio between processed and bypass components in output signal. The dry and wet percentages can be calculated from the following equations: :::c dry = (wetDryRatio.maximum - wetDryRatio.value) / wetDryRatio.maximum wet = wetDryRatio.value / wetDryRatio.maximum Typically, maximum value of 1 or 100 and minimum value of 0 should be used.
