cancelDecompose

cancelDecompose()

(Since HALion 7.0)

Description

Function to cancel the decompose function for an audio file. You specify the audio file with the AudioFile object that is returned by the AudioFile.open function. To cancel the decompose of a specific audio file, the AudioFile object of the cancelDecompose function must match the AudioFile object of the corresponding decompose function.

Available in: Controller.

Example

outputModes = { "Tonal", "Noise", "All", "Mix", }
 
defineParameter { name = "Decompose", default = false, onChanged = function() if Decompose then onDecompose() end end }
defineParameter { name = "Cancel", default = false}
defineParameter { name = "Sensitivity", default = -24, min = -96, max = 0, increment = 0.1 }
defineParameter { name = "Cutoff", default = 20000, min = 20, max = 20000, increment = 1 }
defineParameter { name = "Duration", default = 80, min = 0, max = 100, increment = 0.1 }
defineParameter { name = "TonalLevel", default = 0, min = -96, max = 12, increment = 0.1 }
defineParameter { name = "NoiseLevel", default = 0, min = -96, max = 12, increment = 0.1 }
defineParameter { name = "Start", default = 0, min = 0, max = 1000, increment = 1 }
defineParameter { name = "Length", default = 0, min = 0, max = 1000, increment = 1 }
defineParameter { name = "OutputMode", default = DecomposeOutputMode.all, strings = outputModes }
defineParameter { name = "OutputPath", default = "" }
defineParameter { name = "Subfolder", default = "" }
