#get_nbr_samples(iInputData) ⇒ Object

Get the number of samples that will be written. This is called before execute, as it is needed to write the output file. It is possible to give a majoration: it will be padded with silence.

Parameters

  • iInputData (WSK::Model::InputData): The input data

Return

  • Integer: The number of samples to be written
