def execute(iInputData, oOutputData)
  lRawSample = iInputData.Header.getEncodedString([@Value]*iInputData.Header.NbrChannels)
  # Write complete buffers
  lNbrCompleteBuffers = @NbrSamples/MAX_BUFFER_SAMPLES
  if (lNbrCompleteBuffers > 0)
    lCompleteRawBuffer = lRawSample*MAX_BUFFER_SAMPLES
    lNbrCompleteBuffers.times do |iIdx|
      oOutputData.pushRawBuffer(lCompleteRawBuffer)
    end
  end
  # Write last buffer
  lLastBufferSize = @NbrSamples % MAX_BUFFER_SAMPLES
  if (lLastBufferSize > 0)
    oOutputData.pushRawBuffer(lRawSample*lLastBufferSize)
  end

  return nil
end

#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
