cIntensity

Description

This component computes simplified frame intensity (narrow band approximation). IMPORTANT: It expects UNwindowed raw PCM frames as input!! A Hamming window is internally applied and the resulting signal is squared bevore applying loudness compression, etc.

Type hierarchy

cDataProcessor → cVectorProcessor → cIntensity

Fields

• nameAppend (string) [default: None]

  A string suffix to append to the input field names (default: empty)

• intensity (numeric) [default: 1.0]

  1 = enable the output of intensity I (mean of squared input values multiplied by a Hamming window)

• loudness (numeric) [default: 0.0]

  1 = enable the output of loudness L : L = (I/I0)^0.3 ; I0 = 0.000001 (for sample values normalised to the range -1..1)
