class acoular.signals.PNoiseGenerator

Bases: acoular.signals.SignalGenerator

Pink noise signal generator.

Simulation of pink noise is based on the Voss-McCartney algorithm. Ref.:

The idea is to iteratively add larger-wavelength noise to get 1/f characteristic.

seed = Int(0, desc="random seed value")

Seed for random number generator, defaults to 0. This parameter should be set differently for different instances to guarantee statistically independent (non-correlated) outputs

depth = Int(16, desc="octave depth")

“Octave depth” – higher values for 1/f spectrum at low frequencies, but longer calculation
