Internal Parameters

FilterType

Type Default Value

filter_type2 LowPass

Description: FilterType determines the two pole filter type applied

to the input signal (Lowpass, Highpass, Bandpass, LowPassQ,

BandPassQ, HighPassQ, and Notch). If no filtering is desired, Filter-

Type should be set to Off. The three Q filters are amplitude adjusted

such that the filter has unity gain at the roll-off frequency, and main-

tains this gain as the quality factor is increased. The bandpass filters

have the lowpass and highpass poles at the same roll-off frequency.

NoiseColor

Type Default Value

noise_color White

Description: NoiseColor determines the type of noise applied to the

input signal.

White Noise: Noise with a flat power spectral density, the intensity

is the same at all frequencies within a given band.

Pink Noise: A random signal whose amplitude decreases as fre-

quency increases, preserving constant audio strength per frequency

increment.

Brown Noise: Noise where the spectral density is proportional to 1/

, it has more energy at lower frequencies, even more than pink

noise.
