Audio Toolkit - pinknoise

X = pinknoise(n)

X = pinknoise(sz)

X = pinknoise(sz1, sz2)

X = pinknoise(___, typename)

X = pinknoise(___, 'like', p)

Create pinknoise using random numbers through a series of randomly initiated SOS filters..

Note: this function uses zp2sos and sosfilt from the signal package, which will be loaded as part of calling this function.

Inputs

n - scalar value for length of the pinknoise

sz - A 2 element vector for [length, number_of_channels]

sz1, sz2 - scalar length and number of channels.

typename - datatype to create - ’double’ or ’single’.

p - matrix of data to use class type ’double’ or ’single’.

Outputs

X - pinknoise output

Examples

Create 10 second 2 channel pink noise waveform at 44.1kHz

 fs = 44.1e3;
 duration = 10;
 y = pinknoise (duration*fs, 2);
