I would like to generate pink/white/blue/purple noise and set the duration of this signal. I'm using this code:
signal = dsp.ColoredNoise('Color','pink','SamplesPerFrame', 1024);
In my understanding, the 'SamplesPerFrame' variable does not indicate the duration of the generated signal, but rather the amount of samples used to obtain the desired spectral distribution (white, pink, etc ...).
How can I generate a pink noise using 1024 samples per frame (spectral distribution) and also have 20 seconds of audio duration?
I'm using:
duration = 20; % seconds
Fs = 44100; % Sample Rate (Hz)

I was wrong. The 'SamplesPerFrame' parameter is the length of the signal. Sorry...

hello did you figure out how to set the sampling rate? its very confusing with the matlab parameters. i want to fs to be 250 hz and have 20s of desired output.
