See Image:White noise.ogg for details on generation and conversion. First generate 10 seconds of Gaussian white noise sampled at 48 kHz: white=randn(48000*10+1,1);
Then differentiate it and normalize it to [-1.0, 1.0), so it can be written to a .wav file: purple=diff(white);
purple=purple/(max(abs(purple)));
wavwrite(purple,48000,16,'purple.wav');
