# Voss algorithm and pink noise

the voss' algorithm generated a 1/f series. What does the series mean? For example, we use three dice and the result sequence length is 8. Let's set the sequence is 8,15,6,9,14,10,9,7. Then what does this sequence mean? does it mean the sequence of frequency or something else?

The sequence produced by the Voss algorithm is a sequence of random numbers whose power spectral density decays with frequency as $1/f$. In other words, if you find the magnitude spectrum of the sequence (in other words, the magnitude of the DFT of the sequence), you'll see that it decays roughtly as $1/f$.
If all you need is $1/$ noise, there are other methods to generate it; see Pink ($1/f$) pseudo-random noise generation.
• You use the DFT. If the sequence has $N$ numbers, you get $N$ "bins". If the sequence corresponds to noise sampled at frequency $f_s$, each bin corresponds to frequency $f_s/N$. In every case, you'll get similar behavior of the PSD. This is a bit off-topic for this question -- if you need more help on the DFT, I suggest you start by reading some of the many DFT-related answers on this site. – MBaz Nov 4 '15 at 23:07
