| 描述： | Pseudo random noise produced by progressively adding and overlaying pure tones. Generated by choosing a random frequency in the audible range (uniform sampling) and then adding 80 samples (about 1.8ms) of that frequency, then repeating the process for a different frequency. 0:00 to 0:02 as described above, only a single tone at any time.0:02 to 0:07 similar, but there are 5 tones overlaid; again each is random.0:07 to 0:12 same but with 10 tones0:12 to 0:17 15 tones0:17 to 0:22 20 tones This sound, at least at the end, should be fairly close to white noise though it sounds like there's still some residual tonal structure present. As with the previous example, the sound consists solely of a relatively small number of pure tones, but the presence of randomness does the hard work as far as removing the tonal structure of the sound to get us close to a state of noise. It's this balance of pure tones versus randomness that I was originally interested in investigating. |
