Pseudo Random Noise - 18ms durations
by Speedenza
Description
Another pseudo random noise sample.
This one is generated by choosing a random frequency in the audible range (uniform sampling) and then adding 800 samples (about 18ms) of that frequency, then repeating the process for a different frequency. So at any point only a single tone is present.
The 800 samples value was originally chosen to give durations for each tone that are close to the edge of what the ear/brain should be able to discern. This may be misleading - see my later samples for more on this topic. The result is quite 'bleepy' which suggests that the ear is attempting to resolve individual tones.
This sound should have an overall power spectrum close to that of white noise (at least for long samples) - which isn't the same thing as saying that it is white noise - it's clearly not. Two sounds with similar power spectra can sound very different!
And if you don't care about theoretical niceties, it's still a nice bleepy sample.
