whitenoise generates a soundfile which contains uniformly generated random sample values. Using the -e option, the random number generator can be seeded with the given integer. Seeding with a value of 0 will instead seed with the current time. Generating whitenoise soundfiles with the same random number seed will create identical sound samples.

Whitenoise contains all frequencies with energy evenly distributed by frequency. the output from the whitenoise program can be slightly lowpassed by holding the random samples by more than one sample. The random samples generated can be held for a specified number of samples using the -h option.

Hold 1
[hold 1 random samples]
Hold 10
[hold 10 random samples]
