Frequently Asked Questions

It's decent for the price, exhibiting a generally smooth roll-off but lacks the subtle nuances of higher-end pink noise generators.
No, it's purely a noise generator; it doesn't produce random voltage values.
Like most digital and analogue noise generators, it’s pseudo-random, meaning it’s generated by an algorithm, but it's sufficiently unpredictable for most applications.
