And it is impossible to reproduce with current Audacity, as there isn't any exact volume input in Normalize (the dB input is limited to 2 decimal places, not even 16-bit precision; please implement more decimal places AND an unencoded volume input).

Request: Normalize that uses volume instead of dB.

An n-pass filter is a filter that reduces certain frequencies. A sample level filter is a filter that only checks neighboring samples by a small amount. Sample level low-pass filter: An output sample x are input samples (x-1)×0.25, (x)×0.5 and (x+1)×0.25 added together. There is a checkbox for x-1 a...

What is an analog white noise? Does it mean white noise generated by combining sines? In my opinion trying to generate white noise by generating a random sound, is like trying to generate a gray image by generating a random image. It usually looks gray in distance, but there is a chance it's a photo...

No, that is nonsense. I'd suggest that you learn about acoustics and signal processing before telling others of your uniformed opinions. This article is Wikipedia is a reasonable place to start: https://en.wikipedia.org/wiki/White_noise For a more advanced article, there is this article available f...

white noise is a discrete signal whose samples are regarded as a sequence of serially uncorrelated random variables with zero mean and finite variance https://en.wikipedia.org/wiki/White_noise To put that into layman's terms, it's a series of random sample values. For a detailed understanding, see ...

A sequence of random numbers?! That seems like an awful way to generate white noise. Suppose that by chance, this noise function generates a song. This is definitely not a uniform white noise.

I already know that. But the question is how the noise is generated, and not what properties the generated noise has.

I'm curious how noise is generated. My guess is that noise of length x seconds is generated by adding up sine waves in increments of 1÷x and random phases, then normalized to the desired volume, and that pink and brown noise is made by varying the volume of the sine waves.

Bump; this post shows the reality and what–it–should–be brilliantly: http://forum.audacityteam.org/viewtopic ... 97#p344797
