"In signal processing, white noise is a random signal having equal intensity at different frequencies, giving it a constant power spectral density." Ref. https://en.wikipedia.org/wiki/White_noise We can see why your generated "white noise" sounds different from Audacity's white ...

Re: Disable automatic low pass filter when resampling

Right. It won't. The Nyquist limit is half the sample rate. Aliasing is "false" lower frequencies that are created if you don't filter before downsampling. Exactly so. Example, If you generate a sine tone at 5 kHz and resample to 8 kHz, the Nyquist frequency is 4 kHz. "Proper" r...
