Re: True white noise
"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

Re: Disable automatic low pass filter when resampling
In Audacity 2-3-2 on Windows 8 that code just speeds it up. It doesn't "only" speed it up. It resamples the selected audio to 8 kHz, and returns the audio to the track. It does NOT change the Audacity track which is still set to 44.1 kHz. Because there are less samples in the returned aud...
