Say you can only record with a sample rate of 20kHz, you'll be capturing frequencies just fine until 10kHz, only you won't be able to reproduce higher frequency correctly.

It's simple physics: to capture a certain frequency correctly, you must sample its waveform at least twice per cycle. They are available with plugins compiled separately, so that you can easily remove unwanted plugins from /Library/OFX/Plugins, or as a 'multibundle' openfx-misc-20150626-nomulti-OSX10.

You may have heard of the 'Nyquist frequency' or 'Nyquist theorem'. Windows users: Make sure to install Audacity 2. Aliasing is merely an artifact that generates a particular sound as it happens, the artifacts are organized in such a way that you seem to hear this tin foil kind of sound (that's the most obvious example, although aliasing can exist at any frequency although I have reasons to believe it'll always appear gradually from the high-end of the spectrum).Р”Р„s a final note, the aliasing effect also happens when you record a sound.

In effect this creates irregularities in the flow of waves that, when played back, are not natural sounding. The more you push it, the more it's going to smudge the waveform and it'll start critically eroding the signal you're trying to focus on and listen to. In the case of BNR, it calculates a statistical image of the noise and will smudge the waveform where it finds that the original signal features a 'picture' of the statistically accurate noise. Basically, a processor adds to the original signal the statistical signal that it thinks will compliment best the component you're trying to isolate. Any plugin might generate some aliasing or artifacts in a broader sense.Р”Р„s you process a source signal, the processor reshapes the waveform using quite simple maths (in the end, all the maths electronics can do is add or divide).

The signal is passed to a 2 channel AK5371 Analog to Digital 16 bit USB converter with sampling frequencies up to 48 KHz. It is bound to be a phenomenon occurring independently from the process you are trying to apply. A closer look of the USB turntable (a near clone of the ION mentioned above) confirm this:: Pickup is a Sanyo MG-09 magnetic cartridge with a diamond stylus and frequency response 20Hz-20kHz. I will offer potential elements of answer concerning aliasing (as an artifact from over-processing a source signal).
