How can aliasing from compression and saturation plugins be reduced?
Oversampling within the plugin.
80
Can analog equipment cause aliasing?
No, aliasing only occurs in digital plug-ins.
81
How do saturation plugins cause aliasing? (2)
The harmonic distortion caused by the plugin pulls up frequencies that are above the sample rate. , These frequencies are reflected back into our hearing range and become unharmonic.
82
How does oversampling prevent aliasing?
It creates more headroom for the 3rd harmonic distortion to occur, so even if a harmonic aliases, it will reflect back down above 20kHz and remain unheard.

90
How does an analog tape delay work?
