There’s been lots of buzz and discussion about aliasing online recently, and lots of confusion, too.
Is it a flaw in the whole idea of digital audio ? Does it explain why analogue modelling plugins can never sound exactly like the real thing ? Or is it just inaudible mathematical theorising ?
In this episode we try to answer all these questions, plus Ian attempts to give an easy visual explanation of what aliasing is and how it relates to audio, with – er… questionable results.
Along the way discuss:
- What wagon wheels have to do with audio sampling
- And vinyl turntables
- And digital audio
- How (and why) to avoid aliasing
- Why high sample rates may help and
- Why all this is important when using plugins
