Hi. I’m wondering if there is a way of creating aliasing artifacts per sample with out simulating. As we understand the Nyquist frequency is the highest frequency in a digital system that can be accurately represented, and it is equal to half the sampling rate. How would we go about accurately reducing the sample rate per sample to produce aliasing as an effect.
@liminalspace - are you talking about something lower-level than say using the :bitcrusher FX? (It has a sample_rate: opt that you can play with. Or are you thinking something different?)
As you say/know aliases arise with undersampling. If you reduce the sampling rate by only using only every second sample or every third sample of the collection you will arrive at a condition of undersampling. This may cause artefacts as you wish.
Or am I wrong?
