Hi, I’m fairly new to dsp and have only recently come across a problem unbeknownst to me called “Anti aliasing” which causes this problem:
this is the spectrum of a saw wave played on my synth at a very high frequency. As you can see the harmonics are “bouncing back” at Nyquist’s frequency and going back down, even below the fundamental. This is obviously not ideal and was wondering a good way of going about solving it.
I have seen very little on these forums about antialiasing which surprises me quite a bit.
Thanks in advance
