I am developing Synth using wavetable osc.
But there is a problem in implementing better sound.
In wavetable osc., band-limited seems to be implemented using several wavetables.
However, in the case of Serum, the wavetable that you create or import is also band-limited, so Serum seems to use a different method.
I wonder if you can band-limit wavetable like Serum or similar.
English is a bit awkward.
You’re going to want to read up on BLIT and BLEP algorithms. BLEP may be patented, I’m not sure. This page has some articles you can look at.
