Suppose I plug a phasor~ (non-antialiased sawtooth) into the sinx~ function to generate a waveform. Because this has no partials above the Nyquist frequency, I don't need to worry about antialiasing it, right?
But now suppose I modulate the frequency of the phasor~. The result can have partials vastly exceeding the Nyquist frequency. That is, they will alias. Is there anything I can do about that? Would, say, replacing the phasor~ with a saw~ (which is antialiased) help? If not, or if so but not completely, what's to be done?
I know I can't just plug the sinx~ into a LPF, because the aliasing will have already happened by then -- the frequencies have already been folded back into the audible range.
