[PD] Max Smoother Audio than Pd?

Well, that is only if all the partials remain under the Nyquist 
frequency. The idea is to limit the higher harmonics to the ones 
described by whatever formula you use to generate the waveforms, but if 
you eliminated all of them them you would just have a sine wave again 
;-) So what you get is considerably less aliasing, but without 
oversampling and filtering you will still get some.

Of course I'm no DSP guru, perhaps someone more mathematically inclined 
could give a better answer.

Best!
