True sub-oscillator?


#1

Is audio-rate division possible with clever patching or is it something that could only be done with a custom object? I'm thinking along the lines of the dist/inf, but only responding to every other zero-crossing.

EDIT: Hmm, I think it would at the very least require some audio rate versions of objects that only exist as k-rate and even then it would be susceptible to aliasing. I'm guessing it'd be a custom object type of job.


#2

The fact you're going down an octave might help mitigate aliasing.

True, but still, audio rate versions of dividers and things would still be changing right on a sample boundary so I think you'd get jitter and aliasing. It might not be too loud but it would be there. I think a custom object is definitely the way to go, I bet it would be doable by adapting the dist/inf, but first I need to get around to learning how to code axo objects. Still not got my head around doing this kind of stuff with fixed point maths.


#4

Me neither. I'm used to working with GPU shaders, where it's floating point all the way, and everything is in the 0 > 1 range. Make interpolation equations etc. much simpler.

look at my octaver patch for an implementation (with some custom objects)
