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.
