For example, if I have a 64 sample block and all the samples in that block are zeros except for sample 30 which is a one, and I wanted to shift all samples up 30 bins (with wrapping) so that now all samples in this block are zeros except bin 60 which is a one, how would I do that (without writing my own external)?
use both [lrshift~ 30] and [lrshift~ -34]. You need two because it's zero-padding instead of wrapping.
the helpfile for [lrshift~] is not available through usual means because someone made a typo in the filename five years ago or something.
If I understand the basic objects correctly, a simple [+~ 30] would turn the sample block above from all zeros except bin 30 which is a one into a sample block of all 30's except bin 30 which would now be a 31, right?
yes.
Essential, my question is are there bitwise operators such as [>>] and [<<] exept working on samples instead of bits. Interestingly, convolution is basically an audio rate 'and' [&&~], right?
no, convolution is a bunch of sample-wise shifts and [*~] and [+~] together (as many as there are values in the convolution kernel).
