I would like to measure the time of occurrence of waveform events (for example from adc~) with sample resolution. In other words, I would like to record at what sample index an event such as a threshold crossing occurred. The aim is to time events on various inputs relative to each other with sample accuracy.
I may be wrong, but I don't think things like vline~, timer or realtime can give me this accuracy. What I have in mind is something like threshold~, but that outputs the index at which a threshold-crossing event occurred.
Does such a thing exist?

there is always the possibility to use a subpatch with [blocksize~ 1]. but I did not use this often, because, it is cpu intensive... better to find a solution in the signal-domain. like with >~ from zexy in combination(*~) with a phasor~ or line~ you would get a signal vector, where you have only values on the bins, where the threshold is crossed. marius.
