Hey, I just wanted to share this patch I made.
I need to measure the delay in samples between two points in my patches, so I came up with this. I should say "blockwise" though, because the result is always multiple of the block size. Lowering the block size leads to less precise results, at least on my pc.
Even though I think it's enough for my purpose, do you think it could be improved?
Does exist an external that can do that?

Attached is a sample-precise latency meter which I made for testing loopback latency, but you can use it for finding latency values in Pd patches as well. It sends a single sample pulse and records the delayed result into an array, then finds the index number where the delayed pulse appears.
