Still waiting for the parcel, but while I wait, I got hard numbers on latency.
Using my scope, I had 1 probe connected to a piezo mic, and another to the LED of the converter. This LED updates at 1KHz, the same rate as the USB update rate.
I then smacked the drum 50 times, and recorded the delay between the moment the piezo started to respond, and when the converter registered a hit. An example measurement:
After 50 hits, here are the results:
Average: 1.802ms
Median: 1.77ms
Std Deviation: 0.44454517
Min: 1.1ms
Max: 2.78ms
Rounding the max value up, I can confidently say that there is an absolute worst case 3ms lag. And average lag of 1.8ms. This is imperceptible. Lagfree = confirmed!
