|Here's the unique tool for finding the truth about latency.
The Ploytec Latenc-o-meter generates a "click" signal on its analog output (the red cinch connector) and waits until it returns on the input (the black cinch connector).
In the meantime it samples that input on its A/D converter running at 100kHz samplerate in order to get this amazing accuracy: The measurement range goes from 0.01ms to 999.99ms!
The red button switches it on while pressed, new clicks are generated every few seconds. It runs from a 9V battery which is easy to replace (but should last for ages depending on your application).
We use it for our development of external USB2 soundcards and drivers, but there's tons of further applications including checking your studio setup, testing digital audio equipment and last not least VoIP.
