If you are using a EWI 4000, you can trigger the EWI's audio output on an oscilloscope on one channel, then attach the other channel to your PC audio output. It should then be very easy to see the latency. Brad On 11/14/2015 12:19 PM, Ben Gonzales wrote: Hi all. How do you measure latency wi

Hi, By definition latency means the time difference between the "action begin" and "sound begin".  Applying to this case, "action begin" is "begin blowing" or "clapping hand". As a result, a precise way to measure the latency of wind controller would be: 1. You need a stereo recorder, one chan

Hi Ben, 2015-11-14 21:19 GMT+01:00 Ben Gonzales : > 1. How does one measure latency for a wind controller? An easier and more accurate way to measure the overall system latency could be to measure it while changing from one note to another: Use a sound card with two channel (i.e. stereo) input.
