>>> Check out the demo videos at onyx3.com/EDLM E-Drum Latency Meter was developed specifically for measuring latency in electronic drums. The app uses an audio adapter to connect to the input and output points of an e-drum system and provides automated and accurate latency measurements. EDLM app sends a trigger pulse to the module while simultaneously recording and waiting for the drum sound to arrive. It then calculates and stores the time difference between the two moments. This cycle is continuously repeated at different intervals as the accumulated data is used to estimate the average latency and jitter amounts. The app requires an external audio adapter or interface.
