mark_gamache Posted February 10, 2020 Share Posted February 10, 2020 This has been discussed on other threads, but I would like to start one dedicated to the topic of using the Helix as a low latency interface. I've not been able get < 10ms latency running any sample and/or buffer settings. This has been supported by others reporting similar results. To get close you have to run 96K/64 samples. Running 96K/64 results in ~10.6ms of latency, but because you have to run 96K/64 samples it puts pressure on the computer I/O and creates buffer under-runs (the random noise you hear if the buffer is not filled). At a more reasonable setting of 48K/64 samples the latency is 13.2ms (all measured by the RTL utility). Note: my cheap Presonus USB interface is less than half that latency at the same settings. Question #1: Is this due to the latency compensation built-in for each external loop (to account for the analog-to-digital latency on each loop)? Question #2: Are there any tricks or settings we can use to reduce the latency I know I can monitor in near real-time via the helix, that's not what I am looking for here. thanks for any insight people might have, mark (note: I am using a Windows 10 laptop with an i7 processor and 32Gigs Ram) Quote Link to comment Share on other sites More sharing options...
