Hello People, I have a strange problem with high latency for both JConvolver or BruteFIR. My Jack settings are low(3ms) and stable and the latency doesn't seem to tally with the partition size? My Hardware: i5-8259U - Intel NUC 8GB DDR4 PCIe SSD M-Audio - MTrack8 USB Sound Software: Ubuntu Studio 19.04 - Have tried updated and fresh install also a blank Debian 10.1 Jconvolver 0.9.3-2 BruteFIR 1.0o-1 Jackd2 1.9.12 Settings: Jack Settings - 48KHz 64Buffer 3Period BruteFIR - 7 Filters each 8192 Taps, These are each split into 512sample partitions Jconvolver - 7 Filters each 8192 Taps, These are split into 64sample partitions Results: JConvolver Latency = 85mS, CPU Load = <5% Brutefir Latency = 104mS, CPU Load = 55-60% These latencies are measured inside Jack(Not using sound card IO) using a jack signal generator and a jack oscilloscope. But also verified externally. I dont understand why I am getting such long latencies, I would be very grateful if anyone could shed some light on why the latencies are so long and even more grateful if you could share how to fix it!
