Hello People,
I have a strange problem with high latency for both Brutefir or JConvolver. My Jack settings are low and stable and the latency doesn't seem to tally with the partition size?
My Hardware:
Software:
Settings:
Results:
Brutefir Latency = 104mS, CPU Load = 55-60%
JConvolver Latency = 85mS, CPU Load = <5%
These latencies are measured inside Jack(Not using sound card IO) using a jack signal generator and a jack oscilloscope.
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!
Thank you in advance,
Alex

My Hardware:
- i5-8259U - Intel NUC
- 8GB DDR4
- PCIe SSD
- M-Audio - MTrack8
Software:
- Ubuntu Studio 19.04 - Have tried updated and fresh install
- 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:
Brutefir Latency = 104mS, CPU Load = 55-60%
JConvolver Latency = 85mS, CPU Load = <5%
