Hello,
I've been having this issue with zita-a2j launching into 100% CPU usage
fairly frequently when I am running Carla, one VST (Audeze Reveal Plugin),
and using Ubuntu Studio 19.04.
Has anyone else seen this kind of behavior before and knows what might be
happening?

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!
Thank you in advance,
Alex

Hi all.
Tomorrow it's the scheduled meeting at c-base again. I don't know if
I'll make it (I've stayed home from work today not feeling great), but
maybe Louigi or Robin can gather people?
Cheers

Hello All,
i have a special little audio problem with kdenlive which is annoying me
a lot, perhaps you can reproduce it or have an solutiuon:
I like to do video cuts exactly synchronized with music song beats. So i
would like to "tap in" the beats with markers before cutting to have the
cut positions to snap to. That's not possible on my system, i always
have about 500ms of delay when i listen to the music track and tap in
the beats. So the markers are always a little to late and out of sync...
Can you reproduce this? Do you have an idea?
I am on Arch latest kernel, KDE, Ryzen System, tried it on Pulseaudion
and Firewire external Audio Interface, Same Problem.
Thanks for ideas, Daniel.

Hello!
I am familiar with this error you described. What is the SSD's file system
formatted to? I get the same error when writing to my NTFS partition. I
can't remember where I read this but it is best to record to ext4 or
another more Linux friendly format.
Hope this helps!
Best,
n!
Hey hey,
I have had issues with Aeolus for a while now, but always let it go due to
other priorities.
Having attacked it again, I find that this problem persists both in the
installed package from Arch Linux, version 0.9.7 and a freshly downloaded and
compiled tarball from kokkinizita.
It seems that Aeolus segfaults the moment that it calls rl_initialize, gdb
giving a point in libncursesw as the last stack frame before shutdown.
I don't understand the problem since all other programs running with ncursesw
and/or readline alone work perfectly.
I'd be glad for any pointers to further investigation or even straight
solutions.
Thanks and best wishes,
Jeanette
