I can't comment on the usability of such a plugin in combination with
jack, however, here is a screenshot:

Hi Mauro,

No, thanks for the suggestion, but I don't see an option to set an EQ in there, 
am I missing something?--

Re: [ubuntu-studio-users] EQ with JACK

2017-12-01 Thread Thomas Pfundt 
Hi Ralf,

thank you for your reply. Using Ubuntu Studio 16.04 currently, but I am 
planning to do a full re-install & system upgrade to 17.10 around Christmas/New 
Year soon, so I'll probably reconfigure my setup then.

I don't use jackdbus, currently. I can get JACK and either Calf and/or JackRack 
started simultaneously while using the startup-script options in qjackctl and 
set all necessary connections in the patchbay, but my issue is basically that 
the plugin-windows need to stay open constantly and accidentally closing one 
will result in errors with the preset connections and I'll have to restart it. 
This has happened to me a few times already, as I'm used to close all 
unnecessary windows and keep my workspace clean.

Also, I don't like the fact very much of having full-blown plugin hosts open 
constantly when all I need is one single parametric EQ to flatten my room 
acoustics, which is around 0,1% of the functionality.

I thought that maybe there was an alternative to this that can be used with 
JACK. Maybe a dedicated EQ that can be set once and then moved to the systray 
or just runs quietly in the background? I haven't found anything yet, 
unfortunately. I read somewhere that there also is an option to enter 
EQ-frequencies into ALSA somehow, but I can't find anything on that for the 
life of me, either. I also don't know specifically what to search for.

Since EQ is rather essential when seriously trying mix and master audio, I 
thought I'd ask around how you guys manage that. Maybe I haven't thought of 
something yet, but my current solution is not very practical.--
