I'm using pulseEQ on Ubuntu 20.04. I get qpaeq up and running and the GUI isn't great. I have sliders with no axis values. I download my equalizer preset from github/autoEQ, but there's no good way for me to import it. I could do it manually, but even then I can't see what gain value the slider is making, there's no sense of scale at all.
I was hoping, then, that when I save a preset, it would make a file in plain text, which I could then open and enter my preset that way. But I haven't been able to find it.
I look for qpaeq files nearby to the binary:
simon@simon-MacBookPro:~$ which qpaeq
/usr/bin/qpaeq
simon@simon-MacBookPro:~$ ls /usr/share | grep qpaeq
simon@simon-MacBookPro:~$ ls /usr/* | grep qpaeq
qpaeq
The only thing with the name qpaeq in it in /usr is the binary itself. I don't think there are any related files then in /usr
Any clues in /etc ?
simon@simon-MacBookPro:~$ ls /etc | grep qpaeq
simon@simon-MacBookPro:~$ ls /etc | grep pulseaudio
simon@simon-MacBookPro:~$ ls /etc | grep pulse
pulse
simon@simon-MacBookPro:~$ ls /etc/pulse
client.conf client.conf.d daemon.conf default.pa system.pa
simon@simon-MacBookPro:~$ ls /etc/pulse/client.conf.d
01-enable-autospawn.conf
simon@simon-MacBookPro:~$ cat /etc/pulse/client.conf.d/01-enable-autospawn.conf
cat: /etc/pulse/client.conf.d/01-enable-autospawn.conf: No such file or directory
Looking through the .conf and .pa files, they look like they came with the package and like nothing special.
So I created a preset with a unique name and then went to root and did
simon@simon-MacBookPro:/$ sudo find . -name presetFindMe
find: ‘./run/user/1000/doc’: Permission denied
find: ‘./run/user/1000/gvfs’: Permission denied
find: ‘./proc/68262/task/68262/net’: Invalid argument
find: ‘./proc/68262/net’: Invalid argument
and it came up empty.
I found the pid of qpaeq and then looked at it's open files in /proc, and this is what I get:
simon@simon-MacBookPro:~$ ls -l /proc/54513/fd

Not promising.
Maybe if I look into pulse itself:
simon@simon-MacBookPro:~$ ps aux | grep pulse
simon 1830 4.0 0.2 4333464 35376 ? S<sl 09:39 6:23 /usr/bin/pulseaudio --daemonize=no --log-target=journal
root 52858 0.0 0.1 505992 17176 ? S<l 11:05 0:00 pulseaudio --start
simon 96051 0.0 0.0 9040 2692 pts/5 S+ 12:16 0:00 grep --color=auto pulse
simon@simon-MacBookPro:~$ ls -l /proc/4333464/fd
ls: cannot access '/proc/4333464/fd': No such file or directory
simon@simon-MacBookPro:~$ ls -l /proc/505992/fd
ls: cannot access '/proc/505992/fd': No such file or directory
I'm relatively new to linux. Am I even on the right track? Am I SOL? Would I be better off looking into the source code?
