Parametric EQ for Linux
I have been looking everywhere for a parametric EQ that runs on Linux. Does anyone know where to find it.

Thanks in advance.

For music playback only (where a player would suffice) or system-wide?
Listen to the music, not the media.

On Debian Stretch
Code: [Select]
apt-cache search equalizer | grep pulse
pulseaudio-equalizer - Equalizer sink module for PulseAudio sound server
I guess thats not a parametric one?

for system wide use QPAEQ
Here's how the equalizer looks like:

it is not a parametric but If you resize the window horizontally, you'll notice that more bands show up so using it, you have very high control


equalizer is integrate to pulseaudio.
only need is QPAEQ interface

in ubuntu  terminal do this:

( install depencency )
sudo apt-get install python-dbus python-qt4 python-qt4-dbus pulseaudio-utils   

(get qpaeq)
wget http://cgit.freedesktop.org/pulseaudio/pulseaudio/plain/src/utils/qpaeq -O /tmp/qpaeq

( install qpaeq in  /usr/local/bin/ )
sudo install /tmp/qpaeq /usr/local/bin/

( open /etc/pulse/default.pa with text editor , for exemple gedit )
sudo gedit /etc/pulse/default.pa

( at the bottom of the file, add this:)
### Load the integrated pulseaudio equalizer and dbus modules
load-module module-equalizer-sink
load-module module-dbus-protocol

reboot

now you can find this new output in sound control (fftbase equalizer ) , select it


type qpaeq in terminal and make mod to sound.

VERY IMPORTANT: if you have click and pops in sound make this mod to default.pa

find this line:
load-module module-udev-detect

change to:
load-module module-udev-detect tsched=0

reboot

Install some ladspa plugins packages that you probably can find in standard repos (these plugins can be used with Audacios or QMMP, for example). In these ladspa sets there are one or two parametric equalizers there.

Player-wise, Deadbeef's own EQ also features some 18 bands - which will cover most ppl's needs, IMO.

System-wide, there's 2 options I've found for a parametric EQ on Linux. I use a PulseAudio LADSPA plugin, you'll likely have to compile it but it has fairly minimal dependencies, instructions here:
https://github.com/bmc0/dsp/wiki/System-Wide-DSP-Guide

Alternatively, here's another writeup for a 10 band parametric EQ, this requires installing JACK (as PulseAudio doesn't yet seem to support LV2 plugins) and interfacing it with PA:
http://jamesudiljak.com/blog/jekyll/update/2016/09/07/eq10q.html

Hope these help! There's also the CALF Studio Gear plugins which include a couple of parametric EQ utilities for audio processing software, but I haven't found a way to use them system-wide.

Some members, who don't have problems with reading comprehension, provided excellent answers. The question was precise enough for them.

But I do have a question for you. Your posts are largely devoid of any useful information, so I'd like to block you. Can you kindly advise how?

Says the cocky troll* who's been here for a couple of weeks but has been desperately trying to cause a stir with his/her "revolutionary" posts to a member who's been here practically4 from day one.  Not that long membership guarantees anyone to be above the law, but you haven't obviously read 1% of his +1.7K posts to personally attack him, have you?


* who's been already advised on actually reading previous debates before trying to reinvent the wheel without having a grasp of what this place is actually all about!

Are you sure of yourself, sir/ma'am?

mmrkaic couldn't be more obvious what it is here for with its 100% fitting to the pattern reaction so i left it uncommented.

We had a productive discussion in this thread before wombat and includemeout started interfering with their insults. Nobody even mentioned them -- they felt entitled to start insulting me. That is a fact.

You believe that your forum "seniority" gives you special status. Apparently it is OK for wombat to attack me personally, because he is an old timer (with 1.7k posts, wow). But when I point out that HE STARTED with personal attacks, all hell breaks loose and his pal runs to his defense.

You're right. Leave him at it.

OK, so now that you two so nicely agree, could you please stop polluting my thread with your nonsense? Nobody here has any use for your insolent interventions.
