equalizer's Introduction

pulseaudio-equalizer-ladspa

A LADSPA based multiband equalizer approach for getting better sound out of pulseaudio. This equalizer clearly is more potent than the (deprecated ?), optional one from Pulseaudio.

(this screenshot was taken with the materia theme enabled, it might look different on your system)

Dependencies

Meson ≥ 0.46 & Ninja
GTK+ 3
Python ≥ 2.7 or 3
PyGObject ≥ 3.30
SWH Plugins
Pulseaudio
bash & bc

Build & Install

meson build
cd build
ninja
(sudo) ninja install

Meson options

Meson options can be set during initial configuration e.g. meson build -Doptionname=value or within the build folder with meson configure -Doptionname=value.

python: Per default the build system will use the same python installation as meson does. Set this if you want to use a specific version or binary. See http://mesonbuild.com/Python-module.html#find_installation for valid names or paths.
purelib: Meson defaults to install python modules to the purelib folder but some distributions e.g. Debian and derivatives do not set it correctly. In that case it needs to be manually set to the correct path relative to the prefix e.g. -Dpurelib=lib/python3.6/dist-packages for Ubuntu 18.10

equalizer's Issues

allow choosing different presets for different outputs

This is a feature request: Allow user to pick different presets for different output devices.

Allow the user to add more bands when editing a preset?

Should allow a user to add more bands when editing a preset, as well as to change the frequency value of the current ones? I don't know if that's something we want to do as it would complicate the UI.

Perhaps we could add "New Preset" button and query the user on the no of bands there?

Add option to run pulseaudio-equalizer over root account

pulseaudio-equalizer not working on Puppy Linux which was uses root account by default. Can you please add option that allows pulseaudio-equalizer to run on root account?

pulseaudio-equalizer-gtk fails to load - ValueError: could not convert string to float

I tried this on Debian 9 and I have used kernelOfTruth:s pulseaudio-equalizer before I tried to run this. I followed the readme instructions.

The pulseaudiio-equalizer enable command runs fine, except that it never enables the equalizer.

If I run pulseaudio-equalizer-gtk then I get the following error:

Maybe this has something to do with previous configuration files or such, but I renamed equalizerrc* and also presets directory. I also ensured that there were no binaries from the other version left.

Make the equalizer a sink

The current approach is OK for a static configuration but it's unnatural and almost impossible to get working without tinkering with pa events once you move to a more dynamic setting. Nowadays Bluetooth devices come and go all the time. There are also removable USB cards.

The problem is that being a filter that sits on top of the current default sink makes the equalizer fail every time the current card is removed (because of USB disconnection or whatever). The natural approach would be to make the equalizer a sink that connects to the main card (this should be a parameter, though) and stays there forever, providing an equalized sink for every client wanting to get equalized output, sink which could also be made the default for the system if so desired. I still remember this was the approach to equalization in the good old ALSA days.

Now, I'm not suggesting to completely remove the "as filter" feature, but just saying that the default should be a new "as sink" behavior, which is what most users want for sure.

Equalizer doesn't update band count when loading a preset

The equalizer supports a dynamic number of bands (ex. 10 or 15 or 20 etc. different frequencies). The UI should be updated with the correct number of bands when loading a preset.

How to install for FreeBSD?

EDIT:

I got it working perfectly on FreeBSD 13.1.
Finally a proper EQ for system wide sound on FreeBSD.

All I had to do is install the usual dependencies, compile and make sure that default.pa is placed at ~/.config/pulse/ with the following texts nano into it:

load-module module-equalizer-sink
load-module module-dbus-protocol

Oddly it is using FreeBSD's OSS server rather than PulseAudio... works for me :)

Need new maintainer

Hey, we need some new maintainer(s). I haven't touched the project in a while and I am not that motivated to fix bugs. I will still help out and review patches but we need new people if we want to move anything forward.

@ljmf00 @ev1lbl0w @iK4tsu @BGameiro2000 @cpcmc anyone wants to help out?

Doesnt work

Speakers no make boom boom when i click the switch.

GTK issue?

https://i.imgur.com/mb4aG89.png

On Manjaro KDE. Not sure what the issue is honestly.

Pulseaudio Ladspa Mixer and Firefox

I have something going on with the sound in Firefox (73.0.1) on Debian 10. When I set the volume slider in the tray to 40% and then open Firefox, play a Youtube video and open the EQ and enable it, or vice-versa, open the EQ GUI, then open FF and play a video, it cranks the volume slider in the tray to 100%. (so it seems to take over the master). This happens with any preset.

However when I use any Chrome-based browser (or any other application like VLC etc), no such problem happens, it doesn't effect the master volume/volume slider.

I've also set to load the EQ Ladspa sink on startup after main sink loaded at the bottom of /etc/pulse/default.pa

When I don't run the EQ, and then run FF, it doesn't happen. Any ideas on what this could be?

Audio is muted every time I start the equalizer

I set the equalizer to auto-start when I log in, however now the audio is always muted when I log in. I can unmute it but it's annoying having to do that every time. How do I prevent it from muting the volume on startup? (I'm using KDE Plasma)

No uninstallation ability or instructions

Having removed the equalizer package from the system, Pulse Audio still shows a device

Feature request: add this to the repos!

Linux` equalizer-situation is an absolute mess !!!

Please please please please can someone take care this equalizer finds its place in every possible repository, please?
There is no usable equalizer atm, feels like a bad joke!

The last good one was the pulseaudio-equalizer-ladspa 2.7.0.5 in Webupd8-ppa - unfortunately not useable after Ubuntu 20.04, so useless. Same for every other Equalizer I tried so far, all complete crap and bullshit.

Please make a good Equalizer work again, community!

Redesign

Hi i am working on a tentative gnome 3 redesign of the application. This issue is more of a question if upstream is even interested in one or not.

Original design for comparison.

What I tried to do with this redesign is to get rid of the controls to the right of the equalizer panel and the advanced menu and move them either to the headerbar or the app menu to be more consistent with the rest of a modern gnome 3 desktop.

Both Keep Settings and Reset to defaults have moved to the app menu. I think Keep Settings is fine there. I am not really happy with the Reset to defaults option in general since it is pretty unclear to the user what gets reseted and what not. For now i want to keep it there till better more specific options are provided (e.g. reset option for preset changes that haven't been saved yet).

Changing EQ Enabled to a switch and moving it to the top right is consistent in how gnome-tweaks and gnome-control-center solved this for enabling/disabling a panel altogether. This also makes the window title displaying this state obsolete.

The explicit Apply Settings option has been removed. It was mostly useful to apply changed equalizer scales while in many other cases the application applies those settings automatically. The app now automatically applies settings on the button and key release events on the scales.

The presets text combobox is now the custom title of the headerbar. In theory this is great but has one big problem that it inherits from the original design. The popover isn't scrollable and will ignore your screen boundaries making some options not selectable if you have a long list of presets.
Long term it probably needs a customized combobox widget with a custom model. This would also make it possible to display additional information in the list e.g. if preset is a system or a user one. A rework of the presets into a proper class would probably be helpful here.

Both the Save Preset button and Remove user preset… option from the advanced menu are now preset sensitive buttons in the headerbar.

User presets can now be deleted directly when selected allowing to get rid of the filechooser dialog based system.

The save system works still like in the original app with all its flaws. It still isn't possible to overwrite an existing user preset. Typing the name of an existing preset will load it and overwrite any previously made changes.

e.g. assume you start with the Perfect EQ preset, after you change any scale the preset field will be empty and would fail silently if you try to save it without a name. Now you want to name your preset Perfect EQ personalized but once you typed Perfect EQ that preset would load and overwrite any changes you made.

I dabbled around with changing the save system but i think that it would be better to postponed after the presets and presets combobox have been reworked.

Flat preset does make sound louder

While enabling EQ with flat preset selected, then it sounds like whole volume is a little bit increased.

Sound clipping.

Enabling EQ even with "Flat" preset introduce sound clipping at any volume. I think that happens because by default ladspa_output.mbeq_1197.mbeq sink runs as float32le, while all my sound interfaces are s16le max. Settings in /etc/pulse/daemon.conf have no effect on it.

Is there a way to change that? I have no clipping without EQ at all.

Ubuntu 20.04
Thanks.

Add settings to optimize/decrease sound latency

OS: Fedora 33
Equalizer version: Git 2659d0f
Sound device: Analog (Sennheiser Game Zero), connected to the motherboard's output jack

When enabling this equalizer plugin, I get significant latency which is noticeable in fast-paced games. Are there any tunables I can use to decrease this latency? When the plugin is disabled, I get lower latency.

I'd be OK with trading higher CPU usage for lower latency.

Write config outside default.pa

It's common practice between users to store their dotfiles in a git repo. Saving app state in config files wreaks havoc with this practice since every time state changes a new commit is needed. Please allow to save state in an external file to be included from default.pa. This could be an option or simply the default behavior: for example, save your state in pulseaudio-equalizer.pa and just add the include line to default.pa.

New maintainer?

@larmedina75 do you want to officially maintain this? If so we could create an organization and move the repos there.

Per channel graphical equalization. [feature request]

Hey, I think it would be nice if it was possible to equalize channels differently for both channels.

Remember that files created by custom scripts have not been removed.

The equalizer still shows up as sink in pavucontrol etc and interferes with my sound even after reboot!

Add my ASUS UX430UA preset :)

Hey,
I thought it would be useful to add this preset. I did spend some time to make this preset for my laptop (using frequency sweeps). It sounds really good on a ASUS UX430UA, but maybe also on other laptops.

ASUS UX430UA.preset.zip

State of the UI part of the preamp scale

Currently the preamp value is read from settings or preset and saved to the settings or preset. A corresponding Gtk.Scale object is created and added to the UI but it is never shown so any UI related code regarding the preamp is basically dead code.

So my question here is if we should add the preamp scale back as visible widget or not. If not it is probably a good idea to remove any remaining UI code.

Mute key LED not working

Whenever I'm trying to mute audio using F6 key, the audio gets muted, but the LED does not blink.

My mute key LED works when switching to in-built audio as sound output via settings, but when I switch to LADSPA plugin equalizer as sound output, the LED does not blink.

System specs:
Machine: Hp notebook
OS: Arch Linux

How to configure after the installation?

How do I configure pulseaudio-equalizer-ladspa once it is installed? I've turned it on using the GUI, but nothing is taking effect. Are there something that I need to do?

Distorted sound with presets

Hi,

when I use presets I have distorted sound, because the gain is to high.
For example the preset Big Bass Boost increases the 50Hz 15db.

I solved the issue for me to just decrease every frequency 15db for this preset.
If this would be a preferred solution and get merged, I would change all presets.

Thank you really much for this great tool.
I have a Bose quiet comfort 35 and the preset really solves the bass problem for me and produces a great sound! :-)

Binary package not present in distros main repositories anymore?

Any reason for why pulseaudio-equalizer-ladspa is not present in major distributions' repositories anymore?
Is there a custom PPA that I can add that has this package?
Do you still have binaries packages for the older version present in Ubuntu Xenial around 2017-ish? I like that version more, because it doesn't immediately applies changes while you are changing values, you have to press button "Apply Changes".
But this new version seems to cause less stutterings with Pulseaudio, less bugs I guess, so well done :)
I just don't like the new UI, it's too easy to make mistakes adjusting boosts/cuts, the sliders move too fast, specially on crappy laptop touchpad.

Latest release 3.0.2 works fine.

Culprit lies in latest changes in handling of variables in pulseaudio-equalizer script.

f7e1765#diff-d860455b216e068fc7f2f55c34a6c3dfR87

Previous way of replacing spaces with commas through sed somehow trimmed leading space, but now leading space in variables ($RAWDATA1, $RAWDATA2) remains. This will corrupt equalizerrc to the point that pulseaudio-equalizer-gtk is not able to start.

[feature request] Possibility to select the speakers

Hi,

It would be nice if you could add an option to activate the equalizer only on certain speakers. I'm thinking in particular of bluetooth speakers.

If I run pulseaudio-equalizer enable when the system starts, the command controls the integrated speakers. To make it work on the bluetooth ones, I run the command with a delay.

Thank you.

per-app equalization? (feature request)

right now ladspa makes a sink that applies to all audio outputs and it would be nice if it could be configured what sinks it could apply to.
maybe it is possible already but im honestly an absolute noob when it comes to configuring pulseaudio with the conf files

Sound in Pidgin becomes messed using ALSA with equalizer enabled

As it says on the tin. Mind, I had no problems before and this is only a recent issue, which doesn't rear its head in a live session of Manjaro MATE but on the installed system — no matter what, without fail — the audio for Pidgin (and I presume other GTK applications) becomes messed up.

Had anyone else encountered this? And if so, what's the fix? I've spent the better part of a day reinstalling my system multiple times with no good result.

python shebang: should it use env?

System: Manjaro xfce.
I'm a user of anaconda, so when a run /usr/bin/pulseaudio-equalizer-gtk it tries to use anaconda's python and it fails because it doesn't have the correct dependencies installed.

Changing #!/usr/bin/env python3 for #!/usr/bin/python3 did the trick.

It should translate to a change in bin/pulseaudio-equalizer-gtk.in:
#!/usr/bin/env python@python_major_ver@ for #!/usr/bin/python@python_major_ver@

I don't know if there is any need to use env but this is my suggestion.

Feature request: Pipewire support

Are there any plans to make this excellent equalizer to work with pipewire?

I still use Pulseaudio - and this equalizer - on my desktop computer, but recently converted my laptop to pipewire, and, sadly, noticed that the pulseaudio-equalizer-ladspa does not work with pipewire. The main problem seems to be that it tries to access 'pacmd', which does not exist on pipewire systems. Pipewire devs don't seem to have any intention to include pacmd support for pipewire, either...

It would be a shame to lose this app, IMHO it is the best equalizer for Pulseaudio in existence.

Not working on Manjaro Gnome 18.04

Is not working on Manjaro Gnome Arch Linux.

pulseaudio-equalizer: wrong reading local settings

Before

# Convert spaces into commas
   PA_LADSPA_CONTROLS="${RAWDATA1// /,}"

we need to remove the leading space, because it is converted to a comma and the settings become broken.

# Remove leading space in settings
   RAWDATA1="${RAWDATA1/ /}"

Similar for RAWDATA2

Bad UX

Hi.

I'm enabling equalizer, setting up knobs, saving as new preset. Then I'm trying to tune up settings. As a result the preset name is clearing out and I cannot save the preset.

When I want to type a name of the preset (to save using same name), the application loads previously saved state during typing and destroys my last tunings.

So I cannot modify my preset.

Installation help

Hello friends,

I'm reconfiguring an old ACER ASPIRE 5750 for a friend.

I haven't installed Windows in order not to slow it down too much, and my choice of Linux Mint Cinnamon is the right one: the machine responds perfectly.

On the other hand, the sound isn't very good. In French we say: it sounds "like a saucepan"!

So I tried to install an equalizer by following this article.
The main problem is that this release doesn't offer any presets, which is nonsense!

So I searched the net and found your equalizer.
However, from a beginner's point of view, the installation instructions are addressed rather to a geek familiar with linux builds...

So, could you please go into a little more detail about the installation procedure?

Thanks in advance
Best regards - Jean-Paul

PS: don't hesitate to suggest another solution if this program is obsolete and/or incompatible with Mint.

Bug after the last update

I use Manjaro KDE latest version. After the last update, I need to open PulseAudio Equalizer all the time to keep the preset I choose, otherwise it goes back to the default preset after receiving a new audio stream.

Backup Current Equalizer

How do I backup the current EQ settings?

I have found the perfect EQ settings and I don't want to loose them.

New icon?

I think an icon would be a great addition to the project, if someone wants to draft something up.

Can equalizer start on boot?

I've installed the equalizer from the Manjaro repos.
I've created a curve for it that I'd like to always be on with my computer.
Is there a way to load the equalization at boot or at user login, preferably silently?
Thanks in advance.

Generated lines in default.pa

First of all: Thanks, thanks, thanks for finally providing us a working EQ for pulseaudio (I use it on the Raspberry Pi) !!

I got an issue with the lines generated by pulseaudio-equalizer enable-config:

In contrast, pulseaudio-equalizer enable works without any problems.

BTW:
Shouldn't it be .fail instead of .endif?

crackling sound when equalizer enabled

While equalizer is enabled, then any quick repeatable system notifications are crackling (like volume up, down). Without Equalizer, everything is fine.

While it's not nice to hear, it sounds like in the case speakers are not able to handle the sound. In this case, I do not really know if such glitches are because of equalizer, or I have to adjust presets/volume to not break the speakers.
