Audio is an important point in a linux desktop environment
## Pulseaudio
## Sound Server
[Pulseaudio](https://www.freedesktop.org/wiki/Software/PulseAudio) is the go-to
audio server program for linux distributions.
A sound server is software that manages use and access of audio devices.
The following is a list of available sound servers.
## Noise cancellation
Noise cancellation can be easily achieved by installing
[Noisetorch](https://github.com/lawl/NoiseTorch).
After the installation modify the `Voice Activation Threshhold` to your needs.
## Pipewire
- [PulseAudio](./pulseaudio.md) is the go-to sound server program used for
linux.
- [Pipewire](./pipewire.md) is a modern graph based sound server.
[Pipewire](https://pipewire.org) is a graph based processing engine for
`pulseaudio` and `JACK`.
It makes improvements for the input and output handling.
### Installation
If the current audio server program running is `pulseaudio`, you can just
install `pipewire-pulse` (on Arch-based distros or according packages on other
distros) and pipewire is running.
Make sure to restart to be sure everything is running correctly.
## Noise cancellation
### Noise cancellation
Removing noise can be achieved by using
sound processing software options for [sound server](#sound-server).
An example for this is the noise reduction included in
[easyeffects](/wiki/linux/easyeffects.md#noise-cancellation) for Pipewire.
Noise cancellation can be easily achieved in `pipewire`-style by installing
[easyeffects](https://github.com/wwmm/easyeffects).
Make sure to check the box `Process all Inputs` and `Process all Outputs` to
route everything through `easyeffects`.
Make log out of your system afterwards.
To enable noise cancellation navigate `Inputs` and click `Plugins`.
After that click `Add Plugin` and select `Noise Reduction`.
As an alternative software explicitly made for the reduction of noise can be
installed.
Belonging to the latter option noise cancellation can be easily achieved by
installing [Noisetorch](https://github.com/lawl/NoiseTorch).
After the installation modify the `Voice Activation Threshhold` to your needs.

# Easyeffects
[Easyeffects](https://github.com/wwmm/easyeffects) is a free and open-source
GUI-software for applying sound effects and filters on input and output audio
streams.
Easyeffects uses [Pipewire](./pipewire.md) as
[sound server](/wiki/linux/audio.md#sound-server).
## Installation
Easyeffects can be installed in most distributions by installing the
`easyeffects` plugin.
An installation via [Flatpak](./flatpak.md) is also possible.
## Usage
Easyeffects can apply `Effects` to input and output sound.
### Noise cancellation
Noise cancellation can be achieved by installing
Easyeffects.
Make sure to check the box `Process all Inputs` and `Process all Outputs` to
route everything through `easyeffects`.
Make log out of your system afterwards.
To enable noise cancellation navigate `Inputs` and click `Plugins`.
After that click `Add Plugin` and select `Noise Reduction`.
### Presets
Presets can be created by selecting `Presets`, setting the name and clicking the
`+` to save it.
It is then displayed in the list below from where it can be loaded or deleted.
Presets are saved in the directory `~/.config/easyeffects/input` and
`~/.config/easyeffects/output`.
#### Recommended Presets
The following is a list of presets that have been tested and only need slight
configuration to adjust them to the specific system.
- [tiyns voice input preset](https://github.com/tiyn/dotfiles/blob/master/.config/easyeffects/input/voice.json)
is a list of different effects to achieve an enhanced quality of microphone
sound for speach.

# Pipewire
[Pipewire](https://pipewire.org) is a graph based
[sound server](/wiki/linux/audio.md#sound-server).
## Installation
For clients that use the [PulseAudio](/wiki/linux/pulseaudio.md) API
`pipewire-pulse` (on Arch-based distros or according
packages on other distros) can be installed.
It will automatically remove unneeded and conflicting PulseAudio packages.
Additionally `pipewire-alsa` and `pipewire-jack` for JACK and Alsa clients are
available.
Make sure to restart to be sure everything is running correctly.
## Sound processing
For simple sound processing in the form of volume adjustment as well as setting
the default input and output devices `pavucontrol` can be used as a simple
mixer.
For further sound processing the easiest way to do so is using
[easyeffects](/wiki/linux/easyeffects.md) which features a wide range of effects
to apply to sound streams including noise reduction.
