Mixologist

A utility for mixing your audio between programs. Experience changing audio levels without having to dig through a volume mixer wtih quick and easy program based filtering.

Mixologist uses PipeWire to rewire connections on the fly to two separate channels as you see fit. Raise the volume of your discord call and lower the volume of your game without having to touch any audio settings.

Warning

This is ALPHA software, breaking changes will be kept to a minimum but are possible

Getting Started

Mixologist can be installed via the latest release.

Building from Source

Dependencies:

• Odin
• libpipewire
• sdl2 (for mixgui)
• systemd (if using systemd unit)

$ make
$ sudo make install

Usage

If using systemd, the Mixologist daemon (mixd) should start at launch. mixcli can then be used as shown:

Flags:
	-add-program:<string>, multiple     | name of program to add to aux
	-remove-program:<string>, multiple  | name of program to remove from aux
	-set-volume:<f32>                   | volume to assign nodes
	-shift-volume:<f32>                 | volume to increment nodes

If you wish to have hardware volume control, set keybinds in your desktop environment to the corresponding mixcli command that you wish to invoke. For example:

Shift + F10 -> mixcli -set-volume:0 #resets volume
Shift + F11 -> mixcli -shift-volume:-0.1 #balance one way
Shift + F12 -> mixcli -shift-volume:0.1 #balance the other way

Volume is a single value that can range from -1 to 1 where:

• 0 is both channels at full volume
• 1 is only the programs in the "program list"
• -1 is only every other program

Configuration

The config file resides at ~/.config/mixologist/mixologist.conf and is a list of programs (one per line). This represents the set of programs you wish to isolate. The config file is hot-reloaded and can be modified by mixcli or just editing it with your favorite text editor.
