Helvum is a GTK-based patchbay for pipewire, inspired by the JACK tool catia.

Caution

Helvum is currently not actively maintained. If you are interested in maintaining the project, please see https://gitlab.freedesktop.org/pipewire/helvum/-/issues/137

Features planned

• Volume control
• "Debug mode" that lets you view advanced information for nodes and ports

More suggestions are welcome!

Building

Via flatpak

If you don't have the flathub repo in your remote-list for flatpak you will need to add that first:

$ flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

Then install the required flatpak platform and SDK, if you dont have them already:

$ flatpak install org.gnome.{Platform,Sdk}//45 org.freedesktop.Sdk.Extension.rust-stable//23.08 org.freedesktop.Sdk.Extension.llvm16//23.08

To compile and install as a flatpak, clone the project, change to the project directory, and run:

$ flatpak-builder --install flatpak-build/ build-aux/org.pipewire.Helvum.json

You can then run the app via

$ flatpak run org.pipewire.Helvum

Manually

For compilation, you will need:

• Meson
• An up-to-date rust toolchain
• libclang-3.7 or higher
• libadwaita-1 and libpipewire-0.3 development packages and their dependencies

To compile and install, run

$ meson setup build && cd build
$ meson compile
$ meson install

in the repository root. This will install the compiled project files into /usr/local.
