## What it is

Helvum is a graphical patchbay for PipeWire, the system that handles sound and video on modern Linux desktops. It shows every app, microphone, speaker and camera as a box with ports, and the connections between them as lines. You drag between ports to connect them, for example to send one app's audio into a recording app, or to route a microphone to two places at once.

## Why it's here

- **See your audio.** When sound goes to the wrong place, the graph shows why.
- **Custom routing.** Connect apps and devices in ways the Sound settings can't.

## On CoreDesktop

CoreDesktop installs Helvum as a Flatpak from Flathub. Open it from the app grid. `update` keeps it current along with your other Flatpaks.
