pwmix - NetLinux Packages

A mixer-style view of PipeWire. Applications, devices and the links between them are shown as columns of channel strips with live volume and mute controls, and each application stream is matched to the desktop window it belongs to.

Why this package?

Graph editors such as qpwgraph show every PipeWire node as a freely placed box, and have no volume or mute controls; volume tools such as pavucontrol have no picture of the routing. pwmix is a new tool from netlinux-ai/pwmix that puts both in one window, in a fixed Sources / Middle / Sinks layout:

Level and mute per strip — mouse wheel over a strip changes its volume, the M button mutes it; changes are written straight to PipeWire.
Routing at a glance — links between strips are drawn live, and links that pass through helper filter nodes (for example an EasyEffects chain) are collapsed into a single dashed link.
Which window is that sound from? — application streams are matched to desktop windows through the process tree, the X11 window list and MPRIS media titles, so a stream shows the title of the window that is playing it.
Small and self-contained — one C++ binary drawn with Cairo and Pango on a plain X11 window; no Qt or GTK.

Note: early prototype — no distro package exists to conflict with. It needs an X11 session and a running PipeWire daemon. Not yet built for stable (Debian 12), only resolute. Known limits: a browser such as Chrome runs all its audio through one process, so its streams can be matched to the browser but not always to the individual tab; routing cannot yet be edited by dragging.
