A Linux desktop tool for managing, monitoring and configuring AES67 audio streaming with PipeWire.
sync67 does not replace patchbay tools like qpwgraph, helvum or coppwr. Those are used alongside sync67 for audio routing and patching.
- ptp4l start/stop with live terminal output
- Sync indicator (traffic light: green ≤200ns, yellow ≤1000ns, red) + port state
- Interface optimization (gro/gso/tso/sg, rx-usecs, PHC reset, multicast, WoL disable)
- PTP4L Config Editor: format-preserving GUI for
/etc/linuxptp/ptp4l.conf(119 parameters, 7 tabs, auto-detected supported params) - phc2sys: start/stop with status ampel + config editor, auto-detected PHC device
- pipewire-aes67 start/stop with live terminal output, verbose mode toggle
- Stream health monitor with DSP load and log-based severity (green/yellow/red)
- AES67 Config Editor: format-preserving GUI for
pipewire-aes67.conf(40 parameters, 4 tabs, RTP Sink multi-instance, stream.rules raw editor)
- Sample rate / quantum control with Apply/Reset/Refresh
- Node table with tree structure (ID, status, name, quantum, format, channels, DSP, xruns, rate)
- Xruns counter (click to reset), DSP load bar, latency display
- Quick-Start: single-button start/stop with correct ordering
- Optional phc2sys integration (checkbox, default off)
- Start: ptp4l → (phc2sys) → AES67, polls each stage until ready
- Stop: AES67 → phc2sys → ptp4l
- System status overview (PTP, phc2sys, AES67, PipeWire)
- PTP + phc2sys + AES67 health traffic lights + xruns + DSP
- Version block with minimum version checks
- Routing tool launchers (qpwgraph, helvum, coppwr) – native + Flatpak + AppImage
