PipeWire Quantum vs XRun Threshold: The 2026 Dataset (Published Methods, Published Raw Numbers)
Quantum vs XRun data for PipeWire in 2026. Five hardware configurations, four quantum values each, all methods published. Use the numbers to calibrate your own setup.
BenchmarkingRound Trip Latency Leaderboard 2026: USB Audio Interfaces Tested on Linux With a Reproducible Method
USB audio interface latency varies enormously on Linux. Here is a 2026 leaderboard of measured round-trip latency for common interfaces, with the exact test method documented so you can verify the numbers.
Library NotesMIDI 2.0 on Linux 2026: PipeWire UMP, Kernel Support Reality, and Safe Fallbacks for Controllers and DAWs
MIDI 2.0 on Linux is partially here. PipeWire has UMP transport, the kernel has ALSA UMP, but DAW and controller support lags behind. Here is what works today and what fallbacks to keep in place.
DAW WorkflowREAPER on PipeWire in 2026: Low Latency Setup and What To Do When XRuns Hit Mid Session
REAPER on Linux runs well when configured properly. Here is how to set it up on PipeWire for low latency recording, and what to do when XRuns appear mid session without losing takes.
DAW WorkflowBitwig Studio 6 on Linux: Performance, Audio Routing, and a Sane PipeWire Workflow (2026)
Bitwig Studio 6 is one of the few commercial DAWs with real Linux support. Here is how to configure it for stable performance on PipeWire and avoid the routing and latency traps.
