Hypermpd is a latency-optimised fork of MPD version 0.25. It treats the audio pipeline as a real-time signal processor and focuses on proper decoding together with bit-perfect output.
The fork includes real-time audio threads, a bit-perfect short-circuit path through the filter chain, SCHED_FIFO scheduling on every audio path, a 25 ms ALSA buffer default, a configurable PipeWire ring buffer, and a kqueue event backend for BSD. These changes reflect a low-level approach that prioritises precision and low latency. The degree of modification is substantial enough that the maintainer does not plan to merge changes back to the upstream project.
Hypermpd is delivered as source code hosted on sourcehut. Installation proceeds by running configure followed by ninja -C build and then sudo ninja -C build install. A default configuration file is placed at the system configuration directory, typically /usr/local/etc/hympd.conf. The project is licensed under a combination of BSD-2-Clause, GPL-2.0-or-later, ISC, and LGPL-2.1-only terms.
In the Developer Tools space, ~bhyvxe/hypermpd - hypermpd takes a focused approach. It focuses on achieving high-fidelity, low-latency, bit-perfect audio playback with precise real-time processing in a music player daemon. It is built as an open-source project for audiophiles and developers seeking advanced open-source music server software. The project is open source (Open Source). It ships for the web, Linux, and the command line.
~bhyvxe/hypermpd - hypermpd first shipped in 2026. Among its 5 catalogued features are Real-time Audio Threads, Bit-perfect Playback, and Low Latency.
