JACK is a professional sound server daemon that provides real-time low latency connections for both audio and MIDI data between applications that implement its API. The API can be used through either JACK1 or JACK2.

PipeWire is described as 'Project that aims to greatly improve handling of audio and video under Linux. It provides a low-latency, graph based processing engine on top of audio and video devices that can be used to support the use cases currently handled by both PulseAudio and JACK' and is an app in the system & hardware category. There are seven alternatives to PipeWire for a variety of platforms, including Linux, Mac, Windows, BSD and Self-Hosted apps. The best PipeWire alternative is JACK Audio Connection Kit, which is both free and Open Source. Other great apps like PipeWire are PulseAudio, GStreamer, NewPlayer and Phonon.

PulseAudio is a sound server system for POSIX OSes, meaning that it is a proxy for your sound applications. It is an integral part of all relevant modern Linux distributions and is used in various mobile devices, by multiple vendors.



GStreamer is a library for constructing graphs of media-handling components. The applications it supports range from simple Ogg/Vorbis playback, audio/video streaming to complex audio (mixing) and video (non-linear editing) processing.
Advanced Linux Sound Architecture (known by the acronym ALSA) is a free and open source software framework that provides an API for device drivers for sound cards. Some of the goals of the ALSA project at its inception were automatic configuration of sound-card hardware, and...
