Summarize this article for a 10 years old


PulseAudio is a network-capable sound server program distributed via the freedesktop.org project. It runs mainly on Linux, various BSD distributions such as FreeBSD and OpenBSD, macOS, as well as Illumos distributions and the Solaris operating system. It serves as a middleware inbetween applications and hardware and handles raw PCM audio streams.[5]

PulseAudio is free and open-source software, and is licensed under the terms of the LGPL-2.1-or-later.[4]

It was created in 2004 under the name Polypaudio but was renamed in 2006 to PulseAudio.[6]

PulseAudio has since been succeeded by PipeWire, which provides a compatible PulseAudio server (known as pipewire-pulse), and PipeWire is now used by default on many Linux distributions, including Fedora Linux, Ubuntu, and Debian.[7][8][9]
