# Welcome to PulseAudio!
**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. It performs advanced operations on sound data as it passes between your application and hardware. Things like transferring audio to a different machine, changing the sample format or channel count, or mixing several sounds into one input/output, are easily achieved using PulseAudio.
Check out our [[About|Software/PulseAudio/About/]] page for more details, and our [[FAQ]] for details about commonly asked questions.
# Support and Development
## Linux systems
PulseAudio for Linux has an active [[community|/Software/PulseAudio/Documentation/User/Community]] which you can find support and engage with the developers. [[Upstream|https://en.wikipedia.org/wiki/Upstream_(software_development)]] support is only for Linux systems.
## Non-Linux systems
Though PulseAudio was designed for Linux systems, it has also been ported by *independent* developers to Solaris, FreeBSD, NetBSD, MacOS X, Windows 2000 and Windows XP. We do not currently offer support for non-Linux systems, but patches for these systems are welcome and appreciated. If you're having issues on those systems, you must fix them yourself. Windows binaries are not provided by this site.

## Call for Developers!
PulseAudio is a large project maintained by a small yet passionate group of volunteers! Our development team currently consists of three individuals who maintain the code-base in our free time! (This probably amounts to less than one full time developer.) Important bug reports and patch submissions are often handled more slowly than we would like. For this reason, we are actively seeking additional members of our team!
If you are interested in becoming a maintainer yourself, please contact us! Visit our [[Community|https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/Community/]] page for places you can find us, or send email directly to Tanu Kaskinen (email@example.com), Arun Raghavan (firstname.lastname@example.org) and/or Georg Chini (email@example.com).
