PulseAudio is a sound system for POSIX OSes, meaning that it is a proxy for your sound applications. It allows you to do advanced operations on your sound data as it passes between your application and your hardware. Things like transferring the audio to a different machine, changing the sample format or channel count and mixing several sounds into one are easily achieved using a sound server. PulseAudio is designed for Linux systems. It has also been ported to and tested on Solaris, FreeBSD, NetBSD, MacOS X, Windows 2000 and Windows XP.

This build for Windows is from version 1.1 and was compiled on 2011-10-25.

To install PulseAudio, run the following command from the command line or from PowerShell:

C:\> choco install pulseaudio

To upgrade PulseAudio, run the following command from the command line or from PowerShell:

C:\> choco upgrade pulseaudio


  • legal\GPL
  • legal\LGPL
  • legal\LICENSE.txt Show
    All PulseAudio source files are licensed under the GNU Lesser General Public
    License. (see file LGPL for details)
    However, the server side has optional GPL dependencies.  These include the
    libsamplerate (for core libraries) and bluez (for the bluetooth proximity helper
    program) libraries, although others may also be included in the future.  If
    PulseAudio is compiled with these optional components, this effectively
    downgrades the license of the server part to GPL (see file GPL for details),
    exercising section 3 of the LGPL. In such circumstances, you should treat the
    client library (libpulse) of PulseAudio as being LGPL licensed and the server
    part (libpulsecore) as being GPL licensed. Since the PulseAudio daemon, tests,
    various utilities/helpers and the modules link to libpulsecore and/or the
    afore mentioned optional GPL dependencies they are of course also GPL licensed
    also in this scenario.
    Andre Adrian's echo cancellation implementation is licensed under a less
    restrictive license - see src/modules/echo-cancel/adrian-license.txt for
    Some other files pulled into PA source (i.e. reference implementations that are
    considered too small and stable to be considered as an external library) use the
    more permissive MIT license. This include the device reservation DBus protocol
    and realtime kit implementations.
    Additionally, a more permissive Sun license is used for code that performs
    u-law, A-law and linear PCM conversions.
    While we attempt to provide a summary here, it is the ultimate responsibility of
    the packager to ensure the components they use in their build of PulseAudio
    meets their license requirements.
