(see file LGPL for details) + +However, the server side has optional GPL dependencies. These include the +libsamplerate and gdbm (core libraries), LIRC (lirc module) and FFTW (equalizer +module), 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 the 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. + +In addition to this, if D-Bus support is enabled, the PulseAudio client library +(libpulse) MAY need to be licensed under the GPL, depending on the license +adopted for libdbus. libdbus is licensed under either of the Academic Free +License 2.1 or GPL 2.0 or above. Which of these applies is your choice, and the +result affects the licensing of libpulse and thus, potentially, all programs +that link to libpulse. + +Andre Adrian's echo cancellation implementation is licensed under a less +restrictive license - see src/modules/echo-cancel/adrian-license.txt for +details. + +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. These include the device reservation DBus protocol +and realtime kit implementations. + +A more permissive BSD-style license is used for LFE filters, see +src/pulsecore/filter/LICENSE.WEBKIT for details. + +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. |
