LICENSE: add a clarification
2016-12-29 05:35:14 +08:00
All PulseAudio source files, except as noted below, are licensed under the GNU
Lesser General Public License. (see file LGPL for details)

Update LICENSE. Some of the license wording was less than clear. Try to clarify the different GPL 'downgrade' scenarios but also be generic to ensure that those packagers where GPL is a problem check thoroughly before they ship. Inspired by comments from Brian Cameron @ Oracle via fdo#41822

However, the server side has optional GPL dependencies. These include the
bluetooth: Remove module-bluetooth-proximity module-bluetooth-proximity has not worked for quite a while, since it uses pre-BlueZ4 APIs. Nobody complained since then, which is a good indication that it doesn't have much users. Even the original commit message refers to it more as a toy than as something of great use: "add new fun module that automatically mutes your audio devices when you leave with your bluetooth phone, and unmutes when you come back" Removing it we completely remove the dependency on libbluetooth.

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.

doc: Update LICENSE to reflect optional libpulse dep on libdbus
2013-06-25 11:50:03 +08:00
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.
echo-cancel: Add alternative echo-cancellation implementation This adds Andre Adrian's AEC implementation from his intercom project (http://andreadrian.de/intercom/) as an alternative to the speex echo cancellation routines. Since the implementation was in C++ and not in the form of a library, I have converted the code to C and made a local copy of the implementation. The implementation actually works on floating point data, so we can tweak it to work with both integer and floating point samples (currently we just use S16LE).
2010-09-07 16:13:58 +08:00
Andre Adrian's echo cancellation implementation is licensed under a less
restrictive license - see src/modules/echo-cancel/adrian-license.txt for
details.

considered too small and stable to be considered as an external library) use the

lfe-filter: Import code from the Chrome OS audio server The chrome OS audio server has some already existing code, which has been made available under a BSD-style license, which should be safe to import by us. Signed-off-by: David Henningsson <david.henningsson@canonical.com>

A more permissive BSD-style license is used for LFE filters, see

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.
