   4 However, the server side links to the GPL-only library 'libsamplerate' which
   5 practically downgrades the license of the server part to GPL (see file GPL for
   6 details), exercising section 3 of the LGPL.

   8 Hence you should treat the client library ('libpulse') of PulseAudio as being
   9 LGPL licensed and the server part ('libpulsecore') as being GPL licensed. Since
  10 the PulseAudio daemon and the modules link to 'libpulsecore' they are of course
  11 also GPL licensed.

  13 Andre Adrian's echo cancellation implementation is licensed under a less
  14 restrictive license - see src/modules/echo-cancel/adrian-license.txt for
