It comes with several backends ([35]ALSA, [36]PulseAudio, OSS, [37]GStreamer, null) and is designed to be portable. It consists of the following parts: 1. libcanberra: the main library 2. libcanberra-gtk: some glue code to make it easier to use libcanberra from Gtk+ applications 3. libcanberra-gtk-module: a Gtk+ module that uses libcanberra-gtk to trigger input feedback event sounds For more information see [38]the original announcement. Current Status libcanberra is mostly feature complete. For now however it includes backends only for ALSA, PulseAudio, OSS and GStreamer. libcanberra has been declared [39]a blessed GNOME dependency. The OSS driver is incomplete: only sound files that are in a format natively understood by the sound card are supported. If the sample type, channel map or sampling rate of the sound file are not supported by the sound card no automatic conversion will take place and the file will not be played. Also note that the OSS backend is most likely incompatible with OSS4, due to subtle incompatibilities between OSS4 and the OSS 3.x. It is recommended to always take the "shortest" path from libcanberra to the audio device. I.e. don't use the GStreamer plugin if libcanberra supports the final output target natively. Besides being more resource-friendly and less error-prone, some advanced functionality might get lost with each layer you add to your stack. For example: while you could use libcanberra's Gstreamer backend to output to a PulseAudio server this will not be able to make use of sample cacheing or will be able to attach additional meta data to the sounds played, which might be necessary for effects like positional event sounds. Documentation You may browse the [40]gtkdoc generated [41]programing documentation of the API. Requirements Currently, libcanberra is tested on Linux only. libcanberra was developed and tested on Fedora Rawhide from August 2008, it should work on most other Linux distributions (and maybe Unix versions) since it uses GNU autoconf and GNU libtool for source code configuration and shared library management. libcanberra has no dependencies besides the OGG Vorbis development headers and whatever the selected backends require. Gtk+ support is optional. An optional lookup cache can be used if Samba's tdb trivial database is available. Installation As this package is made with the GNU autotools you should run ./configure inside the distribution directory for configuring the source tree. After that you should run make for compilation and make install (as root) for installation of libcanberra. Acknowledgements Marc-André Lureau and Brian Cameron for the GStreamer backend. Joe Marcus Clarke for the OSS backend. Diego Elio Pettenò for various build system fixes.
