Ardour Source-Tree layout (July 2017) ===== LIBRARIES ===== A collection of libraries and utility functions. While most are shared libraries, they're pretty much exclusive to Ardour. libs/ **** Independent libs **** - fluidsynth Stripped down (library only) and slightly customized version of fluidsynth use tools/update_fluidsynth.sh to update from upstream - appleutility Utility Classes, abstraction for CoreAudio and AudioUnits (OSX, macOS) - ardouralsautil Utility Class for device-listing (used by the jack and ALSA backends). Device-reservation comandline tool (linked against libdbus), which is also available from https://github.com/x42/alsa_request_device - hidapi Unmodified https://github.com/signal11/hidapi for interaction with some control surfaces (Push2, NI Maschine) - libltc Unmodified https://github.com/x42/libltc/ for Linear Timecode en/decoding - ptformat Unmodified https://github.com/zamaudio/ptformat for loading ProTools sessions - vfork A exec-wrapper which redirects file-descriptors to be used with vfork(2) - qm-dsp Stripped down version of https://github.com/c4dm/qm-dsp The Queen Mary DSP library is used by VAMP Plugins - vamp-plugins VAMP plugins for audio analysis and offline processing (uses qm-dsp) - timecode Timecode (FPS) and musical time conversions - lua Lua Script interpreter and C++ class abstraction - libs/lua/lua-5.3.3 is unmodified upstream Lua-5.3.3 - libs/lua/LuaBridge is a highly customized version of https://github.com/vinniefalco/LuaBridge (C++ bindings) - plugins LV2 Plugins included with Ardour. These are currently mostly independent (a-fluidsynth uses libfluidsynth) - clearlooks-newer GTK theme engine (used by gtk2_ardour) **** PBD dependent libs **** - pbd Paul B-D's utility classes. This is the basis for all Ardour specifics. It provides basic concepts and OS abstractions. - evoral (uses libpbd) Control events, control lists, automation evaluation, parameter descriptions, incl MIDI event abstraction - midi++2 (uses libpdb, libevoral) Standard MIDI Files I/O - backends (uses libpdb, ardouralsautil | appleutility, implements libardour interface) Interaction with Operating System's Audio/MIDI API: ALSA, CoreAudio, JACK, PortAudio/ASIO - surfaces (uses libpbd, libevoral, libtimecode, libardour ;; libgtkmm2ext, libcanvas) Control Surfaces, dynamically loaded by libardour on runtime. - panners (uses libpdb, implements libardour interface) Pan plugins (stereo-balance, VBAP, etc) are dynamically loaded at runtime. - audiographer (uses libpdb) Mini Ardour inside Ardour to export audio-files from sessions. - fst (uses libpbd, implements external methods for libardour and gtk2ardour) VST scanner tool and abstraction for Windows-VSTs to be used with wine or actual windows. - ardour (uses pretty much all the libs above) This is it. libardour runs Ardour sessions. **** UI related libs **** - gtkmm2ext (uses libpbd) Utility Library to extend GDK, GTK, and basic abstraction for UIs and event-loops. This library is not limited to the GUI, but also used for other graphical interfaces (e.g. Push2, NI Maschine) - canvas (uses libpbd, libgtkmm2ext) Cairo Canvas, provides a slate for scalable drawing and basic layout/packing - widgets (uses libpbd, libgtkmm2ext ;; libcanvas utils/colors) Custom GUI widgets - waveview (uses libpbd, libgtkmm2ext, canvas, libardour) Threaded waveform rendering ===== RESOURCE FILES ===== These are bundled as-is. export/ Export Presets mcp/ Mackie control surface device files midi_maps/ Generic MIDI control surface presets osc/ Configuration presets for the OSC control surface patchfiles/ MIDNAM files, MIDI synth descriptions (note-names, CC, PGM names) scripts/ Lua scripts (files with a leading underscore are not bundled) templates/ Session templates (currently none) ===== MISC ===== doc/ Misc developer oriented documentation files and Doxygen patches/ Some .diff files for the build-stack. tools/ Various developer tools, most notably packaging scripts ===== Front Ends ===== gtk2_ardour/ The main Ardour GUI headless/ hardour -- headless Ardour, mostly demo-code how to use Ardour without a GUI. session_utils/ command-line tools using libardour (e.g. export) tools/luadevel/ arlua -- commandline interface to libardour vst wine application top-level (WindowsVST on Linux)
