The FAUST home page is https://faust.grame.fr/. The examples in this tutorial were developed using FAUST version 0.9.9.2a2 and updated as needed over time, with the latest version considered being 2.32.1. The name ``FAUST'' comes from ``Functional AUdio STream.''

... diagram.4
On July 26, 2021, Yann Orlarey wrote the following to Faust users <faudiostream-users@lists.sourceforge.net>: ``Faust is inspired by Moses Schönfinkel's combinatory logic (1924) and John Backus' FP (1977). The idea of Schönfinkel was to eliminate the need for variables in mathematical logic. In functional programming, this style is known as `point-free' or `tacit' programming.''

It is inadvisable to publish links into content within the FAUST website, even something as large as the manual, editor, or library documentation, as they frequently change incompatibly. Fortunately, the language rarely has an incompatible change.

... adding16
After running jack-rack, the LADSPA plugin was added by clicking on the menu items ``Add / Uncategorised / C / Constant_Peak_Gain_Resonator''. If jack-rack does not find this or other plugins, make sure your LADSPA_PATH environment variable is set. A typical setting would be /usr/local/lib/ladspa/:/usr/lib/ladspa/.

...jackrackconnect.17
Sound routings such as this may be accomplished using the ``Connect'' window in qjackctl. In that window, there is an Audio tab and a MIDI tab, and the Audio tab is selected by default. Just click twice to select the desired source and destination and then click ``Connect''. Such connections can be made automatic by clicking ``Patchbay'' in the qjackctl control panel, specifying your connections, saving, then clicking ``Activate''. Connections can also be established at the command line using aconnect from the alsa-utils package (included with Planet CCRMA).

Pd must have at least one MIDI-input port defined at startup for this to work. For example, a typical ~/.pdrc file might contain the following startup options for pd:
-jack -r 48000 -alsamidi -midiindev 1 -midioutdev 1 -audiooutdev 1 -outchannels 2 -path /usr/lib/pd/...

...scsynth,22
After restarting sclang, the class name FaustOsc will be defined. In emacs, this is indicated by typesetting it in the special color for known class names. When scsynth is started, you can obtain a printout of the line ``Faust: osc numControls=2'' in the post buffer when the module is loaded, if you remove -DNDEBUG from the compiler flags in either faust2supercollider or Makefile.sccompile.
