# General Organization

Only the libraries that are considered to be "standard" are documented:

* `analyzers.lib`
* `basics.lib`
* `compressors.lib`
* `delays.lib`
* `demos.lib`
* `dx7.lib`
* `envelopes.lib`
* `filters.lib`
* `hoa.lib`
* `interpolators.lib`
* `maths.lib`
* `mi.lib`
* `misceffects.lib`
* `oscillators.lib`
* `noises.lib`
* `phaflangers.lib`
* `physmodels.lib`
* `reducemaps.lib`
* `reverbs.lib`
* `routes.lib`
* `signals.lib`
* `soundfiles.lib`
* `spats.lib`
* `synths.lib`
* `tonestacks.lib` (not documented but example in `/examples/misc`)
* `tubes.lib` (not documented but example in `/examples/misc`)
* `vaeffects.lib`
* `wavedigitalfilters.lib`
* `webaudio.lib`
* `version.lib`

Other deprecated libraries such as `music.lib`, etc. are present but are not documented to not confuse new users.

The documentation of each library can be found in `/documentation/library.html` or in `/documentation/library.pdf`. 

A global `version` number for the standard libraries is defined in `version.lib`. 
It follows the semantic versioning structure: MAJOR, MINOR, PATCH. The MAJOR number is increased when we make incompatible changes. The MINOR number is increased when we add functionality in a backwards compatible manner, and the PATCH number when we make backwards compatible bug fixes. By looking at the generated code or the diagram of `process = vl.version;` one can see the current version of the libraries.

The `/examples` directory contains all the examples from the `/examples` folder of the Faust distribution as well as new ones. Most of them were updated to reflect the coding conventions described in the next section. Examples are organized by types in different folders. The `/old` folder contains examples that are fully deprecated, probably because they were integrated to the libraries and fully rewritten (see `freeverb.dsp` for example). Examples using deprecated libraries were integrated to the general tree but a warning comment was added at their beginning to point readers to the right library and function.
