sndkit is a sonic toolkit for everyone. It is a collection of DSP algorithms written in a literate style placed in the public domain. When tangled, the algorithms produce C89 code. When woven, they turn into a self-contained wiki, which can be found here and here.

#I don't see any code here?

The C code is actually contained inside of the org files in the repository. This is how the literate programming style works! It exists in this intermediate markup format, where it can either be tangled into code, or woven into HTML.

#Generating Tangled Code

Code in sndkit is tangled using worgle. For convenience, a local copy of worgle is provided so you don't need install this.

To tangle all the code, run make tangle. This will compile worgle, then run worgle on all the org documents.

Typically, each algorithm will generate one C file and one header file, such as "osc.c" and "osc.h". These are designed self-contained. These shouldn't need to rely on any other files or external libraries (well, other than the standard C library), unless very explicitely stated.

#Example Usage

Many sndkit algorithms already exist pre-tangled in Soundpipe. Have a look at that for some real-world usage.

It is highly encouraged to read the woven output, as they will document proper usage.

#Weaving the Wiki

Wiki Weaving is done via weewiki, so that needs to be installed.

The weewiki database can be generated with make db.

From there, it can be locally run with weewiki server, where it can be browsed from localhost:8080.

To export to HTML, run make export.
