Pango is a library for laying out and rendering of text, with an emphasis on internationalization. Pango can be used anywhere that text layout is needed, though most of the work on Pango so far has been done in the context of the GTK+ widget toolkit. Pango forms the core of text and font handling for GTK+-2.x.

GTK is a multi-platform toolkit for creating graphical user interfaces. Offering a complete set of widgets, GTK is suitable for projects ranging from small one-off tools to complete application suites.

miniaudio is an audio playback and capture library for C and C++. It's made up of a single source file, has no external dependencies and is released into the public domain.

NanoVG is small antialiased vector graphics rendering library for OpenGL. It has a lean API modeled after HTML5 canvas API. It is aimed to be a practical and fun toolset for building scalable user interfaces and visualizations.

LaGUI demonstration programs

LaGUI is an OpenGL based data driven graphical application framework, it has following main features:

• Widgets driven by properties.

• Fully automatic undo/redo for the entire data structure.

• Multiple working file and file management.

• Any kind of GL canvas.

• Flexible tiling and multi-window interface.

• Game controller/joystick and Wacom pen input support.

• Interface translation and theme support.

• Simple 3D mesh modelling support.

• Very few external dependencies.

Due to the inherit complexity of data structure descriptor for the property driven interface and undo system, LaGUI is not suitable for quick simple programs. It's more suitable to be used as a infrastructure for medium scale tool-styled programs.

Python-nbxmpp is a Python library that provides a way for Python applications to use the XMPP network. This library was initially a fork of xmpppy.

Gajim aims to be an easy to use and fully-featured XMPP chat client. It is extensible via plugins, supports end-to-end encryption (OMEMO and OpenPGP) and available in 29 languages.

OMEMO cryptography library that was forked from python-axolotl.

LV2 is an open specification for audio plugins and host applications. At its core, LV2 is a simple stable interface, accompanied by extensions which add functionality to support the needs of increasingly powerful audio software.

LSP (Linux Studio Plugins) is a collection of audio plugins available as LADSPA/LV2 plugins and as standalone JACK applications.

Sord is a lightweight C library for storing RDF data in memory.

lv2lint is an LV2 lint-like tool that checks whether a given plugin and its UI(s) match up with the provided metadata and adhere to well-known best practices.

CLAP stands for CLever Audio Plug-in. It is an audio plug-in ABI which defines a standard for Digital Audio Workstations and audio plug-ins (synthesizers, audio effects, …) to work together, designed anew for modern processors and capabilities.

Warning: r128gain has been deprecated; the owner recommends using rsgain instead. It is kept here only because it's the only tagger I've found that does what I want -_-'

r128gain is a multi platform command line tool to scan your audio files and tag them with loudness metadata (ReplayGain v2 or Opus R128 gain format), to allow playback of several tracks or albums at a similar loudness level. r128gain can also be used as a Python module from other Python projects to scan and/or tag audio files.
