LibSMF is a BSD-licensed C library for handling SMF ("*.mid") files.
It transparently handles timepulses conversions, tempo map handling
etc. The only dependencies are C compiler and glib. Full API
documentation and examples are included.
libnoise is a portable C++ library that is used to generate coherent
noise, a type of smoothly-changing noise. libnoise can generate
Perlin noise, ridged multifractal noise, and other types of
coherent-noise.
Coherent noise is often used by graphics programmers to generate
natural-looking textures, planetary terrain, and other things. The
mountain scene shown above was rendered in Terragen with a terrain
file generated by libnoise. You can also view some other examples of
what libnoise can do.
In libnoise, coherent-noise generators are encapsulated in classes
called noise modules. There are many different types of noise
modules. Some noise modules can combine or modify the outputs of
other noise modules in various ways; you can join these modules
together to generate very complex coherent noise.
This is a port of the libshout library. Libshout allows applications to easily
communicate and broadcast to an Icecast streaming media server. It handles the
socket connections, metadata communication, and data streaming for the calling
application, and lets developers focus on feature sets instead of implementation
details.
Sidplay 2 is the second in the Sidplay series originally developed by Michael
Schwendt. This version is written by Simon White and is cycle accurate for
improved sound reproduction. Sidplay 2 is capable of playing all C64 mono and
stereo file formats.
Libsidplayfp is a fork of sidplay2 born with the aim to improve the quality
of emulating the 6581, 8580 chips and the surrounding C64 system in order
to play SID music better.
Libsndfile is a C library for reading and writing files containing sampled
sound (such as MS Windows WAV and the Apple/SGI AIFF format) through one
standard library interface.
The Tremor decoder library is an integer-only fully Ogg Vorbis compliant
software decoder library.
The universal MIDI library is a multithreaded MIDI processing toolkit
which can be used by realtime and non-realtime applications to load,
save, modify and playback MIDI files. The umidi20 library supports
direct playback and recording through JACK MIDI, FIFOs and character
device nodes.
